I built my pc a bit less than 2 years ago, and recently the fan in my powercolor pcs+ 5870 card has started rattling. It kinda sounds like its hitting something when its running, but as far as I can see it is not, and if I gently press the middle of the fan while its spinning it stops.
I have tried cleaning the dust out of it, but it no avail, any ideas what it could be and if its fixable?
Peel back the sticker covering the back center of the fan and there will be a small hole. give it a drop of.lube. I prefer mineral oil but WD40 or motor oil should work. just a little and give it a flick, then put the sticker back so dust doesn't get in.
