MBA 2011 i7 Overheating Issues - interesting new findings on page 3

try watching something via netflix and see what happens. sounds like a plane is about to take off on my i5, but it is otherwise pretty quiet.
Interesting... Makes me wonder if I've got a defective unit hereRight 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?
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.

When I look at the OPs I don't see any images other but the Bandwith exceeded images..
Is this normal or am I loosing the plot?...

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.
Try imgur.com. It can handle 100,000+ views and GBs of traffic for a single image. Most of the images you'll find on a popular linking site reddit.com use it.
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.
So the movie is now playing and CPU hovers at 5-7% busy.
I let the download buffer for a bit and I am playing the clip again
CPU Usage remains where it should and so do the temps. Enclosure temps are excellent.
I am now going to play the clip a couple of times and will post screenshots

First of all, i'd like to say thanks for the imformational posts theSeb, you've swayed my mind to buy the 13' i7.
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) Any help would be greatly appreciated

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)

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.
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?
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

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!
