Whenever I bootup my Shuttle, the fan goes crazy. It sounds like it is getting jammed, but when i open up my shuttle and tap the fan a little it goes back to normal. I have a 9800 Pro and it was OC'ed to 412/365 (stock cooling). It was running fine at this OC for about a week, then it started doing this. It seems to me like the fan is getting disconnected from something somehow. If anyone has any ideas, please help!
