Muffin Fan Installation Norcold 1200LRIM

Looks like a good source for fans, especially since these are ball bearing, rather than sleeve bearing like most muffin fans. One thing I do wonder about and that is at 100 CFM each, that seams like way over kill. Just a small amount of air flow over cooling fins makes a huge difference in heat transfer. In looking at the set up, makes me wonder if one would be wise to wire them in pairs of 2 in series. That would cut the load in half, and probably still have plenty of flow. I'd bet tempted to run all 4 in series, although I'd fear if they would actually all run. I suppose if you are in really hot areas, you could use switches to switch back and forth between series and parallel. Then worst case, you would always have enough, but could save on your batteries when boondocking.
