I've been having some issues with my computer fan. I cleaned all the fans but that didn't seem to help. It's an older part (krpw-ss500w) but not sure why it's running so loud recently. There doesn't seem to be a heat issue... could it just be getting louder because it's old or somesuch?
Bought a replacement and gave it a try, seems to be equal amount of noise. The quality of the noise may be slightly different with the two PSUs but total amount is about the same. I'll probably return the new one since it doesn't seem to make any difference (and it's slightly less energy efficient than old one).
