My Targus Chill Mat is having an issue with the right side fan. It does not run smoothly like the left side does; it has started running jerkily at best and makes an almost-but-not-quite grinding noise. I was initially able to solve this problem by banging on my desk, but it appears to not be a permanent solution.

Is there anything I can do to stop this, short of buying another one?
