I am playing GTA IV on highest settings (1280x1024) and my temps reach 59 c with the stock fan spinning at 5700 rpm
so is this normal or I need an aftermarket cooler
so this is my rig
cpu: phenom II 955 (underclocked to 2.5 ghz to decrease temp and 78 Watt and 1.33 voltage)
gpu:msi radeon 5770 1gb
note:using zp thermal compound (accidentally had a problem with stock thermal paste so had to remove it)
An after market cooler would be a good investment for you i run a Cooler Master Hyper TX3 with a phenom II X4 945, I never go above 35 degrees even though mines a step below yours I recommend the same cooler for you!
