    I'm considering replacing the 92mm fan in my Enermax PSU with a quieter Papst fan. But is there anything to the warnings on the outside of every PSU to not remove the cover? From what I know about electronics, capacitors inside the PSU don't hold much charge but this charge can be released quickly resulting in a high current for a short period of time.

    I would suggest using an insulated screwdriver or long-nose pliers to short out the contacts of any electrolytic capacitor you can see ; either short the capacitor contacts (to each other) or to the PSU case. Also short the output leads before you undo the case.
