After I removed the fan of my Revo R3600 in order to change the hard drive it became incredibly noisy, sounding a bit like a motorbike. Given that it was in the lounge I needed to do something about it. At work one evening I realised there might be a nice big heat sink in a recently deceased Dell Optiplex 380 (I think) desktop. There was, and it was an amazingly good fit, though it's not properly attached (yet). I use fancontrol to switch the fan on at 60C, and it doesn't come on often. The piece of paper is blocking a hole in the fan, forcing all the air to pass through the heat sink.Ideally I'd get rid of the fan and stand the case up to let the air flow naturally through the heat sink.
