Power a fan via usb or other non standard method?

post #1 of 5
Thread Starter 
Hi all,

Right here is the situation, we have digital sinage at work and the screens are powered by a small pc that has 6 USB ports on it, the problem is, it's all covered up with a metal frame. Now there are vent slots in the frame but I still think there is a lot of heat in there. So my suggestion is to put some PC fans on top of the cover (we will have to cut holes obviously), now I would need to power the fans but as you know fans run at 12v and usb is 5v. So my question is....

Does anyone know if there is a USB to fan converter, or a 12v converter that I can power the fans with?

Thanks in advance

Why not just get power cable extenders and use your computer's PSU to power the fans?

You could of course buy another psu to power them also!

Because it's a sealed box, and the power that goes to the pc is a laptop power cable.

Already thought of powering them via a psu in the case but not an option as there is very little space in there.

USB is 5v, you can run fans but they will not work at full if you have 12v fans.
I think you can wire by yourself i mean remake fan connector into usb one
USB design

EDIT: dunno if it will work or damage your fan...

Ive spliced USB to fan connectors in the past and ive always been lucky and had no problems but, i have a very cavalier attitude!

Dont know if THIS will be of any help:
