Hyper 212X is equipped with PWM Fan with red LEDs and provides the best airflow and static pressure to take the heat away. And four direct contact heat pipes with funnel-shaped aluminum fins provide the optimized CPU coolers for great performance. Moreover, the improved universal bracket designs ensure easy and worry-free installation on all platforms. Positioned at a 45-degree angle and surrounding the Heatpipe, each fin-blade features X-shaped vents that create areas of high and low air pressure, resulting in several controlled vortices. These small and chaotic turbulences produce strong gusts that reduce overall airflow but improve airflow where it matters the most – next to the heat pipes. Funnel-shaped aluminum fins and a series of perforated dimples guide the airflow towards the heat pipes. Specially designed X-Vents, that act similar to tiny airplane wings and prevent deadspots behind and between heat pipes. 4 Continuous Direct Contact Heatpipes create a gap-less contact surface for unmatched cooling efficiency. It is fast and easy to install and extremely reliable, our famous X-Bracket mounting system is compatible with all current sockets. The POM bearing is coated with Polyoxymethylene material. This type of material is ideal for precision parts requiring high stiffness and provides consistently lower friction levels than traditional bearings. This product has no warranty.
