No major issues for me
I purchased my MBA Thursday 3/27. I've read every post I can find on this website and several others re: the overheating issues people experience. I've monitored fan speeds and CPU temperature pretty frequently and have had a generally excellent experience thus far. I just looped the Osama 1080p trailer from apple.com probably 20 times WHILE also running a full screen Youtube video. The fan hit 6200 rpm and CPU temp went to 77 C, but no stuttering, dropped frames, hitches in the sound, jerky mouse, etc. I then put Youtube in the background with the 1080p trailer still running and was able to surf fine with Safari. I let this run for 20-30 minutes and the temperature was stable with the unit sitting on a table. Within 3-4 minutes after stopping the video, the temp was back down to 52 C and fan speed at 2500 and inaudible. My fan ONLY kicks up with extended high demand video.
My conclusion: there are some good ones and some bad ones out there. As others have surmised, there is probably a very critical step in the manufacturing process (application of thermal paste) that if not done exactly right leads to overheating. The margin of error for heat dissipation in this tightly packed, thin case is very slim.
I don't believe, from what I've seen so far, it would be possible (or at least it's pretty unlikely) for me to overheat my MBA doing realistic things. When would I watch two HD videos at once while also surfing the net? Never. I think for my MBA, and probably for a lot more out there, real world uses won't pose any problem.
Having said that, I don't blame people for being pissed if their machine is crappy. If it runs the fans at full speed just surfing the net, or can't do what I just describe doing with mine, then you might want to return it. It SHOULD be able to do HD video, Youtube, etc, without choking, and if it won't then it's defective.
