Hey Guys!
My XFX's HD5770's fan died yesterday!
Is the card out of warranty, if not go and apply for RMA.
- will save you money;
- just might get lucky and get a better performing card.
Anyways, if you want to add a VGA cooler then hit these sites -- Theitdepot - Lian Li Graphics Card Cooler (BS-08B) / Cooling Systems / Cooling Devices / Overclockers Zone.
Hope this helps and happy gaming [soon]. Cheerio!!
Also, do you recommend applying thermal paste?
