If the PS4 again runs a little longer ...

If the PS4 again runs a little longer, you can certainly times think about the cooling. There are practical clip-on coolers like this one from DBPOWER for this purpose. It is delivered together with a cable for power supply.

The principle is very simple: you put the device that contains 5 fans, just the back of the PS4 on. That's very fit, has the same color and looks like it would belong to the console. For the power supply you need a USB connection. Of course you can use the Add-mounted on the front of the PS4 USB connection, but in my view speak three things about it. One would have namely the cable up lead on the console, otherwise it is not sufficient in length to. In addition, the operation of the fan would burden the console even more, and the USB port would no longer be available for the loading of the controller are available. I've settled for me so that I have the power of the fan simply solved through a power bank.

The fan is complete, orderly processes of simple plastic, accurately and easily. However, fan power can also be a little stronger, even when operating in turbo mode. Overall, this is but a practical and affordable accessory that adds value during prolonged operation of the console.
