I purchased Four 5v 2" fans for my amp rack and I was wondering if anyone had any input on how I should power these?
Since they are 5v I dont think I can just hook them up to my 12v source, plus I guess I will need a relay or something so the fans only come on with the ingnition(remote).
Any set-up sugguestions would be greatly appreciated.
can I maybe just set them up in series or or parallel?
Betard, you have an unusual name. You need to get 12v relay from Radio Shack for $5 and hook it up to your HU's remote wire. Then use the relay to trigger your amp as well as the fans. Since they're only 5v, you will need to get a regulator. If that sounds complicated, then just purchase 12v - 6v adaptor from Radio Shack also. I think they cost around $10. You hook the fans up in parallel, as pos and neg to each fan.
in my experience, fans aren't too picky about voltage or current, within reason. Hook your fan up to a AAA battery (1.5V) and then a 9V battery. It'll probably work fine with either, or anywhere in between. My guess is that its designed for use in computer cases and computer power supplies only supply 12V and 5V DC power.
