I have noticed that the CPU and GPU temperature are quite high on my system.
The CPU runs at around 44C-52C when idle and when gaming or running anything CPU intensive it shoots upto 60C-65C
My system specs are:
Intel Core2Duo E8200 2.66Ghz
Nvidia GeForce 9800 GT 512MB
320Gb WD HDD
32 bit Windows XP
