This is literally driving me nuts. I've been tinkering with CoolBook on my Rev A Macbook Air 1.6 80gb Every time I play flash video, it almost instantly starts heating up and my fans go up to around 6200 rpm. I've been searching everywhere and still haven't found a fix to this... Can anyone please explain me exactly what I'm supposed to do to prevent my MBA from overheating so much? I've installed flash 10 and still no improvement. Thanks.
