Why? What's wrong with it?

take it apart, unscrew fan, just like any other fan.

It is a sleeve bearing fan which has a shorter lifespan

Yes I know how to change a PSU fan. That is a mains powered appliance and in many countries you are required to undertake proper training and hold a license to practice electrical work. It is a very simple job but the fact you are asking means I think youre going to stuff up somehow and do something dangerous

The capacitors inside the PSU can hold a charge that an electrocute you even when it's unplugged.  Generally you ground the PSU to drain the charge before tinkering with it.  If unsure don't attempt it for your own safety.  75USD on a new PSU is better than getting physically hurt.

What PSU is it? Changing the fan in a shitty unit with a sleeve-bearing fan (as opposed to a decent PSU with a sleeve-bearing fan like a Corsair CXM) isn't really worthwhile and you have to solder as the fan connections in PSUs are usually two-pin connections that don't work with the 3 or 4-pin connections on a normal fan.

It is the Corsair CXM (grey). You guess it right.

Hmm, well I guess you can try doing it but you'll void your warranty. I think @Energycorecan help you lots with this topic.

Well as people have already said you should be very careful with the capacitors inside a PSU. When I open a PSU to clean the dust off, I use a brush with a plastic handle to take the dust off along with compressed air; I generally avoid touching the capacitors or any component in there really.

 

As for switching a fan, it's not a terribly hard job, but you might have to whip out a soldering iron. It will void your warranty, 100% guaranteed.

 

Open up the PSU and see where the fan is connected. It may be soldered to the main PCB, have a small connector like the ones on your usual graphics card, or a big one like the ones on your motherboard. On this third case, you have nothing to do except plug the new fan in there, hide the cables and rescrew everything.

 

It's the other two cases that need soldering. The one with the small connector, cut the connector off the old fan, the connector off the new fan, and solder the new fan to the small connector. If the cables are stuck to the pcb, solder the fan onto those cables. Don't try to solder into the PCB if you don't have the right equipment!

 

Most of the time it's a pretty simple process if you already know how to solder. Isolate the cables with something like heatshrink and you're good to go.
