I own a cheap (no manufacturer name even) Red Bull merchandizing cooler that I use as a fermentation chamber for homebrewing beer. I have it wired with a Ranco digital thermostat for precision temperature control, and the fridge sees a very light duty cycle due to the fact that beer fermentation happens between 50 and 70F.
Last week, the condenser fan assembly (120x120x38mm, .2A @ 115V, 71CFM) started making a bad racket due to the bearings failing. I got a replacement fan assembly, but I got one with 105CFM airflow because that was the part I could easily locate in town. I checked the wiring to make sure it could sustain the extra amps, so I'm good on that end.
Here's my question:
Is upping the CFM of the condenser fan going to put undue stress on the compressor or any other part of the system, due to enhanced heat exchange at the condenser?
I read over the DIY rules for the site and I think this question is within-bounds, but I apologize in advance if I've actually broken the rules.
