I replaced both fans with a bigger (120-mm) and more efficient fans. I found one at our local Fry's Electronic store, it's made by Silenx (Amazon link: Silenx Effizio 120mm) . Current draw is only listed as 0.09 amp, very quiet at 12 dBA, and moves a decent amount of air at 44 CFM airflow (more specs. pictured below). I also added a bypass switch wired in parallel with the thermostat switch, this way I can run both fans continuously if I wanted.
Before starting, make sure to disconnect the fridge from 120-volt and 12-volt power supply. Measure if a bigger fan(s) will fit the back of your fridge, the 120mm fan is a perfect fit on mine. Remove the stock fans. Install a bypass switch and a 12-volt inline fuse (optional). Install the new fans using L-brackets (see pictures of install below).
