Annoying fan noise

[azteched]

I put a Kama-Bay in my new system, with an Akasa blue LED fan replacing the standard one. All was fine yesterday, but today it's making an annoying clicking sound.

If I put my hand over the intake at the front, it stops - does this provide any indication of what the problem could be?

I've checked nothing is catching on the fan from behind (no cables anywhere near)..just wondering if the fan could be catching on the dust protector in the Kama?

Well after a bit of poking around and loosening a couple of screws a little, it was a bit better..

then while poking some more, my screwdriver sort of missed its intended target and hit a fan blade (pc was on ) . This seems to have cured it!

Nah fan is fine I think, it must have moved it a bit or something, causing the noise to go.
