Review on 💦 TITAN- TTC-SC20: IP55 Waterproof Double Rack Mount Ventilation Cooling Fan with Timer and Speed Controller - 12V DC, 140mm by Talapon Blackburn

I used this fan setting to increase airflow for my fridge on wheels. We live in our RV all the time and find that our fridge struggles to keep our food cold enough for just a few days during the summer months. So I installed these fans to blow air over the condenser coils and can see a monumental 5-6x increase in airflow. This should make a big difference in fridge efficiency at this time of year. It wasn't difficult to set up the controller, I just remembered that the black power wire is ground, the red power wire is +. I couldn't find this information in the manual. Just 24 hours after installation, the ice is hard again and the food is really cold again. 48 hours after installation I'm considering lowering the thermostat setting even in 100 degree weather. Best update I've done.Ven
