My MacBook Air is a vampire

[mac82]

Anyone else notice that when using the Air 13 in sunlight, or in a brightly sunlit room, the fan revs up to 4000 or 5000rpm with even the slightest CPU usage, such as streaming a 360p YouTube video or downloading a file in Safari -- things that usually do not heat the CPU sufficiently to require the fan. Under normal lighting conditions (indoor lighting, slightly overcast sky, etc) I can stream a 720p video from YouTube without heating the CPU sufficiently to require the fan; it stays at 2000rpm. BTW, this doesn't seem to have anything to do with temperature; the difference in temperature between a sunlit room and a room with the shades drawn is less than 1C. It seems more to do with the brightness of ambient light (even though this machine is not supposed to have an ambient light sensor). What are your experiences?

I believe that it has everything to do with temperature. That is what sunlight is known to raise, and is why computers rev up their fans. Don't forget, while the room may be only slightly warmer, your MacBook has a nice, large, black keyboard. Get some sun shining on that, and it'll add a bit of warmth to your laptop. I experience the same thing occasionally in bright sunlight (I live in Florida, the Sunshine State) on my Air.

My Blackbook does similar things. It revs its fan just sitting idle in the sunlight.
