idle temp is like 43. Ambient temps are high, especially in this hot summer heat. I have my PC in a space between my desk and this printer. I was thinking of changing the PC location.
I don't know about downlocking, the settings on this graphics card is needed to play BF3 because BF3 is a very high demanding game.
The PC isn't really dusty, I'll check it tomorrow and make sure the fan is fully clean.
My last resort is to get an aftermarket gpu cooler if everything else doesn't work.
