So let's get real about this.

I was sorting out the accounting for my business this evening and working out how much VAT I can claim back and figured I would do some testing as well to keep myself awake. I am holding the MBA on my laptop

Start:

CPU is idling. I have Chrome running with 4 tabs, Finder, PathFinder, Desktop Monitor and I've put on a SD episode of Family Guy. Chrome is downloading the latest Xcode and IOS Beta. Note that I've muted the sound so that I can hear the fan.

Fan is inaudible at tis point, unless you put your ear by the enclosure in a silent room.

So what'a happening 4 minutes later?

Everything is fine. MBA feels cool to the touch, but the CPU temp has risen. Fan is still inaudible.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at210704.png

Everything is still fine 8 minutes after the last screenshot and the fans remain at the same point. The CPU temp has risen slightly, but there is no noticeable heat from the keyboard or to my lap.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at211502.png

Ok, I am getting bored now so I've opened Mail, Itunes is playing music, Word and Excel is running and I still have VLC playing the Family Guy episode in the background.

Nothing significant to report. Fan is still quiet and the CPU heat is normal. I am using Excel and Chrome.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at212755.png

So I've decided to open iCal as well

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at213128.png

Still nothing interesting to report so I've decided to also copy a large file from an external drive over USB 2.0 (which is CPU dependant). The CPU temps rise slowly, but keep a lookout on the enclosure temps. Nothing significant to mention. Fans remain at round 20xx.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at213500.png

CPU temp is rising but it's still not an issue to the keyboard or the bottom of the enclosure. The top left is warm now.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at214724.png

Ok, nothing exciting is happening so I am now going to encode the mkv files I've just copied.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at221153.png

I've already posted a screenshot of what happens when you're encoding so there are no surprises here. I am still busy working in the background without any issues. The CPU temps are rising and the fans have kicked in. The fans start to become slightly noticeable at around 2800 RPM. If you're about a metre away (3 feet), then you cannot hear them. Enclosures remain at acceptable temperatures. The very top left is quite hot, but not an issue for the keyboard. The only keys that are warm are Esc and F1.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at221734.png

I've stopped the encoding and a minute later

So let's watch a 1080p file (mkv) using VLC. CPU remains at around 23% throughout . CPU temps climb, but not an issue to enclosure temperatures. Fan remains at inaudible levels for now.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at225408.png


Ok, the fans are increasing a bit now to cool down the CPU

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at230223.png

I am working as the movie plays and the fans climb to around 3000 RPM. As mentioned before, the fans start to become slightly noticeable at around 2800 RPM. If you're about a metre away (3 feet), then you cannot hear them. Enclosure temps remain at acceptable temperatures. Even at 3600 RPM the fans are barely noticeable. Don't forget the audio is on mute.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at230456.png

Nothing exciting to report

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at230542.png

I am busy with a couple of things. Fans are happily spinning away.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at231019.png

So I've decided to check what happens if I only watch the movie and stop working. You cannot hear the fans at this level unless you put your ear an inch or two away from the top left corner.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-23at231614.png

Temps are starting to drop and the fans are doing their job (still barely noticeable)

Heat and noise issues? You decide.

Your last photo had battery levels @ 6%. Did you run the battery all the way down until the MBA shuts down? Also, how long was your battery life from a full charge?

You did get a great i7 MBA. In my case, my 13" i7 MBA will hit 94 or 95C when Handbreak is encoding videos.

My machine stays at 50C when idle. I just replace the thermal compound this afternoon with AS-5. Now MBA does calm down to 42C when idle. I am waiting to see the final result.

Thanks for your post.. As a poster pointed out in another threat , this is a forum for rumours , rather than facts.... :D:D

So the new Air will not set itself on fire and it can play a 1080p movie no problem while multitasking... I think that says it all. Thanks for your effort!! ;)

Interesting... Makes me wonder if I've got a defective unit here :( Right now my cpu is at 58 celsius and the fans are at 2k rpm. Only got safari open with four tabs + 1password. No background apps are running. When watching an episode of house last night on safari (flash) my cpu was around 80c and my fans were blazing at 4k rpm. Had maybe 4-5 tabs open and no background stuff. Anyway you could test your heat and fans while watching fullscreen flash with sound?

