There is no information on what size laptops the N8 will fit, but the official dimensions are 380 x 277.8 x 54.8mm. So I’m assuming you will be able to fit at least a 15-inch laptop on the N8. The top of the N8 is made of aluminum, which will help dissipate heat from your laptop.
In the center of the N8 there are 2 large openings for the 2 140mm cooling fans. These fans will help cool down your laptop. The other part of the N8 is plastic and helps put the cooler up on a angle for good airflow.
Looking at left side of the N8 you can see how it is put up on an angle. There are 3 USB ports on this side.
On the right side there is a single USB port, which is the USB in port and next to it is the power button for the fans. You can also see how thick the aluminum plate on the top of the cooler is.
Flipping the cooler over you can see the 2 140mm fans. There are also 4 rubber feet that will keep the N8 from moving around on your desk.
