Review on ElecGear PS4 Auto Cooling Fan - USB Cooler with Temperature Sensor Control, Enhances Heat Exhaust for Playstation 4 CUH-1xxx by Patrick Stephani

The cooling system works much better than the Nyko intercooler! The system doesn't make any weird noises when I start it up again after playing for hours. The only thing I don't really like is that it doesn't fully snap into the console because it stays a little loose towards the top. The five-fan feature extends throughout the interior, keeping the entire console comfortably cool, which doesn't actually heat it up, so there's no risk of overheating.
