I bought a refurbed h80 from scan and it appears one of the fans doesn't spin up. It twitches and if i give it a gentle nudge it'll start but then stop after a minute or two. Does it sound like a problem with the H80 or the psu or the motherboard maybe? The psu is a coolermaster 500w model and the motherboard is an asus p8p67, which is refusing to even reach post atm but I suspect it may be down to me connecting something wrong while half asleep, but may also be the psu. This turned out longer than the quick question I wanted it to be.