What I did was let the computer run all day. It didn't go to sleep. Maybe it just needed to index itself till it was good and ready. I'm still at 48 celsius and 2k rpm.

The temp rose all the way to 90 celsius and about 5000 rpm. I just imported 11gb with of photos into Aperture. Seems like normal activity?

After some time I can get it to 96 C and the fans up to 66xx whilst encoding. I've a screenshot of this in my other thread. This is normal and what I would expect. The computer does not shutdown nor does it scold my hands. As a comparison the only other Apple laptop I have is a 2009 C2D MBP. It reaches around 95 C whilst encoding and you could fry eggs on the top left corner.

No. I had already done that when I first got it. It was busy downloading throughout the test so I plugged it in after it got to 5%.

More likely we are witnessing some firmware or driver issues. Remember these are brand new machines, and the 1.8GHz Core i7 used in the Air was just released by Intel on June 21. Some bugs that cause the CPU to stay at the higher speeds may be at issue here. Apple had the Core 2 Duo models last October, which were mostly fixed by firmware updates, so I'd give it some time.

FWIW, I'm encoding a DVD on Handbrake right now, and when it started all 4 cores were near 212F/100C, with Handbrake using about 350% CPU (so most of all 4 virtual cores). I could boil water with it if I wanted to, but it has since stabilized at 185/86. It's about as CPU intensive as you can get, but the machine's still plugging away, and I'm posting to the site as it's encoding in the background.

I just downloaded handbrake and give it a go. About 10 mins of encoding, my 2.13GHz C2D started off max 83C, fan spinning up and once the fan pass beyond 6k, the processor hovers around 73C~76C.

I purposely switch off my wall fan that usually also cool the MBA a little, and I tried to put it on my naked lap, it's just slight warm. I live in SEA region so it's summer all day. Looks like the i7 indeed run quite a bit warmer.

Fan taking 2 mins or less from 6.5k back down to 2k, due to the CPU dropped from 70C+ to 50C almost immediately after handbrake stop encoding.

I'm going to use the laptop at constant high CPU processing, guess I should keep my C2D as it has plenty of juice for my need for audio works while keeping the temperature low for my all year summer region.

By the way what makes Hulu/Netflix heating up? I tried watching 1080 youtube video at full screen for few minutes, the max I've seen is 70C and the fan begin to spin up slightly but still silent.

Update: after more than 10mins of watching 1080 youtube total, CPU dropped to 67C and fan hover around 38C, and that's with wall fan switched off.

Not necessarily. The Core i7 will be at maximum CPU for a lot less time than the Core 2 Duo at a comparable task.

It's necessary, because I'm doing audio production works and working with plugins will have the CPU working ALL the time. It's not time attack mission, it's real time processing until I finish working and close the DAW.

So what about youtube 1080p?


I was busy "poncing about on the computer", as the mrs calls it, so I did not allow the MBA to return to idle temps. This way it's a more realistic test of doing stuff and then immediately watching a 1080p YouTube clip. You can see what version of flash I have.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-24at085800.png

So the movie is now playing and CPU hovers at 5-7% busy.

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-24at085931.png

I let the download buffer for a bit and I am playing the clip again

http://i52.photobucket.com/albums/g35/da_seb/mba2011/ScreenShot2011-07-24at091010.png

CPU Usage remains where it should and so do the temps. Enclosure temps are excellent.

Now to my question, you said the program that displayed the info about the computer on the desktop was desktop manager? Is it available in the mac app store, or how do you get it?

Secondly, have you done any other performance configurations on your computer? (I'm a windows user atm, hopefully not by the end of next week :D) Any help would be greatly appreciated :)

Ok.. in the previous thread when quoting Sir Winston Churchill -

I WAS TALKING ABOUT MYSELF.

I was not implying that anyone else was stupid, rather I tried to say that I was afraid to ask if the images should be seen or if there was some "magic" way of seeing them.

Hence, I quoted Churchill and the said that even though he said how it is better to keep quiet, I needed to ask how I can see the images.

It was not my intent to say that theSeb was an idiot. Why would I, the guy has done a great service to all those who were interested in heat "issues" in relation to i7 13" MBA.

