how do you connect fans with 2 pins/wires

philip_pc · 5th April 2005, 8:49 PM

i got a crappy yumcha PSU lieing around which i am thinking of disembling due to the reason that it has a 120mm fan in it, personally i think the fan is work more than the PSU itself, the PSU is some unknown brand so i dun wanna risk using it and sure that no one wants to buy it so i took it apart last night and niticed that the fan had a 2wire/pin connector..
my question, how do you wire these to the comp? cause the MB connectors are 3 pins arnt they?

Just wire it to a molex connector, you will more than likely blow a fan header with a 120mm fan.

Red to +12V
Black to GND

just to clarify what nuxie1 has said, on the fan red = 12v, but on a 4 pin molex yellow = 12v.

so to wire it into a 4 pin molex (which also recommend doing), you would connect the fan's red wire up to the psu's yellow 12v and the fan's black up to either of the grounds on the psu.

hmm. i'm not so sure i made that clearer.

That actually crossed my mind as I was posting but I thought Red was +12V on a molex so didnt add to it. But yellow is +12V whoopsies..

It is said, "that a picture is worth a thousand words..." (even with my basic graphics skills

) so here you go

haha it works a treat.
thanks for the help peoples
wire isnt long enough to actually mount it to the side so its just sitting on the case floor now blowing air up towards the CPU......
i have ALOT of copper wiring, when the dude was installing the AC there was alot left ova, i just stripped them and got all the copper wires (had to do an assesment back then)...
would i be able to extend the fans wires by using these copper wires?

Are the wires insulated?
