Fridge fans

What kind of fan does everyone have for their fridge? There are a couple on eBay like this one: Clicky. Or do you just use a simple battery powered box shaped one?

Also what is the purpose of this Valterra vent fan Here? It looks like it cools the back of the fridge. Is this really necessary?

Do any of these extend the life of the fridge?

had 'em both. the battery powered box never seemed to have enough muscle to make a difference. and i bought one similar to that in the link you provided. that was a bust as well. to begin with there was no constant 12v power source in my fridge (norcold N841) so i had to connect to 12v at the rear. ran the wire down the overflow tube, hooked it up and ran a number of tests (i posted about this a couple of years ago). long story short it turned out that the temps in the fridge actually rose with the fan clipped to the fins. i know...counter-intuitive ain't it?

not wanting to give up i've purchased a couple of small, very small, 12v fans and plan to wire-tie them to the bottom of the top shelf. the jury is still out.
