I'd advise to use a different computer as you may overheat your computer and damage it. Which fan isn't working? The CPU or the Graphics Card?
DO NOT GAME with it like this. You'll fry whichever for sure.
I worried about that also. The CPU Fan didn't work at the time but when i tried a different graphic card. My old HIS 4670.CPU heatsink fan is moving normally again. So i'm hoping... If i got a better graphic card. I'm wondering will it still work on my motherboard?
Can you list your system specs? Include motherboard, power supply, processor. Did you have a video card in there before or were you using onboard video? Providing you haven't knocked something loose like the cpu fan connection, then its possible you have a motherboard/power supply issue.
I just build my computer today that why i'm on a tight budget.. I had a bit of a minor problem but other than that everything running smoothly.
