Audiobahnaholic Posted June 12, 2007 Report Share Posted June 12, 2007 Okay I am looking to purchase some computer fans to cool my amplifier in my car. The ones I am looking at have the 3 pin connection, I was wondering how I hook that up to a power and ground lead so that I can wire them off a toggle in the car? How do I do it?

Cdizzle Posted June 13, 2007 Report Share Posted June 13, 2007 On computer cathodes, when you hook them up in your car you cut the wires yellow and black, the yellow wire is positive. I dont know if it is the same for fans, but I am pretty sure that it is. also make sure you fuse the wire to the power cause if you dont you will no longer have a working fan.

BassJunkie Posted June 13, 2007 Report Share Posted June 13, 2007 Yellow is 12V, red is 5V, and black is ground. Just an idea, run your remote wire to a relay, and use the relay to turn on the fans and the amp Quote 1986 C20 Suburban 9 American Bass XFL 15's B2 M1MKII 14v XS Power Batteries Maxwell Caps Acoustical energy is free.

What happens if you hook the wire up into the same terminal on the amp as your rem, like, why do you need a relay? Quote Damn Thiefs Link to comment Share on other sites More sharing options...
BassJunkie Posted June 13, 2007 Report Share Posted June 13, 2007 Well depends, I dk how much power is comming from the remote wire, I don't think its 12 volts, you need 12 volts to power those fans.

Dale Posted June 28, 2007 Report Share Posted June 28, 2007 i would guess that those are separate power rails. 12 and 5 volts like bassJunkie suggested. For a vehicle environment, only use the 12 volt rail. you may damage the 5V if you run 12V thru it. unless, of course, you step it down.....which is just not practical.
