Haha, one time while I was still aircooled, I was workin on lowering temps by adding fans
. I placed a couple of beautiful 92mm panaflow fans blowing freash air on the cpu balanced on the video card leaning outwards. They were taught on thier own power cords. Anyways, I was working in there and i bumped one which caused it to fall into the exposed corner of the video card instantly throwing fanblades everywhere.
So... I whipped out the super glue and glued the 2 broken blades back on. Amazingly enough, the fan came out just as balanced as it was before. It doesnt wobble or make any more noise than the perfect panaflow.
So I switched to water cooling. No more broken fans.
