Not a chance and quite pointless.

get a 12DC converter. All you need is .5A for most 25mm fans. 1.5A for the high powered 38mm fans.

You can goto radioshack and pick up a universal one. Make sure its a VDC or DC converter.

And cut the tip of it. Leave the inverter on tho.

Splice the cables and feed the + and -.

Dont worry about getting polarity correct, because if you flipped it, the fan will spin backwards.


This is how i did it a fan on a router that kept overheating.


Becareful when you splice the wires. 12V hurts if you get zapped. And can kill you depending on amperage.



If your super lazy like i am, or your super scared to do this mod:

Plug and play make ya hollar? 🙂
I use my pumps on those during bleeding. So yes they can easily handle fan(s) with no problem.
 
Do you mean this: http://www.svc.com/3pinto4pinad.html ? OTOH if connecting to AC as the above seem to think, then the AC adapter above should work, but I have one and mine has only one ground pin - the one next to the +5V pin and even that one isn't connected to true earth ground as any drive power should be (necessary for draining off the static generated by the rotating mass). So if yours lacks one of the ground pins too, you'll have to make sure both grounds of whatever connector adapter you plug into it shorts the two grounds together or it may not work. Stupid that they assumed that the missing pin wouldn't be used...

I've plugged regular 12V fans in to 110V wall oulets before, surprisingly enough only about 1:6 actually light on fire, the rest just spark and melt, I was a little disappointed.
