Im thinking about replacing my loud PSU fan for a 8cm Enermax (which would enable me to run my pc silent or well-cooled).

Most review i've read on the subject either suggest connecting the 3-pin to the PSU (in the case where the cables are molded to the PSU, just connect the fan to those). This feels like little too much for me, so i would prefer to connect the enermax with a 3/4-pin connector, and just unplug the old 3-pin cable from the old fan.

Would this work!?

And how do i know that my PSU is getting sufficient cooling? Because i want to be able to run silent, but not to shorten it's lifelength or anything....

Thanks!

as long as its got atleast 30cfm u should be fine....my psu came with one of those temp controled fans but its setup different....so get a non adjustable fan.

i did that with a 400wt psu i had, i just run it out the back of the psu with all of the other wires and connected it that way.

BTW: READ THIS
u might want to be careful messing around an open psu...even if its unpluged (when u unplug ur pc...hit the power button to discharge all the power left.)
those cappacitors can hold a charge for days without it being plugged in...i meesed with one once and it shocked me so bad that my arm flew back and i fell down...my whole arm and the right side of my head was numb for about 3 hours atleast. just a warning.

thanks for the warning...

it seems like the is no real documented fact on why and for how long your PSU stays charged... so i'll just take it really slow and easy...

There is a way to safely discharge those capacitors. Just take some BIG resistor, and i mean physically big not hight value. Like a 100ohm or so, but rated for hight current/power, and holding it with pliers or tweezers connect it to the 2 legs of the capacitor. That would drain it but without any damage, unlike just shorteninng it with a piece of straight wire.

um, where would i find a big resistor!?

and are the legs of the capacitor the only threat? because if im not mistaken, those should be pretty easy to avoid..

When you install you fan, don't touch any metal that isn't the case the PSU sits in. You won't get shocked. And when you screw the fan in, try to use a rubber-handled screwdriver. It won't hurt AS much...

P.S., Radioshack or a smiliar store has big resistors.

I replaced my PSU fan just a few weeks ago... just cut and spliced the wires, and taped the wires. Nothing hard to it.

It's not the case that the PSU is in that you have to watch out for Devil, it's the large capacitors that will get ya. And unless you're just fumbling around in there, you shouldn't be anywhere near them.

Just remember, OCC, it's staff, it's members, it's affiliates, and it's sponsors are not responsible should anything happen.

Bah, my stupidity left out a word.
I meant to say that that's the only metal you SHOULD touch...oops
Thanks for the correction D3!


Shouldn't that be in almost every post we make?

im done :)
