Computer Fan to Car Battery?

Question

I have a car amplifier that chronically overheats, I was thinking about buying a hard drive cooler to mount to it but later thought of hooking a few case fans to it instead.

Since computers run off 12v DC is it possible to hook the computer fans straight to my auxiliary deep cycle 85A car battery?

thanks,

Answer 1

That will work fine. I have had that setup for about 10 years now.. Works great

Straight to the battery

Answer 2

Ya,it will work fine,i did the same thing. Just remember to hook the positive wire to the remote wire,so it will turn on and off with the amp.

Answer 3

If your amp overheats??   It is wired wrong..

Answer 4

this is what you need, follow the link http://www.sonicelectronix.com/cat_i439_...

Answer 5

Inside the computer it is almost exactly 12V.  On a car the voltage varies from 12 v to 15 v.  If you get a decent quality fan it should survive that much.

But either way it would NOT cause any other damage if the fan burned out.  So give it a try.

If the fan burns out, then you can try a LM7812 voltage regulator.  For your fan, you don't even need the capacitors.
