I have a 24 port switch running my net work, its annoyingly loud when everything else is switched off. The fan seems to run permanently. Its a rack mountable switch, but not mounted on a rack, and it always feels cold to the touch ((been running 24/7 for weeks now), so Iwonder if I could get away with disconnecting the fan altogether. Ideally, I would fit a thermostat switch, just in case it warms up. Anyone know where to get some cheap and simple kit to do that?

Any other opinions on this?
