Review on Upgr8 Universal High Performance 12V Slim Electric Cooling 🌀 Radiator Fan: 7 Inch, Blue – Complete Kit for Efficient Cooling by Paul Wilson

I am very satisfied with the quality of this product (12 inch radiator fan). I use it in a vent in my solar shed to push hot air out. I reversed the blades and fan wire polarity to make it a thrust fan and it was very easy to do. I also use a small motor controller to set fan speed and current draw. On the fastest setting, you definitely know the wind is very strong. I usually set my controller so that the fan draws about 3 tenths of an amp most of the time. This seems like a good compromise between airflow and current draw in my solar project. I also use a 12 volt timer to give myself a chance to suck in the coolest air for about 20 minutes before sunrise, then turn it off until 9:20am where it turns back on until 5pm. I recommend this fan for this solar application.
