For some odd reason, my computer stays nearly silent during normal use, and even stay silent during a full-blown 10 minute stress test, but as soon as I am in certain games (Deus Ex: Human Revolution) my PC gets extremely loud. Both my outtake fans are controlled manually by a switch, so it's only my intake fan and CPU heatsink fan. I have a stock intake fan and a CoolerMaster Hyper 212 Evo heatsink and fan.
Is there any way to keep the volume consistent? I know the fans don't need to speed up since it can stay quiet during a stress test.
check if there is a way for you to get intake and outake fan with more cfm power and if you could send more air to your graphic card that will help to reduce the speed you gpu fan have to go to cool it
