12 Volt fan question

[DuluthMedic]

I'd like to run 3 12 volt computer fans in my ice house. There called "muffin fans." I'd like to slow or control the speed of the fan. They are just too loud. I was told I needed a rheostat to slow the speed of the fan. I was also told to try an old switch from a car dashboard heater. They will all be hooked up to a boat battery. Any ideas?...I know I'm not the only one with these fans. Please help!

Maybe you can just try a standard dimmer switch from the hardware store. Like the one in the dining room.

You'd need the switch, resistor, and harness from the car.

The dimmer switch would be easier.

Surface tension are u talking about the dimmer switch from a car or truck?

Dimer Switch as in, "Like the one in the dining room."

What I have used is the dimmer switch for the dash lights in a car. These will work for any low amperage device.

Although I never thought of using a light dimmer switch for a house, but being I am a mechanic I had car parts readilly available for cheap or free!

You could use the 120mm fans. newegg has an assortment, many of which have a db rating of 25 or less--whisper quiet. They run at lower RPM but move a lot of air.

Thanks guys..i'v got 3 fans already they are .8. I will try a truck/car dimmer. I'll let ya know how that works.

Picked up the rheostat, and the watts are to small...she got hot! Anyway I'm going with computer fan speed controllers. Duh! Why didn't I think of that!
