The Nexus WaveAir is very suitable to get some fresh air in your case or get some hot air out of your case through a PCI slot opening. Hot air can build up between the PCI cards or above/below the video cards due to poor airflow. Suitable solutions are limited as you often do not have a lot of room in between PCI cards to have an extra cooling solution. Therefore, we developed the WaveAir which is an external solution for some extra active ventilation.
A standard 80 x 80 x 25mm case fan (Nexus 80mm Quiet Case Fan) fits inside the WaveAir. The shape of the WaveAir allows you to still connect cables to any of the surrounding PCI slots. And the wave air can be mounted two ways always; so you choose the side where the "bubble" goes.
The WaveAir is very effective for hot air extraction. So it is very effective as an extra exhaust for your case. This is convenient for small form factor cases that tend to really heat up at heavy usage because there is no room for an extra fan. If you have a PCI slot free, the WaveAir is a good choice.
