And to add to this, the stock fan motor, which still works, draws
~.27 amps.(even after I oiled the spindles.... ran quieter)  It spins
faster than the new motor. And IMO, pushes more air than the other CPU
fans. Of course YMMV. My choice in CPU fans may not be correct.
Regardless, given that in hot weather, the rear fan on my fridge seems
to run a lot, the lower draw motor with Dometic prop seems to be the
right thing for me.
