I have a 2.8 GHz Intel Core i5 27" iMac. It is two years old. It feels very hot. I have downloaded iStat nano and the temperatures (degrees Celsius) are:
HD: Macintosh HD 54 °C
CPU A 55 °C
GPU Diode 63 °C
GPU Heatsink 57 °C
Ambient 23 °C
Memory Controller 53 °C
Optical Drive 52 °C
Is this normal? I am a little concerned. Please advise.