I am really sorry if what I wrote offended anyone, in particular theSeb, but that honestly was not the intent.

I was taking the piss out myself when admitting that I did not know the way to actually see the images.

Sorry...

It's DesktopMonitor and it's on the Mac App Store. I've not made any changes to anything in terms of configuration or settings. This is out of the box config with a couple of applications installed. You can find more info on my MBA here. (it has the Samsung LCD the the Samsung SSD)

http://forums.macrumors.com/showthread.php?t=1193767

Just a quick update. I've watched the clip a couple of times now. Temps hover around 66-70, depending on what I am doing in the background. To explain further, I left the clip to play on full screen, but I check the temps occasionally. I've noticed that if I am doing something at the same time as the clip is playing, the temps rise about 1 or 2 degree, which is normal.

Enclosure temps remain great and only the very top left corner is warm along with the Esc key, but I can keep my finger there indefinitely without any discomfort (this was a major issue for me on my previous MBP). Fans have not ventured past 20xx. The sound is muted and I am sitting in the lounge with nothing else on (the mrs is still sleeping).The Sky HD box (kind of like your Tivo thing for those in the US that have no idea what I am talking about) is about 3 metres away from me. It is on standby and I can hear it. I cannot hear the MBA until I put my ear right by the top left corner and then you can hear the fans. They're working away happily and very quietly. One thing to note in all of my screenshots is the Heatsink temp. Does anyone know where the sensor is located? It seems to stay at a very reasonable temperature.

80C+ and the fan is not running pass 4k? Looks scary to me...

Heatsink and enclosure temps remain at acceptable levels. I would imagine Apple is still looking for the perfect trade offs between fan noise and CPU temps with these computers. CPUs are designed to run at hotter temps than what we're subjecting them to. I do quite a lot with my computers. It's my bread and butter, my passion, and my hobby. If the chip fries, I'll get another one. :)

Edit: Typswif2fingers, don't stress about it mate

next time i'm ordering a mac i'll avoid the respective sub forums untill i receive it .. the only thing you get is buyers remore before you even have the thing



compared to the current old pc i'm using (as replacement for my way too old mac mini) it will still be a marvolous and relativly quite machine

Great work! Do you mind telling us what was the channel you bought your MBA
- Curious as both your display and SSD are Samsung's. I am wondering if that rare combo is helping you achieve the results you got.

Thanks!

I just checked the price in UK and it's 100 for the 13" and 150 for the 11". UK prices seem quite expensive... For the 13" it's actually 14% more expensive than where I live (Sweden). That's despite us having higher sales tax (25% vs 20%).

However, even here in Sweden, the 13" i7 upgrade is very expensive compared to the US. Deducting the 25% sales tax from the Swedish price, the upgrade is still 15% more expensive than in the US. Apple really needs to get their pricing sorted. They made a half-assed attempt with the release of the new Airs, but it's still way off. Examples for the 13" (with the sales tax deducted from the Swedish prices):

Base price: +17% more expensive than US
SSD upgrade: +26% more expensive than US

Sorry for going slightly off topic. Love your report. Really makes me comfortable with ordering the 13" ultimate.

I bought mine from the Apple Store in Regent Street, London. I don't think the SSD and display variances could have anything to do with how the MBA runs though. :)

Edit: just a small FYI for all without making a new post - the i7 is rated to go up to 100 degrees Celsius safely

Edit: just a small FYI for all without making a new post - the i7 is rated to go up to 100 degrees Celsius safely

Yep. People have a tendency to think that whenever something is hot enough to burn you, it must be pretty bad. If Intel's rigorous testing and validation has determined that 100C is safe for these chips, I'd trust that.

thanks theSeb for the postings, it sure gives some of those who ordered the i7 and haven't received it yet a nice peace of mind

next time i'm ordering a mac i'll avoid the respective sub forums untill i receive it .. the only thing you get is buyers remore before you even have the thing



compared to the current old pc i'm using (as replacement for my way too old mac mini) it will still be a marvolous and relativly quite machine

very very true, also i think that people who have problems will post and those who don't won't - there must be loads of people with 13 inch i7 without any problems.


