I've noticed that my 27" iMac gets really hot all along the upper portion of the aluminum behind the screen, with especially high intensity towards the upper-left-hand corner.


It's so hot it actually hurts to touch it.


I downloaded the iStat Widget to get a factual read on the temps.  Here are the numbers it reported (in degrees Farenheit):

HD = 135

CPU = 113

Ambient = 81

CPU Diode = 140

CPU Heatsink = 137

Mem Controller = 130

Optical Drive = 124

Power Supply 2 = 140


Are these numbers too high, or are they within expected range for this system?




iMac, Mac OS X (10.6.8), (27" 2010)
