I've been hearing a roaring in my computer which I eventually traced to the fan on the video card. Dust removal didn't help and I think its almost dead. The card is a TI 4200. The fan is a 50mm with a two pin connector. I think I could get the old fan off if I could find a replacement, but I didn't see anything that would fit at Newegg. Would the card be ok without a fan if this one dies? I wouldn't mind spending a few bucks on a fan, but I really don't want to buy a new video card right now if I don't have to.
