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

I took the larger fans and installed them in my 33ft Class C fan behind the fridge on the top shelf just above the coils. I've noticed that some people say they can't tell the airflow direction until the fans are plugged in, but mine was marked with the airflow direction and even the direction of rotation of the fan blades. My only problem was deciding exactly where to place the sensor. I was afraid the best way to do this would be to tie them to bobbins and dangle them between them. Hopefully the coils don't get too hot and melt the plastic insulation around the wire. When I installed them I was a bit concerned that I didn't see any fan speed indicators in automatic mode, but then I went back and re-read the reviews and saw that the fan speed was only displayed on the controller in manual mode. . I want them to show fan speed in both modes but it doesn't matter. They definitely create a lot of airflow and seem to have had a significant impact on how cool my fridge is. I haven't been able to test them in the extreme summer temperatures yet. I took off a few stars for very poor instructions and cheap controls and wiring. I expected more for the price but overall I like them and hope they last. If you buy these fans, I recommend reading all the reviews and watching the videos available on YouTube before installing them.
