A fair amount of heat is at the lower fins. Not sure, but a side fan
might hamper air movement up. It might also introduce warmer air from
higher up in Westy interior, to backside of refer.

Speaking of fans....

Check out this website: (click on fridge fans on LH side)

and this post

Seems model # A10-2710VP might do a better job than stock or computer
case fan. (moreover, 2 computer case fans)
