This guy gave me a video card to try out and he doesn't know if it works. It came with a fan originally, but the fan is missing. I was wondering if it's safe to try it out, even for 30 secs. without a fan, just to see if it works. If it's not safe, how long would it have to run without a fan for damage to occur? I know with a CPU it's not safe at all, and even if you try to run without a fan for 10 secs, the CPU could fry. Is it the same with video cards?
