As soon as my mac wake from sleep, the fans start running crazy for about 30 seconds, and then slow down until normal. Anybody heard about that problem?
Thanks for your help.

Yes, it can happen if your system was very hot when you put your system into sleep mode.
Also make sure your firmware is also up to date for your system.

It happen even if the computer is cold, and the firmware is up to date...
OK, then you could have a bad sensor. Download from the App store Temperature Gauge and see what it tells you.
I installed the app, and when it happen the temperatures look normal but the "Average Fan Speed" climb to almost 1400 RPM. Very strange. In some forums, they say a cause may be a dirty sensor. I alway keep my computer clean. Other say that it is probably "Snow leopard" that has an unsolved bug. (With "Tiger" everything was OK).
If your system can support Lion or Mountain Lion you could try that.
