There is a really annoying clicking noise coming from my com

Sorry, but that's totally a fan. You can hear the oscilations as it rotates. Probably just old/bad bearings from the sound of it.

Most bearing hubs are sealed and best fix is just to replace the unit.

Also know this: PSU's aren't serviceable, it's just a plug in replacement. So get a new power supply and get over it. Want a shock of a lifetime? open up a power supply and fuck with it.
So do yourself a favor, get the wattage rating for his unit and go buy a duplicate or 100 watts more. End of thread.

> PSU's aren't serviceable

Just because you let your fear define your actions doesn't mean we all do. Of course they're fucking serviceable.

Well even replacing fans, the fans are soldered to the board, even if they're a plain ol 8cm fan.

Replacing the PSU is definitely the easiest course of action. If you have a replacement fan and want to install it, that's not too hard to do, either. Unplug the power cord, then hit the power button on the PC. It won't power on, but the request for power should discharge the capacitors.

Disconnect all PSU cables and remove it from the chassis. Remove the four tiny screws holding the case together and slit any "seals" on the seams. When it's opened up, you can use a bigger screwdriver to unscrew the four screws on the fan.

If it's soldered to the board, clip & splice the new one in. If it's a plug-in model, that's easy.

In any case, if you splice, don't just wrap some electrician's tape around the splices. Either use splice buttons, butt splices or wrap the splice in a couple layers of silicone tape to shield them.

Put it all back together and there you go. You won't get fried if the capacitors are discharged. Some people say you should remove power to the PSU and let it sit for about a day. That's good advice if you have time to wait.

So not familiar with soldering irons then..?

"I cannot solder" =/= "not a serviceable component"

It's literally written on the box, and op should know that it's likely soldered to the board so he can consider if he's gonna get a soldering iron or if he's confident in his skills to do this.

Sage for retarded fucking pedants.

With mains voltage and higher, if you're capable of doing any sort of servicing safely you already know it and don't need to ask. If you're asking about it on a message board full of furries, you're not capable of it. What's so hard to understand about that? Those warnings are for average people, and the average person is pretty dumb.

The fans are not "soldered to the board"

The fans are soldered to some wires which are soldered to the board.

There is nothing, other than massive idiocy, preventing you from using crimps, wire nuts, or choccy block.

It says that on Playstations too.
