I have an ATI RADEON X600 video driver. I play team fortress 2 a lot, and about 2 months ago I started having trouble where my pc would crash after 5 minutes of playing, which I later found out was caused by overheating of the video driver because dust blocked the fans ability to cool the video driver.I followed instructions people gave me and used a can of compressed air and a vacuĆ¼m to clean out the whole inside of my pc. the fan was allready too damaged to work on it's own, so I had to spin it up manually upon booting up my pc. now my expectations came true and the fan finally broke and doesn't work anymore, at all. does anyone know how to fix the fan, or find an alternative way?
