Strange fan install

post #1 of 19
Thread Starter 
Hey guys,
I have 3 spare 80mm fans and I want to use them in a rather odd application,
I have a ps3,360 and my surround sound amp all in my tv cabinet, they are all in little compartments and it gets rather hot and stuffy in there, I have already had a ps3 and 360 die so I was thinking about mounting the fans on the back of the tv cabinet as exhaust fans, my only problem is how would I go about powering them, they are all molex,
Thank guys, not even sure if it's possible but if it is I know you guys are the people to ask.
Lex

Pick up or scrounge up a 12v power brick and splice in the wires. I've done it in a pinch.

Or use one of these.

You could make them plug into a wall outlet. You will need to convert the wall outlet 110v AC to 12v DC. You can do this with any universal AC/DC power adapter. You can even get a universal power adapter from Radio Shack that will have bare ends of wires that you can attach to a male molex connector by soldering the wires together. Then just plug in the female molex connector on the fan to the adapter and your all set!

edit: ^ I guess great minds think alike!

Yea you just need 12v. you could probably just find old power adapter from something and use that.

OR you can run them on 5v and plug it into the Ps3

Well a phone charger probably outputs 5v, but you might have something laying around that outputs 12v.

Well that says 9v, and actually you could run your fans at 9v so that would work.
