Hi.
I've been having this annoying problem on my black Macbook (purchased in Dec. 2006) - the fan is kicking on at full blast power when I switch on the machine or bring it back from sleep. It does so for perhaps 30 seconds, and then switches off, then switches back on intermitently in 3-10 second bursts for the next few minutes. After a while (I'm assuming as soon as its 'warmed up'?) it cuts off and I don't hear it until the next time I bring it back from sleep.
I have taken this to the Macstore 'Genius Bar' on two occasions in the past month - the first time they couldn't replicate the problem (which is ridiculous but it does this every time I switch it on). They ended up only installing FanControl, from which I've been able to roughly guess that as soon as the computer reaches above 40C the fan always stops. They second time I took it in the guy at the bar heard the fan noise and replaced the logicboard - but that doesn't seem to have done the trick. Strangely enough, when he booted the machine from his own external hard drive it didn't really make the noise.
I've uploaded a video of the problem to YouTube if you want to hear what it sounds like.

This can't be normal behavior can it? Any help anyone can provide is greatly appreciate.
