Review on ElecGear PS4 Pro Auto Cooling Fan - USB Cooler with Automatic Temperature Sensor Control, Radiator Heat Exhaust for PlayStation 4 Pro CUH-7xxx (Black) by Shawn Reiff

5 volt fans only need faster fans like 12 volts. Airflow is limited. also a buzzing sound. Upon arrival, one of the small fans was not working at all. found that none of the fans are protected. The fan rail is also loose. I used a small amount of 5 min epoxy and assembled all of the above. the system is now closed. Airflow is still disappointing.
