I recently got a pc and the fans have been extremely loud. When i am not doing much on the PC, according to NZXT my CPU stays at about 38-50 degrees C, which I think is very low. When I play the PC stays at around 70 degrees or maybe cooler depending on the game. If my fans are constantly on full power which I think they are, how do I fix this. Is there some setting in BIOS.
