I recently got a new PSU with two fans. THen I got a new case. I'm trying to run a blue LED fan theme throughout it, so I was wondering if it would even be possible to switch out fans in PSUs. Is it risky? Worth it?

I also guess I would have to know how to solder well, huh? I know how to, but I'm not the best
Edit: Just as an FYI, this is the PSU I have.

you may not need to solder anything
Some just have the same plug you would find on your MB
*Edit, it will also void the war. if you open it

Not hard, but risky if you're careless. There's high voltage in there so if you accidently drop a screw or a blob of solder in the wrong place and fire it up later, you may see sparks. Needless to say you also void the warranty - most PSUs have a lable you have to cut or tear to open it so they know if you've been inside.
The fan is a standard 12 volt fan. I usually just cut the wires off the old fan, splice the new fan wires to the old ones, solder them together and cover with heat shrink tubing.
If you don't know how to solder you could just twist the wires together and cover the splice with electrical tape.

Raise your hand if all you've ever used is cheap power supplies. *raises hand*
I have never had any problems with the ones we sell at he shop. We pay 19 bucks for them.

I've never liked using electrical tape, as it will come lose with time and temps. You could use electrical screw caps available at any hardware store.

I just replaced mine a few weeks ago and used simple wire nuts. (the small gray ones) No fuss finding the right connector because its was simple splice job and left the original connector in.
If you go that rout you want to cut off up to a half inch of insulation off each wire, twist them together and fold the exposed part half way back thus doubling its thickness.. The little gray ones are a little too big without doing so to get a good grab and you want that. There insulated so a short shound't be a problem. And um keep your nuts away from the fan..
