chattering, changing speeds, I guess it done wore itself out. Can you replace these or is it a matter of a whole new PSU? Seems silly to replace it just because a plastic bushing went titsup.

Most use an 80mm fan, Ã,£1s worth of parts and some soldering equipment or eleccy tape (I use the latter) and youre done. You can either use the psus existing wiring or cut a small hole in its case and run the fans lead to a molex connector.

Think safety tho, touching live heatsinks hurts alot.

Also another safety aspect. unplug it whilst on load. hopefully shouldnt hurt your components in your computer (no worse than just having a power cut) but it means the caps discharge which prevents you from doing anything along the lines of the funky electrician whilst yelling "F**k me!" when you hit a capacitor with the back of your hand.

The 120mm fan died in my Silverstone 600w PSU.  I couldnt be arsed sending it back so replaced the fan myself.  It had a two pin plug so it was quite easy to force a 3 pin plug in its place  Not all PSU fans are hardwired

Goodluck

Ive chopped the end off the old one and soldered it on the replacement, easy and cheap. Cost time, solder and a little insulation tape

Nice. Good advice, especially from M3. Its sounding healthy now, but Ill probably have a poke and a tickle this weekend.

Turn off the pc, unplug it and then press the power button - this works too (I hope ).

woohoo! fixed!  

Took virtually the whole PC apart, cleaned it for the first time in a couple years. Removed the PSU, removed the fan (snip), pulled the center lable off, flushed & lubed, reinstalled, bridged wires with some lamp cord and wire nuts, reassembled and its fixed.
