Fridge/freezer-Instaling computer fan

Suck it out works for me! also If you create a lower pressure it also makes it slightly cooler.

Cheers.

I fitted one to my fridge yesterday.It blows towards the motor, I chose that way as I could direct the straight at the compressor/motor. Drawing air away from the motor also draws air from the surrounding space

have a look at this post on anoither forum.....a lot of info.

Fridge fans feedback
by Ole Mate on Tue Aug 18, 2009 11:00 pm

I know that there has been some discussion on this topic before, but I will post this for those who are undecided as to weather it is worth fitting them.
Our 3way fridge had been checked OK, it is well insulated, but being in a poptop can not be vented through the roof. It was always set on the maximum setting, and still struggled to keep cold.
I would put a couple of cans in the freezer an hour before 'happy hour' in the hope of getting something that resembled a cold beer. I had to do something, so I tried fitting a couple of fans.

One fan is mounted on the top vent, the other on an angled bracket so it forces air up into the cooling fins. They are wired in series, so they only use about 110 mA, and only the top one can be heard, from outside, about 20 cm away.

Last weekend we used it for the first time.
Before we adjusted the temperature setting, the food was starting to freeze, not just in the freezer, but in the fridge. We turned the setting down to about half.
The days were hot, but the evenings were cool, so they shut down at night.

My 'happy hour' beers were starting to turn to ice by the time I got to them.

2 x 80cm computer fans. $3.79 ea.
1 x 50deg Thermostat Switch. $4.95
1 x Toggle switch. $3.00
Some wire, zip ties, silastic, crimp joiners, etc that I had in my 'useful box'.

We are more than happy with the result.

Cheers

Jimmy, Take a look at thread 74817 Waeco Fridge Modifications.

I have a computer fan blowing across my compressor which is in a 1mtr long timber box in my GQ

Slightly off the topic - a little .

I have recently installed a 40mm centrigugal fan on the wall between the main compartment of the Waeco CF50 and the smaller dairy box --
The fan sucks air from the main compartment and blows it across and into the smaller one - this has dramatically improved the chilliness of that smaller compartment without any apparent detriment to the main area --
In degree terms a drop of 5 to 6 degrees C has been achieved -
Cost $4.60 and $7.70 for a new LED "festoon" bulb as with the fan running constantly the standard filament bulb didn't work ..

Cheers
