How hot dose your iMac run? I am using iStat pro so I'm not sure how accurate the readings are but mine shows the following: CPU 103 GPU 128 GPU diode 128 Ambient 81 Mem controller 117 Airport card 113 HD Bay 128 These are all in fahrenheit. Are these high? I don't have the a/c on here in Houston. Just wondering if I am above or below norm.
