Those stock A2000 PSU's are noisy as hell!
Is it possible to put a low noise fan in there instead of the stock one? What precautions do I have to take to ensure I won't get lethally shocked? I've never opened a PSU before, but I've heard that one needs to be extra careful.
Links to similar projects would be greatly appreciated.

capacitors can shock you pretty good and can hold a charge after the unit has been unplugged for awhile. they can also discharge through a transfomer and shock the spit out of you.
if you touch nothing but the two wires to the fan you should be ok. ive worked on psu's and other high power devices for years but thats me i wouldnt really recommend it for anyone inexperienced.

I´ve changed all my PSU fan's to this: Coolermate.de (http://coolermate.de/gfx/produkte/CMT_%20ALF8S/ALF_80.jpg)
Really quiet, better flow, aluminium frame and it has blue LED :-)
The machines that I changed are: 2xA2000, A3000D, A3000T and A1200T

@Crusher:
Hmm, you wouldnt happen to hold a log or pics of what you did, would you? :-D
I now it's supposed to be easy but I'm dump with electronics stuff, and not too sure of myslef to open up the 3k's psu....

I changed the fan in my A4KT PSU and it was quite simple. Once you have the PSU open you can see what goes where. Just don't touch anything that you don't have to. I am guessing that it would be just as easy to change an A2000 fan....?

Blue LEDs! :pissed:
Not exactly my taste... ;-)

I've changed the stock one on my A4000 psu to a Verax model that's thermally controled through a sensor.
I must admit that the air flow is terrible :-o but then again if I put my hand over the PSU it's cool so probably the temperature just hasn't raised enouph for the thermal sensor to raise the fan's rpm.
The fan was developed for cooling of PC houses so I take it that it's more than adequate (e.g. comparing a high temperature inside a PC case and inside a PSU, it's obvious that the 1st case would be much more harmfull cause that would imply the motherboard and component's temperature was even higher).
The fan I got was THIS (http://www.verax.de/verax.php?SID=143754385e693e797d&template=catalog_entry&entryid=28) one BTW.
