My new Macbook Air's (July 2011) CPU reaches 94 degrees Celcius watching basic, low resolution flash video. Should I be worried?

The fan is inconsistent as well. Sometimes it will stay at 2000 rpm past 80 degrees Cecius and other times it will be at 6000 rpm at 70 degrees celcius. Just watching small flash videos, it hit 94 degrees celcius. In response, the fan only went up to 4000 rpm. Is this normal? That doesn't seem healthy.

MacBook Air, Mac OS X (10.7)

Do a SMU reset.

Also remember your using integrated graphics, so the CPU is also doing the graphics and everything else.



On the other hand my dedicated graphics Radeon 6750M video card in my MacBook Pro barely gets over 100º F even watching full screen videos. Playing 3D games gets it up to 120ºF sometimes. 😉

I don't normally go out of my way to watch flash video but I had never noticed the fan while playing any video but your post caused me to wonder a bit. I went to flashcomguru.com:


http://www.flashcomguru.com/apps/fullscreen_player9/fullscreen.html


and played the video full screen over and over on my 2011 i7, starting the next playthrough immediately after the previous one finished. I know very little about the various editions/makeup of flash videos so perhaps the ones you watch provide a much greater load to the CPU/GPU combination. You might try that to see how your temperature rise compares to mine using the same flash video.


The temperature of my CPU started out at 35deg C. After the first playthrough it had reached 53deg C. After the second playthrough it reached 60deg C. Further playings did not cause the CPU temp to rise above 60deg C and I played about dozen times after reaching 60deg C.


Throughout the testing the fan speed never rose above 2k.


I should also note that I have a Speck clear 'case' which covers both the top and bottom of my MBA so the cooling from convection is likely less than w/o the protective cover.

I played the flash video from the web site repeatedly until the temperature remained constant to within a couple of degrees for ten minutes.


Since others have reported the problem either there is something different WRT my particular unit--I don't think that is likely, but cannot rule it out--or the flash video they are using taxes the system to a higher degree than the fullscreen video I used for testing. To be on the same page others should use the same video:

if you tried everything (smc reset, pram reset...) but if they didn'T fix your problem, your problem is apple's mistake about thermal paste.


apple using too much thermal paste accidently in their factory and too much thermal paste make problems like this.

Does the new i7 MacBook Air run hot ?

I guese everyone that has an overheating MBA, their CPU was assulted with a huge blob of thermal paste.


I just gave up on mine, it's 45-60c when you're doing some web browsing, YouTube 720p HD, Mail, Messenger and iTunes....

As soon as I launch a game (Anomaly, Osmos or EDGE from www.humblebundle.com) the cpu boils up to 99*C and the fan is at 6500 RPM LOUD LIKE CRAZY."
