Refrigerator Fan

I have a 320rs with the 8 cubic ft refrigerator. I was just reading my latest highways magazine and there was a question in it concerning a noisy refrigerator fan. I didn't know that there was a fan. I never hear any kind of fan. Where is it? Also they talked about adding an additional fan to vent the hot air. We camp in some very hot places and since the frig is in the slide, I would like to enhance the cooling anyway I can. Would someone out there please enlighten me.
Thanks

Turbs - where'd you get that middle one (on the inside). I've been looking for a battery operated little fan for inside - I read that it helps even out the coolness and allows the fridge to cycle less.

Thanks for the pictures. So, the 2 outside fans are venting hot air from the frig compartment. Where are they venting the air? I assume that these fans are 12V as well. Are they on a thermostat or do they run all the time or is there a switch. Did you notice a difference in the refrig temp when they are running?

No problem.
I mounted it by sticking two stove bolts through mounting flange of fan and the soldering an alligator clip on each one .
Then I just clip it on the fins .

The two outside fans blow hot air up the vent stack that comes out the roof.

They also only work if fridge is turned on.
But I installed a rocker switch to turn them off manually if its cooler outside.

Two ideas, not that I know where your fan is or if you have one.

While in the Tropics on our sailboat we used reflective insulation as a sun-shield. Although the refer was insulated heavily--built properly-- the insulation hung over the side made a significant difference. At times, we used the insulation for our windows even though they were bronze coated and reflective. Anything helped.

Today, our RV is sometimes enhanced by this sheeting on the inside of our windows which makes a huge difference in the 5w temp. You'll be able to feel the difference no matter the curtain style. And in Alaska this insulation blocked that 22+ hours of light in our bedroom. If it's hot inside the cabin your refer will work harder.

However, since we've got some space between the refer and the RV outside wall, with a bit of work this reflective insulation was added. I'm uncertain if we could measure the difference since it was done on day one, but it is bound to help while staying put in AZ, TX, etc, especially if the sun is on that side.

BTW, there are several model fans which are sold to mount between the wall and refer, exhausting hot air, but they take power.

Finally, we've always used a small 3v fan inside the refer to circulate the air. Measurements of the refer confirmed it's worth.

A product from Home Depot, Model # BP24010 Store SKU # 184928, might give you some ideas.

90 degree day with all the humidity you could handle.
Fridge was on 8 hours.

Most Radio Shacks stock these kinds of 12VDC cooling fans in a variety of sizes.

You can also get these kinds of units designed for supplemental Laptop cooling.

There was a problem with the fan being noisy when the fridge was on but it has been taken care of on later models. It created a high frequency whine that could be heard when sitting or in the kitchen. Adding an auxiliary fan is an idea especially when on high temperatures.

That the same problem many had. The computer fans are very quite, many on this site have used them. They help with the cooling also.

I even stuck an additional one in my converter to help keep it cool.
With a manual switch of course.

Turbs, I'm impressed my man, nice job. To be honest, I never really saw a need to add fans to the frig, but then again I have not ever had an issue with it. I can see where this would eliminate any chance of that happening. Thanks for the info.
