A laptop cooling stand is a nice investment to keep your device cool while working. It is really useful when using any heavy application or playing a video game on your laptop. The fans in the stand–usually there are two to three of them–help cool the chassis by sending the air upward from down below. A laptop cooling stand comes with a USB-charging cable which, in our option, should be plugged into an external power supply and not to the laptop, if you can manage that, as it helps save the battery.
