Review on ElecGear PS4 Cooling Fan and USB Hub: Smart Temperature Controlled Cooler & 5-Port USB 3.0 Adapter for Playstation 4 CUH-1xxx by George Ahmed

I was able to install the fan assembly on the back of the PS4 Pro with no problems, did it without seeing the front as I didn't want to remove the Playstation from its place and it snapped and plugged it into the USB port and everything was fine and it works and no noticeable fan noise. I suspect this helps keep the PS4 cool as the Playstation fans don't go into high speed mode which reduces the loud fan noise which reduces heat build up inside and gives the PS4 Pro a longer lifespan. Before PS5? The front USB ports are latched and all ports work except I don't have a USB 3 device to test this port by plugging a fan assembly into this port.
