    Informal poll. Does your fan kick in to high gear (6500rpm, loud) almost immediately when viewing YouTube videos?

    Pretty much. It'll definitely hit 6500 if you open up a few of them. Don't worry ;)

    Which youtube video would you recommend?

    I'd say no, but I'm not sure which youtube video you are referring to :confused:

    My Air is left leaning, so I would guess any video of George Bush might send it over the edge. But then again, any video of that mean old lady running for President seems to cause an immediate Shutdown.

    I can't believe Apple made a mistake with the thermal paste again....

    I watched a few and my fans stuck it out around 2550 RPM or so with 130F temps. I'm sure it depends on what you're watching though.

    I have one word.


    It sucks on OS X and eats every little CPU cycle it can. It's software and not hardware related.

    Thanks for your replies. Hmm I didn't realize different videos would cause different behaviors. I was just going to YouTube and clicking around on different stuff to see what happens. If you want a specific example, I was watching this:

    But please be warned it's kind of dirty! If you are easily offended please don't watch it, I don't want to get kicked off macrumors for posting offensive links! It is the funniest thing ever though, but that's a different story. Anyhow I'm just using it as an example because it's long. My fans kick in very audibly after watching this a few minutes.

    I am just freaking out because I have had my air a week and I love it, but the fan runs very very often, which is something that never happened on any of my previous macs (mbp, powerbook, ibook, etc). I am leaving for a week vacation tomorrow so if I am going to swap it out, I have to do it tonight, it's my last chance. If this is how they are, obviously getting a new one won't help. But if there are ones out there that have more normal fans, I would prefer that. If the ones available a few weeks from now have been adjusted so the fans don't run so crazily, I would much rather have one of those, you know? It's just so hard to know what to do. I once had a powerbook where the fans ran all the time and it wound up being swapped out and the new one behaved totally differently, so you never know.

    Anyhow that's why I posted a specific question about YouTube, just wanted to know what other users were experiencing.

    Ps I have the 1799 model not the ssd one.

    My fan kicks on after a few minutes of American Idol clips from Youtube. Then after a few more minutes, one of the cores shuts down and everything becomes jerky and slow.

    I watched a few mins and my fan stayed at or around 2500. I do have the SSD model, FWIW.

    my fan doesn't go above 2500 rpm until I hit 79 deg C. and I watched a youtube video, obviously not that one.. since I'm at work, but it was still at 2500 rpm.

    Yeah and this is not really a problem because very few websites still using flash technology today... :D

    How does the Air work on Sirius satellite's Flash heavy website? I have ordered an Air but worry about videos and sites like Sirius'.

    I watched a 4:30 clip from YouTube just now and after two minutes or so the fan started to kick in, ending up at 6200rpm.

    What wonders me most is that on my CD MacBook and C2D Macbook Pro the fans slow(ed) down within seconds after the task has ended. Air seems to keep the fan up for a longer period and have a slower decline in the CPU temp, even bouncing back up by a degree or two. Makes me want to shout to the ventilation holes "hello, is this thing even connected?" :rolleyes:

    Also I find it a bit amazing that watching some 720p .mkv files stresses the system so much it has to yank the fan up to 6200rpm even with cpu load being around 50%. Then again, it does start stuttering after some time and the load is past 1.10 while CPU still has time to spare.

    I'm using 1.8/64

    I ran it and my fan didn't kick in at all.

    I'm still just trying to figure out of this is "normal" for this machine, or if they are going to get tweaked so they are not quite so sensitive. I also feel like my battery drains REALLY fast even when just emailing/web browsing. I'm getting *maybe* 2.5 hours max.

    When I'm watching videos on youtube my fan goes up to 3500/4000rpm and the temperature reaches 65 Celsius (I've just made a test on youtube and spent 20 min watching videos, a 9min one and 4 3min vids), my friends' MBA on the other hand reaches around 78 and the fan does go up to 6500 C ... I have the SSD, and he has the HDD.

    But my MBA does reach 80 C and 6500rpm when I watch movies on iTunes. And I have never experienced any lag like other people say...

    I guess I'm lucky...

    I have the SSD 1.8 and no problems with watching YouTube videos here....the machine does not become excessively hot and the fans don't roar.

    Flash is a killer

    Any Flash app/whatever will cause heavy cpu use and the fan spinning like crazy. I´ve tried this with both safari and firefox and they´re both the same.
    this happens on windows too, occationally.

    Just ran this on my MacBook Air (1.8 GHz 64 GB SSD) with no issues.

    Watched the full length of the YouTube video :

    Temps :
    CPU A 65 degrees
    Fans (2,499 rpm and fluctuates to 2,502 rpm)
    CPU User : 18%
    System : 10%

    So far, mine looks good, hoping that it'll last. :)

    OK ok

    My fan just got stuck at 6200. Temps were low at 50C.

    It just would not slow down so I put it to sleep then resumed at it was normal

    So there's a problem here.

    What sort of bugs me is if I wasn't a geek constantly monitoring the fan and temps with 'Harware monitor pro' I would not know that the thing is malfunctioning (broken)

    But this sort of thing is easily fixed with an update.

    Apple is going to need to know about this issue.

    now it's doing it again..... arrrrrggg

    It's porked it seems.

    cpu is at like 4%, all apps shut down except finder, temps at 49C

    yet dumb fan is roaring at 6200

    it's not like I can find a process that's doing it cuz with cpu at 4% that's not it.

    anyone else have this going on?

    at idle speed with only Safari open i watched a 2min YouTube video and at the end of the video my fans where at ~3100 rpm and my CPU load was 32% (specs in sig).

    i think the MBA fan issue while watching Flash videos comes down to two factors: software and hardware.

    Flash software on Mac OS X sucks (as Eidorian said) and uses too much CPU power causing it to get hot so the fans start to kick in to cool it down. for example watching a 720p video in QuickTime player will use about ~20% CPU load while a piss small Flash video will take up ~30% CPU load. Adobe get with it! and while your at it make a universal binary Shockwave plug-in!

    MBA's have the least powerful processor in the Mac line so coupled with Flash software the CPU will be under more load than any other Mac and become more hotter causing a higher fan speed.

    Are those with the problem running a new clean installation of osX or as the factory delivered them ?
