My Radeon 4670 fan probably has some problem and I wonder if anyone went through this and how they proceeded to fix it (if possible). It does a huge noise when I turn on my computer. The catch is, if I touch the fan it becomes silent again. Sometimes it insists in being noisy but I can always insist into touching it (and eventually stopping it completely for half a second) and it stops. Once it stops it only happens when I turn off the computer for some hours and turn it on again.
I push the card to it's limits in games with no overheating or other issues at all. So, anyone else has ever experienced that? How can I detach the fan to check it out?

First take the card out, then remove the fan. Take the fan apart or at the least the sticker if you have any motor oil or WD40 and re-oil it. That will take care of the noises after that put the fan back on and pop the card in.
