Our 5er is parked much of the summer in a CG with the driver's side and Norcold 1210 fridge facing South. This means on a hot day it struggles to maintain a low temperature setting.
I've purchased a pair of 120mm Arctic case fans* to help the existing two noisy and puny fans with air circulation. I'll be using a thermo switch to turn them on and off plus wiring it to a dedicated 12VDC power source since the ARP control will be piggy backed off the fridge 12VDC control.
OK, with that said, and since I know others have done something similar, any preference as to whether these fans are bottom vent as blowers or top vent mounted as 'suckers'. I'm a little hesitant to use the top vent as there is a baffle covering about half of the opening.
