Computer PSU as power source for fans - Blu-ray Forum

Graphite · 03-14-2010, 01:00 AM

Here's the plan. Making an in-wall 5 shelf A/V rack. I want to get some fans put into each shelf, as to properly ventilate the heat out of the front open only shelving unit. The plan is to put 1 120mm fan per shelf, on the backside of the A/V rack to pull the air through the front, and out the back of the shelving unit.

Instead of buying a bunch of expensive "A/V coolers" from the net, i was going to attach a computer power supply unit to the shelving unit, and have it power my 5-120mm fans. Here comes the safety issues i'm having.

Using a paper-clip to fool the PSU to think that a motherboard is attached is simple...but is it safe? More than likely not. I'm hoping to find a permanent way to make my power supply a "safe" power source for my fan needs.

I'm hoping to find some help on this issue without tearing apart the power supply itself.

Thanks in advance!

Thanks Zippo. Don't know if the OP can use it, but I definitely can.
