The site says NOT to use WD40 because it isn't a good lubricant.


Otherwise, there is probably some dust and debris rubbing up against the fan as it spins and is creating excess noise. The fan might have just been noisy from the beginning and not designed for quietness.How do you fix a noisy computer case fan?
have a look inside the tower its probably full of crap and dust etc like mine was
case might be lose , check if any parts are lose ..... I would not spray WD40 ...
No, you are liable to create a bigger problem than what you had! Live with it or replace it! You might clean the crud off of it to help balance it out.
If you take the casing off, it can be that the fan is probably loose and needs to be tightend. It's probably wobbling on the motor and hitting an internal part. If it is squeaking, use 3-1 oil at the base of the motor. A couple of drops will do.
first off, make sure you SHUT YOUR MACHINE OFF FIRST!!!





if you really want to spray WD-40, make sure you shoot a very little amount inside of the fan motor, and spin the fan with your fingers quite a bit to make sure it runs freely... after that, make sure the fan is clean, believe it or not, a dirty fan is a noisy fan.





good luck.
