it sounds like ur fan berings are wearing out. go get some graphite lube and give her a squirt. now that summers aproching my computer runs hotter but i got enugh fans to keep it under 40. right now im at 32c. asus and soyo are best mobos out there on the market right now. i think i have that same oc vid card, but i have as backup if my geforce 6800 ultra goes to hell. newegg has some great stuff. go take a look, and always read the coments on products
