The Nvidia Shield 2019 Tube 'Airflow' case is designed to increase airflow into the device and expel the hot air, keeping the device cooler and reducing the need for the built-in cooling fan to run at high capacity. This minimises annoying noise from the cooler, even with prolonged use and maximum performance settings. The case can still get hot, but the noise level is significantly reduced. The product includes a *.stl file, different from the one in the images, with smaller align pins for seamless installation.
