I have a PSU whose fan bearings are going bad. Every now and again it produces a loud screeching sound for 5 to 10 minutes, then returns to silent running.
I've looked at videos describing how to replace the fan, but am confused. It looks way more complex than I think it ought to be. I suppose the connectors differ from those used on case fans. In my mind, I should just be able to snip the two wires on the current fan (including its connector), snip wires on a spare case fan to get rid of its connector, and solder the old fan's connector to the new fan's wires. Total time: 1 minute.
That seems way simpler than desoldering wires from their contacts on both the old and new fan, then soldering the connector from the old fan to the contacts of the new fan. Total time: 10 minutes.
Is there some reason for going through all that?
