7AM repair job- PC PSU cooling fan

It stopped spinning some weeks ago.
The PSU turned very hot.

A lot of dust had accumulated!

But the fan did not spin anymore at all.

I had an idea!

Maybe dust would have made it's way between the magnet and the coils.

I tried to pour some white spirit into the fan, and soon, the fan again would spin freely.

After powering up, it works again!

I have inlined a 3W red LED as well, to reduce voltage.

Low speed is enough, since I do not use all available Watts.

Good work I think.

I tried the same method on a tiny GPU cooler as well. In a few minutes, it was spinning again!

Just a little white spirit did the trick.
