The latter type of fan seems to have more proponents who say the extra air movement helps the system cool better. To me, a fan inside the fridge doesn't seem like it would make much difference.
Mike, I've used both kinds & each works very well for its purpose. The exterior fan passes air over the cooling coils, which aids in removing heat that the 'coolant' builds up. The little internal fans circulate the air inside the fridge thus avoiding 'pooling' of cold air in lower areas or where several items are otherwise blocking circulation. When I didn't have the interior fan I've had eggs/lettuce and such actually freeze on bottom of my fridge while milk on the upper shelf next to the tiny freezer was just barely cold enough to keep from spoiling. The little fan keeps air circulating enough that a pretty even temp is maintained throughout the fridge. My little 'FridgeMate' battery
operated finally 'gave up the ghost' so I guess I'll hafta look for a new one.
I have considerable experience with 2 older Dometic 3-way fridges, a 211 in my '85 Scamp
& an RM2200A in my '87 Skamper pop-up truck camper. Except for the model #'s they appear identical inside & the 'operating mechanism' from the rear. I always use either 110vAC or propane
to 'cool' the fridge before departing on a trip, & the 12vDC while underway. The P/U camper is hauled on a Ford F-250 Diesel P/U that has 2 batteries & a huge capacity alternator so I've never had any problem with 12v operation. I've not used the Scamp
yet for any extended trip but my Toyota Tacoma TV is wired so that it charges the trailer battery
while underway, & on short trips to the lake or deer camp I've not noticed any undue loss of battery
