Mainboard Fan

[John Smith (archive)]

I had my system go down today with a faulty power supply. After changing it and getting the system up and running, I noticed a small fan on the mainboard was stopped ( Not the CPU fan - it is running OK) Could this have caused my power supply failure and should I change it ASAP. When I gave the fan a little spin, it began running at a seemingly reduced speed (the fan is about 1 1/2 inches square with a lead to the mainboard)

TIA

No.

and should I change it ASAP.

Yes.

I would replace it with a Thermaltake Blue Orb or Orange Orb, whichever is cheapest.

Since you haven't told us which board you have, its hard to give specific advice. However, it is probably just your Northbridge fan. These fans pull very little juice and it is extremely unlikely that it caused your power supply failure. The fans failure can lead to occasional lock ups, but many users have simply removed them. The usual problem with the fan is a lack of lubrication. When mine began to fail I simply placed a single drop of machine oil under the sticker that covers the bearing. You can also replace it.

Then it's not dead. Just pull it off and peel the sticker in the middle back and drop a very small amount of lightwieght machine oil in it. spin it a few times to get it spinning freely and then put it back together.
