Solar Fridge Vent Fans

Thanks all, I am going the 12v route.

I am also looking to install this on the inside of the refer vent IF, IF there is enough room. I have access to a 120v plug in which I can use a converter/adapter or find a 12v source in there some where.

Need to source the materials first.....

Here is a 120MM 12v fan which moves ~53 CFM very quietly and consumes 0.05 amps.

These computer fans vary widely in air moved for noise made and current consumed. The one above is a winner in all three and has a 6 year warranty.

I have a Nicro solar powered vent. Many years ago I cut the wire to the fan motor, removed the battery and the impeller, and covered the solar panel. It now has computer muffin fans pushing about 20x more air through it.

Before this Nicro vent became Noisy, the "c" sized Nicad battery would last for about 2 days in the shade, running all night too.

One can of course spend much less, or even salvage one from an old computer. but it might very well consume 3x the current, make twice the noise and move no more air.

3) Would I do better to install a 12v version instead

Yes.

For somebody who never boondocks I can't even understand the need in solar fan. Small 12V fan will draw less than 1A, you won't notice this on electrical bill.

If you don't boondock then the solar really doesn't make much sense, and probably will cost more. There is 12v available where you'll be putting the fan, so that's no issue. I got a couple of waterproof ones off Ebay for my fridge, still pretty cheap.

I bought a solar some years back and it froze up on me. the fan just quit working. so I went to computer fans.

I did not go solar in part from bad reviews a in part because everyone looks for shade in the summer.
