Video card damaged?

[[+Duracell-]]

So I just installed a new HD4850 in my system, and I was running Oblivion when all of a sudden my screen turned black with blue squares in a weird pattern. I promptly turned it off and let it sit for a bit, thinking the temps were a bit high.

I get back into windows, and sure enough, they were getting high. I found a thread where you can adjust your fan speed in a CCC profile, so I did that. Ran a few things to stress the card and I got screen corruption and freezing when sensor #2 (according to GPU-Z) got around 100C.

I let it sit for longer. I installed a fan up front, thinking more airflow might help. I have an Antec P180 with only one fan in the rear sucking out, and it's worked fine for my previous config. Turned it on again. When I got what was supposed to be the Vista login screen, all I got was a garbled screen of pixels and colors.

I have my old card in here now, and the HD4850 is sitting out in an anti-static bag cooling off. It's quite possible that it didn't get a chance to cool down after the second time because it was still quite hot when I took it out. I'm going to try again in a bit, but what are the possibilities that could have happened? I swear my old card (X1900GT) has ran at much higher temps and nothing has happened to it.

Sounds to me like you cooked the card...

Maybe it's just me and my crazy way of thinking, but I can think of hardly any situation where a modern enthusiast system run in an Antec P180 would need only the rear exhaust fan going. Maybe running a low end Celeron-D with integrated video or something, but certainly not an overclocked E6320 with an HD4850, both of which are going to put out lots and lots of heat.

Your X1900GT ran at 'much higher temps' than 100C!!??


Anyway sounds like RMA time!

Well, I never had any problems with heat up until now. After I dusted out the X1900GT, it's running at 65C idle/85C load. Before it was 75/95 or something like that. My CPU temps rarely hit 45C load.

I just reinstalled the HD4850 and same thing happened, so I'm just going to RMA it.

Stick some more fans in your case as well. Running with only a single exhaust fan, especially in an enclosed case like the P180 is a recipe for problems. The 4850 puts out a lot more heat than the X1900GT, so you can't use that to judge how much cooling you need.
