Hey guys. Building a fridge and am going to wire my fan in parallel with the compressor so it only fires when cooling. Is that what y'all do or are there any creative wiring tricks out there?
Thanks

Why not just leave it running 24/7?
It takes almost zero power, not to mention its probably not good to start wiring other electronics in parallel into your condenser circuit.
All of the commercial coolers run the evaporator fan 100% of the time. My bev-Air cooler does that to keep the whole unit at a consistent temp.[/QUOTE
My TRUE GDM-49 does the same in a stock setup, but I power the entire unit off/on via controller. Huge electric savings to only have the PC fan running and does a great job.

Yea, OP should just wire the fan in so its always on. The benefits you gain from it always circulating the air will let you reduce how many times your compressor has to cycle on and off.

I'm not understanding your huge savings.
The stock TRUE GDM evaporator fan motor draws about 9 watts. If run continuously, that's 216 watt-hours/day or 6.48 kilowatt-hours/month. At $0.15 / kilowatt-hour, that's only 97 cents per month. Two fans can run for less than $2 per month.
I'm not sure which fan you're using but a quick search of 110v pc fans show anywhere from 6 to 13 watts.
Not meant to embarrass. I have a GDM-10 ferm chamber and a GDM-12 keg cooler. I ran the numbers a while back to see what that constant air circulation was costing me. In the end, I figured it was worth $2 a month. It's the compressor that draws over 90% of the power usage. When I'm not using the ferm chamber, I block the door open and let the evaporator fan dry everything out for a day and then I unplug it.Well that's embarrassing. Save a penny, earn a penny?
Even if my math was better, and I'd have run the numbers myself, I'd still have run it this way for simplicity. (had to make myself feel better somehow)
