I bought this PSU to put in my headless server, over 12 months ago. The server was originally in an office, so I did not really consider noise levels. I have since had to move the server to my livingroom and have noticed that the PSU is pretty audible - you can hear it from wherever you are in the room. The server pretty much does nothing other than recording TV programs and serving stuff to other clients on the network (CPU sits at 0% for most of the time, CPU temps are about 30C, system temps 25C, total idle wattage around 25w). Having ruled out that temperatures and load were stressing the PSU and ramping up the fan, I did some tests on a few other parts of the system. My harddrives spin down after 20 mins, so I waited to make sure that none had sped up. I then unplugged all the other fans in the system (CPU and case) and noticed that these were barely audible at all. If it were not for the PSU, I would have an almost inaudible system (which I really want, given that it runs 24/7). I was just wondering whether there was anyone else, that had this PSU, could tell me whether this is normal (a few reviews suggest that is should run very quietly).
