additional fans for fridge

Yep top vent easy way to fit them is to fit a couple of 12v computer type fans to the top vent with cable ties.

I've fitted them to a couple of caravans in the past, first one with a thermal switch in line, second time I just fitted a switch in line and just turned them on on hot days and off at night.

There's a fitting article here

GOOGLEing on "fridge cooling fan" will retrieve plenty of other related discussion (some of it needing to be treated with caution!)

 

Inexpensive computer fans are often used, but choosing a kit would be simpler (and, with any luck, the fan-units will be more weather resistant). CAK Tanks market single- and twin-fan kits

and they are also available here

(I've extracted the above from an earlier forum thread. The links still work, but I haven't checked if the adverts are still current.)

just a thought but make sure before you purchase a kit that there is room enough behind grill to fit it.

Top vent , they suck hot air out

 

They are better in the top as Mickt has stated.

 

If you place in the bottom then you are creating turbulance in the air and could affect the gas burner. Also you would be creating positive pressure and if there was any leaks to the inside of the motorhome you could push fumes into the habitation area.

 

You also probably only need one fan and not two but seems most like to fit two.

Interesting...if your sure one enough you can get a PC fan for less then a fiver, a switch and fuse and a pretty easy DIY job. £35 for a twin fan set up a bit much, I had one and it fell to bits when I tried to move it to 3rd van

There's a "top or bottom" discussion here:

 

http://www.touringandtenting.com/forums/index.php?/topic/38093-fridge-cooling-fans/

 

Me, I would have thought that fitting the fan(s) behind the upper ventilation grille is the obvious thing to do. These appliances cool by air rising naturally from lower to upper grille and the fan(s) just augment that process.

 

There's another installation article here

relating to a more DIY approach using Maplin-sourced bits.
