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 Jenny Hupke

I bought this because it's specifically for PS4 Pro. It looked great out of the box, but when I tried to install it the only way I could get it to stay behind was by moving it about half an inch to the left when viewed from the front, which it doesn't. Don't attach it to the PS4, it just lets it sit flush against your back. There are two long posts on the fan assembly that touch the PS4 case and prevent it from being slotted in and staying level. It seems to work well and definitely cools the device down, although any change in position will cause it to shift. I'm not satisfied, but it's not worth sending back.
