I just recently got an ATI HD 3870, and it runs great, except I think it might be overheating. It runs great for a while, but when I play more modern games such as Race Driver Grid, it starts freezing up as the gpu temperature gets around 80C+. The card is a visiontek 3870 OC edition, but they only OC'ed the core about 25mhz and the memory 25mhz (50mhz DDR). It also has a dual slot cooler. Now I was wondering since this is my first dual slot cooler card, shouldn't it be blowing air out? It seems like its taking in air. I have a PCI slot fan next to it, and I can really feel it blow out air, but then when I go to feel the air from my graphics card, there's nothing blowing out, but it does kind of have a cooler feeling almost like its taking in air. The fan is spinning though, but I can't really tell where the air is going.
My old graphics card was getting pretty hot too, so I'm starting to think I have bad case airflow. I have an Apevia X-Cruiser case which has two 80mm case fans. One on the top, and one in the back. I have it set up so the back fan is intake so it blows cool air over my cpu fan, because my cpu fan blows downwards. Then I have the top one blowing out because heat rises. Is this bad? Should I have the back blowing out? Most computers I've seen, the back blows out, but I figure this is because this is usually the only fan in the case.
I also was thinking about, what if I took my graphics card fan off, and cleaned off the old thermal paste, and put new on? I remember taking the fan off an older graphics card, and the thermal paste job on the gpu was just horrible looking.
Thanks for the help!
