How to quiet a noisy PSU fan?

Post #339,922 by drook 2/19/11 4:15:23 PM 2/19/11 4:15:34 PM Reply	How to quiet a noisy PSU fan? I see lots of forum posts about the fans spinning up and sounding like a jet engine, but that's not what I'm getting. Mine have a slight rattle, like a fan is unbalanced. I haven't pulled the PSU yet to blow it out, since it's the one piece of a G5 that's not easy to get to, but I'd like to know if it's possible to replace just the PSU fan before I go pulling it. -- Drew Edited by drook Feb. 19, 2011, 04:15:34 PM EST Expand All History

There's usually a peel off label on one side of the fan. Just peel it off and drop in a drop of fairly thick oil (e.g. Motor oil). Spin it around a little, stick the sticker back on, and you should be good to go. But with the hassle in getting to that point, you might just want to replace it. Assuming you can get a part number or equivalent before you start the disassembly. HTH. Good luck. Cheers, Scott.

I have found no cure for this except a new fan. Fans are cheap and easily available for PCs, and easy to replace (Power Supply fans need a little soldering of the leads), but I don't know about Macs - Apple likes proprietary everything.

You need push up the thing from the back of it as its a push in and lock setup. You will need a long stiff item with a slight bend.
