Ok so I have a 9800GTX+ 512mb card, the fan on it just fell off while i was playing online. I can put it back on but when I do and turn the pc back on it sounds like its grinding against it somehow, my question tho is can you fix that ? and if I continue to use it without the fan and use like a house fan directly on it will that help or will it ruin my motherboard , I am a noob with all this so that is why I am here
