12 volt cpu fan in fridge
Hello.
I know its possible to hook a 12 volt cpu fan to the inside fridge fins for better cooling as I saw it on youtube, But where would i to hook the power so the fan runs inside the fridge, and maybe only when the fridge is actually in a cool cycle. I have the norcold 1210. I thought of the battery type but they take up space. Any and all ideas.

I went outside behind the frig and found where they drilled a hole for wires into the frig. I drilled a small hole into the frig and used white gorilla tape over it.

Or you can hook it up to your light.

Or run the wires down through the drain tube to the outside.

My Norcold 2118 has a 12V circulating fan in the top of the fridge compartment. Not sure about yours. I connected a 12V fan there to blow across the fins. Much better cooling now.

Where did you find the power for the fan?

There are two common sources of 12V power for a fan. Older refers had 12V available at the light when the door was closed. It was easy to tap in there. Newer models kill the power to the light when the door closes. In that case, run the wires through the drain tube and tie into the 12V supply on the circuit board.

I think Butchy is talking about the thermostatically controlled exterior fan(s) behind the fridge that circulate air over the exterior cooling fins. Even so … there is 12 VDC at the bottom of the exterior controls … that's where the fridge and fans get the OEM power. This is an ARP install I did, but it shows the OEM 12 VDC source.

Ok. thanks for the info. Were trying to get more cooling to the bottom of the fridge. I'm showing 44° on the bottom and 39° at the top of the box. freezer is nice at 8°. The thermistor is almost to the top on the 2nd fin so there is no more adjustment. We full time and florida is hot right now and i have 2 fans in the back and they work cycling on and off so i dont think i need another fan there.

I put a 110 fan behind the frig and used a timer to run it during the hotter daylight hours and then cut off at night. Seems to help keep the fridge cold. I have a small battery operated fan inside that keeps air moving.

Other members have given 2 or 3 options on getting 12 VDC power into your fridge cabinet. There are different choices of internal fans found on the internet … some with fancy blue lights. We've always used the battery powered squirrel cage fridge fan ($15) as it moves more air than the bladed one. The batteries last several weeks. I guess I don't have issue with it taking up space as it is about the size of a can of pop or a small container of sour cream … hardly an issue.

Yea, Normally i would not worry about the fan that sits on the shelf and as you said is a pop can size but we full time and i need all the space i can find. i saw on youtube a fan attached directly to the fridge fins (The fins inside the box) and was wondering where to hook up power as the video didn't show that part. I will probably run a wire out the drain tube as others have stated but was wondering if there was a 12 volt supply inside the fridge itself.

Refrigerator fan
Smart RV Products sells the 12 volt fan unit that attaches in front of the coils and gives great instructions on installation and power connection for the refrigerator model. Our wiring connected to the incoming power to the refrigerator light.
