I recently fitted 2 x 120mm computer cooling fans to my caravan fridge vents.
The difference is amazing – the temperature inside dropped about 5 degrees.
A brief overview
You will require a 12v supply to enable the fans to operate.
I included a thermostat so that the fans switch on/off automatically
but, i also included an on/off switch so that I can turn them
off manually if needed. (Conserve battery at night etc)
Here are a few photos to show how I did it – PoppyB – Administrator
