Ive been using the default intel hsf that came with my processor for the past 6 or o months now, but now for some reason the fan on it is making a grinding noise thats just getting worse by the day. Can you guys give me some suggestions as to a good aftermarket fan to replace this one? The noise is driving me nuts.. and im afraid that the fan is just going to break while the pc is running and fry the proc. any help would be appreciated.
