|Yes, please don't run your computer with a faulty system fan. You can repair the fan, but most of the time it is just easier to replace it. If you did want to repair the fan, you will first have to take it off the heatsink. Next on the back of the fan there should be a sticker that covers the bearings. Remove the sticker and under that there will be a c-clip that holds the axle in. You must remove that retaining clip and the fan assembly will come off the base. |
Now get yourself some q-tips, de-greaser, and some house hold oil. You are going to want to clean the bearings with the de-greaser "house hold cleaner" very well, and you will want to cut one end off a q-tip and clean the bearings all the way through.
Next dry everything off, add just a little oil to the bearings and reassemble the fan, don't forget the clip. So that sticker that you took off is most likely destroyed by now so use some packing tape to cover the area that you took off the sticker and a razor to trim the tape to approximation the same diameter of the original sticker.
Now re-assembly the heatsink and test. Hopefully this works for you.