I still think it is worth reading peoples posts though to see if there are any big issues

Your screenshots indicate youre using a defective version of Chrome (it has the fullscreen icon in the upper-righthand corner. Might want to try Canary. They've been updating it since Lion came out.

I just did a similar test on my 13 inch 2010 Air running Lion with Chrome Canary and then with Safari, both 1080p and both fullscreen. Canary ran it perfectly, never a hint of the fans. I closed Canary and moved to Safari, let it buffer about 2 minutes and then started playing. Within 15 seconds of starting in Safari the fans were at full blast. Shut down Safari, opened Canary and ran the same video again and no fans and much lower CPU usage. This along with the fact that Safari leaks memory like crazy is why I'm sticking with Chrome.

Heatsink and enclosure temps remain at acceptable levels. I would imagine Apple is still looking for the perfect trade offs between fan noise and CPU temps with these computers. CPUs are designed to run at hotter temps than what we're subjecting them to. I do quite a lot with my computers. It's my bread and butter, my passion, and my hobby. If the chip fries, I'll get another one. :)

Edit: Typswif2fingers, don't stress about it mate

Others, why are you guys paying 130 for the upgrade? Is that the price in Europe?

Its 130 with full educational discount :/ Just like the 256GB SSD upgrade is just over 200.

My 11" Ultimate will cost around 1200, just 400 less than my current maxed out 15" Pro. One thing is for definite, I'll be swapping it over and over until I get all Samsung parts. I'll have plenty of time to spare before Uni starts anyway.

Does i7 actually run hotter than the i5? I am debating between the 11 inch models but advice or insight on either size would be cool.

That's a tough one. The xbench on the Samsung was about 360. Thoshiba was 315. Hard to say since the i7 has both display and SSD Samsung. It might, but nothing that will vastly increase it. Wish both computers had Samsung SSD to get a better comparison. So I say minimal at best. The speed here is within the processor.

As long as it runs within Intel's specs, it does not shutdown or freeze and stays ok to touch and hold on your lap, what's there to worry about? Nothing.

Agreed! Guys the i7 is a great machine. Don't worry about the heat or fan. I'm probably one of the pickiest guys when it comes to my apple products and I'm happy with mine. Once you iron out all the indexing and loading your apps this thing is a beast!! I'm just amazed on how something so small can be soo powerful.

I've not had a chance to just sit in front of the computer and do simple things in one go to be able to form any opinions.

Some interesting new findings:

A couple of days later I've noticed that the CPU stays cooler. It gets up to 95 and then drops back down to below 90.

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-25at143930.png

The fans are obviously going, but the CPU is hovering around 80 - 86

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-25at144949.png

This is the lowest that I've seen during encoding

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-25at144949.png

So I thought that I would try again today to make sure my findings are consistent. Unfortunately I missed all of the drama at the beginning, because I was occupied. The CPU went up to around 95 again and the fans kicked in, but I also noticed that the CPU Usage Idle went to quite high and then the temps started to stabilise. I am not sure if the Idle number going up means that the CPU is actively throttling itself, or not.

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-26at221420.png

Now fans have dropped back down to 5400, which is nice and everything seems to be great

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-26at221713.png

This was really interesting. I decided that I would give the battery a quick charge and also see what happens when you plug it into the charger. I've noticed in the past that a laptop usually gets warmer when you're charging it. This is what happened about 20 seconds, if I recall correctly, after plugging it in.

Fans back up to 6000+ and the temp back to 90+. Also take note of the CPU Usage Idle %

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-26at222002.png

So what happens if I unplug it again? Note the temps, the CPU Idle and the time difference

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-26at222055.png

And we're back to what appears to be a stable place for encoding

http://i52.photobucket.com/albums/g35/da_seb/ScreenShot2011-07-26at222525.png

Or not? The fans kicked in again and now we're down to 78

I've had similar stuff happen with my 2011 C2D Air. Would be nice and quiet while I did stuff on battery. Then heat up and have fans go to 3600 or so when I plugged it in. Not all the time but enough to notice. And C2D don't have TB. Think it might just be a "fans are more likely when charging" kind of SMC setting.

At least for the MBA, it's common to see the system run hotter when plugged in and charging. After the battery is charged, the temperature should be the same regardless.

