1167817 2011-01-06 22:30:00 The fan in my PSU has seized. PSU still works (computer gets power fine) but the fan no longer turns around, so the PSU gets REAL hot :)

I have switched out that PSU for one with a working fan, but I would like to get the fan working again if possible. Is there a way to unseize a fan in a PSU? The fan power is soldered into the fan so I can't switch it out easily for another fan...

Any suggestions? Seems a waste of a good PSU when just the fan doesn't work?

Cheers,
Mike.

1167818 2011-01-06 22:41:00 You can see how much longer it will run by applying a small amount of light oil to the bearing but it is likely that the bearing is stuffed. Peel back the foil on the centre to get at the bearing. Also clean all dirt/fluff off it.

Easy enough to cut wires and solder new one on if you have a soldering iron and can find a good fan.

Good luck.

1167824 2011-01-07 05:19:00 The super nasty way to do this is to bolt another fan to the outside of the computer, over where the PSU fan normally vents.
If doing this it may be best to cut the power to the seized fan and to remove it, or break off the fans fins so that it's not obstructing the air flow.

Super nasty, but effective.

It is quite possible to take the old fan out and fit a replacement.
Make sure the 400volt rail is discharged before you stick your fingers inside.

1167826 2011-01-07 06:04:00 I have replaced PSU fans several times, It's very very easy.

Just need a new fan (standard 80mm or 120mm or maybe even 90mm computer fan depending on what your PSU is like) and a soldering iron

If you don't have a soldering iron find someone who does. They should be able to replace the fan in 5 minutes, [thats how long it would take me.]

If it would take them half an hour or more then they don't know what they're doing.
