ok Im trying to use a computer fan in my room. and i know that you can usea 12v dc converter or old power supply.
I have the computer power supply, but it requires a on off switched to be wired also, mine broke. is there way around this? right now i jsut have an entire old comp inthere but the only way to have the power supply on is to have it plugged into the mother board and use that on off switch on the tower.
how can i avoid this and jsut use a power supply?
