sounds more like an os problem to me than a fan problem.

cpu fans are spozed to suck...in air that is and cool your precious cpu

*pets cpu all "the one ring" like*

euhm anyways

maybe there is some probgram running on startup that shouldn;t run.....had it a while where it toook me nearly 10 minutes to get to my desktop...found out it was some n00b trying to break my system....and failing

*is not trying to worry you*

if you download cpucool you could check your cpu temp and see if it is indeed cooling good or not
