this is getting really annoying. my pc is starting to sound like a car engine. there's some fan in there thats gettin really loud. i changed the psu to see if that would make a difference, but it didnt. my graphics card fan is too small to make this much noise. my best guess is that its the heatsink fan. now does this mean i have to replace it? i know theres dozens of hardware devices to control fan speeds, but is there some kind of software that can do the same thing ?
