My XPS is incredibly loud/noisy. The case fan at the back is noisy as well as the CPU/heatsink fan. I'm not sure how much noise is being added by the video card fan or the power supply fan. I think there might be a fifth fan, but I forgot to look for it. Replacing the fan at the back of the case looks easy enough, but replacing the heatsink/CPU fan looks more complicated. Also, I believe there is software that one can use to regulate fan usage based upon temp. settings. Any suggestions on replacement fans, software and other fixes? Also, how difficult is it to replace the CPU fan that sits on top of the heatskink? TIA!!!!!
One thing to do is to move the PC into your garage. Open the case cover. Blow out all of the dust from the fans, case, etc. using the canned air. Move the PC back into the room and turn it on. Check then to see if the noise has lessened.
