Computer fans

I was thinking about installing a computer fan in my grow room and i was just wondering how would you connect the wiring to make the fan work, without plugging it into an actual computer (im crap at electrical stuff)

A computer fan is so small I doubt it would do any good. If you want ventilation get a bathroox exhaust from one of the big box hardware stores like Lowes or HD. If you need help wiring let me know.

It answers your question perfectly.

cheers guys. i did try and search a thread so i didnt waste people's time but couldnt find anything.

Hey, luckily my computer is right next my cupboard, and i've hooked a computer fan up check out the pic..(seen on the right)I'm only using it for when they're small, I've got a 6" for when they're larger..
As for wiring it up, I couldnt imagine wiring it up to the mains as they're designed to run off a tiny amount of power..
