The fan on my psu has died. I opened up the unit and it is just an 80mm fan. The only problem is it is wired to a logic board or something. Can I buy an 80mm fan a wire it to the psu?
 
Solution
Fan replacement isn't exactly complicated. Power off the supply and unplug it, wait a day or so and it will be discharged enough to handle. If you are in a hurry you can discharge large capacitors with any stout piece of metal (but that may involve dismantling it while the capacitors are still live, not recommended)

If the fan is soldered directly to the board just cut the wires as close to the bad fan as possible. Use the remaining wire to solder the new fan on, or install connectors.


If you're asking the question, don't.
Either RMA, or just buy a new one. We don't want someone to come home and find a charred husk that used to be you.
 




Well now, let's not get carried away here. While you could take a discharge from the PSU caps, it would be mostly all voltage and very little current. (Loud bark with a little bite). I still wouldn't want to be on the end of it but unless it passes across your heart, you will likely be shaken up, but OK.


I will also agree with USAFRet, if you're asking...... don't do it.

Solution
You can also remove the AC cord from the power supply, and while leaving all the internal cabling connected and AC Power Switch = ON.... Press the PC power button ON/Off three to four times. The power supply is still loaded(connected to the motherboard) and without an electrical supply from the wall, this will drain most/all of the capacitors.
