When on gas, does having vent fans running to disperse heat make it more or less effective at cooling ?

It depends on where the fans are. If they are at the top of the cavity behind the fridge and blowing air out then it makes the fridge and freezer work much betterWhen on gas, does having vent fans running to disperse heat make it more or less effective at cooling ?

Doesn't happen if you fit a temperature controller.Yes, but ONLY in hot weather. Accidently had ours on once in April & the freezer defrosted.

Let's see if I got this right......
In cooler climes the burner gases convect quite rapidly (cooler ambient air, warm exhaust) drawing heat from the fridge coolant.
In much warmer climes the ambient air temperature and exhaust gas temperature are much closer matched so the convection is much slower drawing less heat from the fridge coolant.
Having fans running draws air faster through the cavity area and faster moving air is always cooler than static air (think standing in front of a fan on a hot day) so the exhaust gas rises faster and draws more heat from the fridge coolant.
Physics dear boy, physics.
OK, so using that basis you don't actually need gas as the air will remove the heat by evaporation.Not sure about the moving air being colder than static air, the only reason the air from a fan feels cooler is because of evaporation from the skin and replacing air warmed by our body with cooler ambient air, unless of coursevthe ambient air temp is greater than 39.8°C.
A draught created by a fridge fan moves heated air from the fins of the coolant radiator and replaces it with cooler ambient air more efficiently than convection currents, think car radiator.
At least that's my attempt at the physics.....but I did fail A level physics

When I was at school A level was something you used to check if something was sloping.

I believe it is all down to latent heat folks... latent heat.
