After many years of "fridge frustration" I seem to have finally got the temps to good cold levels with two large internal fans running 24/7 and outside fans running as required when the ambient goes over 25c ish.
I now wish to refine the internal fan control speed function as sometimes the fridge gets too cold overnight and Mrs Vans (ears like radar) can hear the fans running overnight.
My goal is to have temp control set @ eg 4c and the fans run at a required speed to achieve that and once achieved "slow down" to reduce the noise and not overcool the fridge which will increase gas usage. The other desire is a "night mode" so the fans run as slow as possible to minimise the noise and not turn the fridge into a freezer overnight.
I may be over thinking it and a temp controller with varying fan speed will do the job but I can't seem to find an off the shelf controller with variable speed control. I have an option to use an Arduino unit which my son reliably informs me will do all I need (including the outside fans of required) but will need some tweaking via USB when we are on the road and I am less keen on that. The other option is a Raspberry Pie with BT interface but my current coding skills are nil so that would be a challenge.
So simply put... anyone used / built a variable speed controller or set up a Pie / Arduino unit to do the job?
Thanks in advance.

. Which controller did you end up with please? Our fan is in the same place with an additional one on the second shelf down blowing down. This has made the lower part of the fridge considerably cooler and as you said a long time ago who cares about the gas consumption as long as we have cold beer
