Basically what the title is, I'm using MSI afterburner to smash the cooling fan to 100% to bring the temp down during games, but its still high after I cleaned it out.
Good advice Internity.
But Fletcher, you should take a look at the other components in you PC perhaps something is heating up your GFX-card, perhaps the southbridge chip.
Hm. My Evga GTX460 is running at 45% fan speed, on idle around 35°, 45-60° while gaming depending on the game. And it's summer, my room is very hot usually.
As I said, those values aren't nice, but the 470 gets very hot.
