The fan on my MBA turn on almost at the same time that I start playing a video. It doesn't matter where I am playing the video from - youtube, metacafe, Netflix. Also when the fan turns on it seems like it is running at full speed because it makes a lot of noise and the whining is so loud that it can get very annoying. Anybody else have the same issue with their MBA? Is there a fix for this issue? Btw I am use Google Chrome exclusively as my web browser. My MBA is a 13"/1.8/4GB/128.
