Hmmm am I the only one who's iMac is cooler (in the temperature sense ) after the update? I put my hand on top and it's only warm now. Before, it was HOT. I've had my iMac running for about 3 hours (CPU 37º, GPU 51º, Memory 41º, Airport card 58º, Hard Drive 45º) At these temperatures before the update, my iMac was running HOT. Now it's just warm. Anyone else got a similar result from the update? (No other real noticeable update except less crashing/freezing) iMac specs in signature.
