Hector said:the extreme editon is a 75w tdp cpu, it's still too hot for the imac though, regular conroe is fine though.
Ah, just seen they've updated the specs since releasing them. The TDP used to be 90W but its been lowered to 75W for 2.93GHz and 80W for the 3.2GHz. Still I'd prefer a silent iMac to a louder more powerful iMac.