I noticed this on the 2009's 2.13GHz Intel Core 2 Duo MBA when I had it. It ran hotter on AC then Battery by quite a bit.

Copied over a ton of data, played some flash video, played some local encoded video, skyped with my dad in AZ for an hour, and tested out Civ 5 (it plays just fine on recommended settings--all low). The MBA only got hot with skype and Civ 5 and the fans only kicked in when gaming. This is a great machine. Don't sweat the deets.

I have the 11" i7. I downloaded smcFanControl the other day and at first i had trouble using it. Now that i have it working well i can boost up the fan speed to 4.5k rpms and then start streaming video, running 2 windows of safari, mail, and xcode and the temp never rises above 65. But i had it plugged in all the times i did that so i dont know how it affects battery life.

Hello, nice with some good testing going on :)
I did some full load tests (13" 1.7 GHz i5 in apple store) with cputest where after I ran geekbench to check performance afterwards. The geekbench was about 1000 points lower directly after the "full load" run than when idle, so I suspect thermal throttling. Have you done any benchmarking after having handbrake on for some time? It also would be interesting to monitor cpu frequency while encoding in handbrake.

Handbrake for Windows is 32-bit only. That said, it seems to be oscillating between 1.8GHz (native speed) and 2.6GHz (Turbo Boost at dual core). It has temporarily hovered at different speeds (1.4 GHz, 2.4GHz), but it mostly splits time between 1.8GHz and 2.6GHz. I can't tell the load on each core since CPU-Z doesn't reveal those details, but Norton Utilities was kind enough to throw out a warning that one of the cores was at 100% utilization.

I'm encoding a standard resolution DVD and am getting an average FPS of about 70fps.

The fan is going at a fast clip, but again, I don't have the exact speed.

Update: About 20 minutes into what would be a 60 minute encoding, the CPU is staying at 1.8GHz more, but still occasionally boosting up to 2.6GHz.

I have not read how Apple handles it, but all of my PCs throttle back the turbo when the laptop is not hooked up to external power.

This means it will run slower (and cooler) when not plugged in.

When on AC, the CPU will run faster, and this hotter.

This is not about battery charging temps, etc.

Hello, windows task manager should show the load on each core, you can start it by typing "taskmgr" in the run menu (if I remember correctly), or bring it up by pressing ctrl-alt-delete if you're using windows 7. However, it's not clear that handbrake will fully load all cores all the time. If not, it would be better to use a program that equally stresses all cores like Prime95.

LOL, I've had about 4 different unibody MB/MBP's and 3 of them had heat issues. My 2009 MBP reached 107 degrees and when I returned it to Apple they said it was within limits.

It's a known issue that insane amounts of thermal paste is applied to MBP's, causing more heat development than usual. Search around this forum and you will find lots of people who disassembled their logic board and re-applied thermal paste, gaining much lower temperatures.

There are videos of people literally cooking eggs on their Macbook's, so saying "do you think Apple would release it" doesn't fly. They would and they did.

I am afraid that I can't. Netflix is not available in the UK.

If you want to be able to watch Netflix in the U.K or any other Web use that is dependent on your location, I suggest using a public VPN service that makes it possible to select a VPN in another country. The IP address will indicate that the server is based in the U.S., so Netflix is not blocked.

Around five years ago I reviewed multiple public VPN services and I eventually settled on Witopia.net. It has VPN servers all over the world and a number of encryption options. VPN access is controlled via Viscosity which places a tiny icon in the Finder Menu Bar. VPN is initiated via the icon while a drop-down menu shows all the server options.

Pricing varies depending on the kind of VPN you need and there are bundles that include VPN for iOS and other portable devices like the Android. If all you need is VPN for a Mac the price is around $3.33/month. An OS X/iOS VPN account runs around $5/month. Multi-year subscriptions offer nice discounts; since I have a three-year subscription that I got in a special offer for $99, the prices are estimates based on my somewhat fuzzy memory regarding the various pricing options. All plans allow unlimited data transfers.

Installation is very easy (Viscosity is part of the supplied installation package) and Witopia customer service is excellent. There is a 30-day money-back cancellation period.

