    Icon32 Using computer fans on a 12v car system

    What do you have to do to be able to run computer fans and lighting accessories such as cold cathodes and LED's on your 12v car elictrical system? the fans and lights will be going into my amp rack, would i just wire em directly into the remote wire and a ground or would that be too much power for small fans? i just don't want them to blow up. any help would be appreciated, thanks.

    You could wire them into a dedicated relay/switch. That way, they would only draw as much pwr as they need. Check what voltage the motors run on first.

    you need to use a relay. the remote cannot supply the current needed for the fans, lights, and amp turn ons. the fans are 12vdc and should work fine in your car. the lights should do OK also.
