So i have a late 2009 21,5 iMac and whatever i do it's sooo hot! Like right now just typing this or watching youtube it gets up to 50 degrees celsius... It does not get any hotter than that and i'm not running any specific programs that are big. I have SMC Fan control but just asking should it be that hot? I know the aluminum case works like a heatsink but really 50 celsius hot???
The 21.5-inch, Late 2009, iMac has either a E7600 or E8600 Intel Core 2 Duo with a TCASE (Case Temperature is the maximum temperature allowed at the processor Integrated Heat Spreader (IHS).) temperature of 74.1°C and 72.4°C respectively. So if the CPU is reading only 50°C, then it's not running hot at all.
