North Bridge fan clicking fast

Basically what the title says. My computer turns on and after its halfway booted, my North Bridge fan turns on, but begins to click very fast. Any suggestions on making it stop?

You need to do a visual inspection to make sure there's no obstructions(ie: wires, bugs etc). If no obstructions then maybe try putting a really small drop of the lighest oil you can find. Otherwise, you can just buy a replacement.

Ugh, i hope there is just an obstruction or its on crooked and not the fan. I don't really want to buy a new one. Anyway thanks for input.
