The fan on my Asus 9600XT is making weird noises and I need to replace it. I've never done anything like this before, but I'm hoping it's not too tricky. Anyways, where can I find a fan that would work on this card? Also, if there are any good links on instructions on how to replace the fan, that'd be good too. Unfortunteately I can't find the box/warranty so I can't send it in.
