Bought a Club 3D Radeon HD 4850 off of eBay from a seller that (apparently) normally parts out systems (as in this card wasn't for his own personal use). Plug it in, works right off the bat. It doesn't overclock well and after a while, I start getting BSODs. Suspecting temps, I loaded up FurMark and let it run. Wham. About 110 Celsius load, mid-50s idle. It's set at the stock 664 core, 990 mem. Voltage reads 1.12v. FurMark has been running for 30-ish minutes and I don't seem to have trouble with stability. A review at Fudzilla shows that this card should be doing somewhere in the low 60s under load (nearly HALF of what I'm getting now). The card does not appear to be modified in any way. I did notice that the card almost seems like it's sagging down (bent slightly), drooping near the 6-pin power connector. Otherwise, the card looks exactly as it does in the review. I have some OCz Freeze and AS5 that I can stick on it, but I'd rather not touch it if I need to return it. The heatsink is warm, but not as hot as I would expect a heatsink attached to a 110 degree GPU to be. The fan is indeed spinning. So, what do you think? Ask for a return or clean up the heatsink and reapply paste (and return anyways if it doesn't work)? Furmark: Sensors, temps, settings, etc: Edit: Ambient temperature of the room is about 27-28 celsius. Hotter than your average room, but that gives me a 83 degree rise over ambient. Powering down to remove the card and reseat the heatsink.