While some VPN services slow down the Internet connection, Witopia's often equal and sometimes surpass my Charter 10mbps broadband connection.

VPN encrypts all data transfers so it ensures a safe public WiFi experience and your Web usage cannot be monitored and logged by your ISP. VPN should be considered essential if you spend a lot of time utilizing public WiFi and wired hotspots.

I took this screenshot at the 2 minute mark. I was idle the whole time. Interesting enough was when I started using the web to post this response, it dropped a few more degrees. But when back to idle, it heated up. :confused: Anyways just thought I'd share with you. Maybe the heat is due to Lion and the apps it's using since they haven't been "fully utilized" to Lion OS?

As you can see the temps are 78C and fan is nearly at 5700 rpm. The movie didn't come out the screen shot. But the point here is that the temps on the i5 vs i7 appear to be the same. The lower temps are mainly while at idle. So I'm not sure i7 is subject to more heat. :confused:

I went for an i5, my corporate machine has an earlier i7 which does a fair impression of a "hair dryer" :) I know it`not "Apple for Apples" :rolleyes: My i5 idles at around 40C and so far has not ramped up the fans. Playback of an iTunes movie will see CPU temp rising to low 50C`s, ambient is around 25C.

Still loading software, so we will see so far very impressed with the new air, runs cool and compared to my "toasty" MacBook Pro 2Ghz 4.1 blazingly fast.

I am running SNC Fan Control as it is just an application, it installs no startup scripts, background processes or daemons. You can choose to start manually or on login, at the end of the day the more system monitors, processes etc the bigger the impact on the battery life. With SNC I can see CPU temp and fan speed which is good enough for me, ans can set default`s for Battery, AC & Charging, which is very useful as it far easier to keep a system cool, than try to cool a hot one down...

The i7 has a place for some, yet for the vast majority the i5 is more than enough. Short of the odd video encode I would never stress the machine.

Do you actually place it on your lap? I thought most placed something in between?

hey guys - long-time user 1st time poster. I bought a 13" i7 a week ago and was concerned about the heating issue, especially after perusing this thread. I would hit low 90'sC, 6500rpm with only low-def youtube and word running (monitored w iStat). It would idle b/w 50-60C. Performance was fine but fans were driving me a bit crazy...

Anyway forced myself to replace it today and went for another i7 after testing it in the apple store w basically every app open. Idles at 40C and runs 1080p vid, word, iTunes, multiple safari tabs at ~70C, fans ~3500rpm. Very relieved! - get it replaced if ur concerned ;)

Did they say whether the heat fault with your MBA i7 is a fault they are aware of or is it just one of those defective models that happens in all manufacturing?Did they give you any trouble when you wanted to swap it?

The only istat I see is a widget - where should I be finding the desktop overlay app?

I checked with a few store workers and none were aware of it as a widespread issue - guess mine was probably defective :roll eyes:
On the plus side they were very obliging when replacing it - didn't even put the 1st one to test!

That's good to hear nothing worse than at a fight when trying to get something replaces that broken especially if they don't want to admit a wider issue

The application is called Desktop Monitor and it is available on the MAS.

Mine is very comfortable, even at 60-65 degrees

Makes me wonder if mine was defective.

Allright i've gotten my 13" i7 air aswell now, have been doing some testing and so on, only found one strange thing (that isn't related to windows/osx gui differences).

I've been trying out xbmc as a mediaplayer and found a perculiar thing. When playing a sample of a 1080p movie (transformers) on an external screen using a hdmi adapter the fans are perfectly stable, however, when leaving the player on but no movie playing (or simply starting the program and not selecting a movie) the temperatures skyrockets and within one minute i hit 90 degrees celsius, while fans do spin up I decided to kill xbmc when i hit 93 degrees, doubt it is an "air" issue, but I was wondering if anyone else have noticed this (or would care to try to reproduce it).

To clarify, xbmc is run on the external screen in fullscreen mode if that makes a difference.

I've got an i5 and i7 11-inch and in many cases the i7 runs a degree or two C cooler than the i5 for the most part. For the most intensive tasks I do (exporting and converting music files) the i7 can get slightly higher from a temps perspective but they drop a lot quicker than the i5.
