So lately i've noticed a lot of dust building up in my case, so i dismantled it entirely to clean up some of the dust and notice a couple of things, first off my northbridge fan no longer spins(the generic one that came with my abit ic7). second off as i removed the cpu cooler, 2 of the wires just broke off, sadly i don't have a soldering iron so just decided that it was time for a new cpu cooler, i'm thinking a vantec one, since they are silent on selected modes and very cool looking, however i am open to suggestions. Any ideas on what i should do to the northbridge, i can just leave the fan on, and have the only functioning part be the heatsink, which is fine for me, but i'm just a little worried about over heating. Any help/suggestions are appreciated. Thanks
