Refrigerator Cooling Fan (Outside)?
Been doing some searching but may not have hit the buzz word. I was looking for a how to on installing a cooling fan on the outside of the refrigerator (already have on inside it). Can anyone post...

Agreed on the poor installation methods by rv manufacturers.
Convection currents should be able to pull in enough air across the coils if installed properly with baffles and proper clearances and the fans only really required in super hot conditions on initial cool down or when the door is opened often with warm items plced within.
Those adding fans need to ensure that all the fan's flow is either evacuating the compartment above fridge, or forcing cooler air in from below, and not simply recirculating a high percentage of the air.
Meaning use a fan shroud for 100% air displacement instead of just aiming a fan in the general direction. Huge CFM numbers from a row of powerful fans is not needed. The 120mm 12v Noctua nf-f12 moves 53 CFM for just 0.05 amps, and can be slowed/ quietened even further for less amp draw by the 2 different ' low noise adapters', they provide with the fan. One has been attached to my danfoss's condenser for nearly 5 years. Awesome fan. They have industrial versions that are higher rpm and IP rated against water and dust ingress.
Don't get just any 12v computer fan. They vary widely in amperage consumed for air moved and noise made. Some are loud wasteful amp ******, others are whisper quiet, and can move all the air required for a fraction of the electrical consumption.
