As the thread title suggests, my Compaq Proliant server has an extremely noisy PSU. I've tried running the server with the cover off and disconnecting all the interior fans (not recommended to leave running in that condition), and none of them is as noisy as the PSU fan itself.
In addition, the PSU fan sometimes creates an annoying wavering/beating sound, like when you have two sound waves with a very slight pitch difference between them. Even though I've located the server downstairs, as far from the bedrooms as possible, I can still hear this noise in my bedroom!
As you might expect, this is very annoying. I'd like to ask if anyone here has had experience with these kind of PSUs, and would perhaps know what the problem is. I've taken out the PSU and had a look at it, and there are rivets and screws all over the place. I'd like to open it up and replace/repair the fan - perhaps a drop of oil on the bearings would help - but cannot figure out which screws to undo.
Has anyone here ever successfully opened up one of these PSUs? If so, maybe you could walk me through opening it up to replace/repair the fan. Might also be a good opportunity to check for bad caps
