PSU fan going
2007-01-15, 10:41 AM #1
Hello folks. It seems that a ball bearing or something in the rear fan of my PSU is starting to go. It makes and annoying buzz sounds unless I whack the PC every few minutes and it's really starting to get old. I'm faced with braving hazardous voltages and amperage's in the power supply to replace the fan or buying a new one. It's pretty good (Ultra 600W dual 12v rail with decent amperage's ect, made when Ultra wasn't crap).

I'm not sure what I should do because I really don't have an extra ~60+$ to waste.

Don't mess with it and get a new one. You'll seriously hurt yourself. Seriously.

Well, I don't know how familiar (or clumsy) you are with doing this sort of thing. I've replaced countless PSU fans and have never had a problem. The first one I did when I was like 14. Just stay away from the massive caps and you could be fine.

However, if you die I take no responsibility.

I ordered a new PSU because I had the same problems.

I changed the fan in mine. No problems. Never occured to me somebody would actually buy a whole new PSU just because the fan is broken. Unless it's some strange fan of a strange PSU of a strange case model by one of the big corporations, and can't be replaced.

It could be a good idea to shut down your computer for the duration of the work, if you are afraid of electricity.

Well I got a new one because my fan would make noise so I would whack the PSU and now I'm getting file corruption and video artifacts and warnings that my 12v is too low so I ordered a new one. :)

Is there some way to discharge the caps?

You could throw small pieces of metal at them...

Unplug it while the computer is running, you may not even need to do that on a modern power supply.

Simple way to find out, though, check with a DMM. Or you could just wear rubber gloves throughout the whole process. And make sure you are wearing shoes.

How about poking them with some metal tongs whilst standing barefoot on a metal floor? :P

Thanks for all the help guys!

You could also try giving it a bath!

Oh, yes it's probably very dusty! Thanks for the tip!

Heh, great timing. Mine is buzzing like crazy at the moment. Very bloody annoying.

I hate anything to do with PSUs. It takes so long to remove them and then properly organize the 80ft long cables again.

just so you know, if the capacitor discharges into you, you'll be dead.

have fun!

There are great many things in this world that can easily kill you. Changing the fan of a PSU isn't the most likely one, though.

Besides, there's no reason to have the capacitors discharge into you, is there? At least I didn't find any when I did the job. And it won't discharge hazardously through the fan wires.

In my experience very few PSUs survive the warranty period, so it's much more sensible to just get a free replacement.

You can just oil the thing. Remove the fan, pop the plastic cap and put a few drops of 3-in-1. No need to replace the whole thing.

Now I'm not usually a grammar nazi, but what the **** inspired that apostrophe there? Seriously, you got the plural of 'voltage' right, so why would 'amperage' - a word that clearly ends the same - suddenly require an apostrophe in plural? Misusing apostrophes for plurals is pretty standard, but switching mid-sentence? Really, just think about it.

My guess is that the sound is actually your fan hitting loose wires.

Yeah I got that after I jammed two fans into the front of my case next to hard drives 3 and 4; there was so little room for the wires that the fan blades kept hitting them and making a buzzing noise. Thankfully it wasn't anything that a bit of hot glue couldn't take care of.

It's because Google toolbar decided it should go there and I was too lazy, or perhaps in too much of a hurry to fix it, even though it bugged me too.

You could lick your PSU.
