Thermalright HR-22

HR-22 - 1120g, Silver The HR-22 is Thermalright’s super flagship cooler and accumulation of over 10 years of thermal innovation and technology. Design based on our new Directed Passive Airflow System, the HR-22 from the ground up was designed for 0 CPU Fan passive cooling.

What is DPAS?
DPAS is a comprehensive system of optimizations that takes total advantage of the natural airflow current within an enclosed PC-case. It is the accumulation of heatsink technology that works together to orchestrate PC-case airflow for maximum passive CPU heat dissipation.

Our Directed Passive Airflow System contains specific design guidelines for:
- Heatsink Fin Gap
- Heatsink Fin Shape and Patented Fin Through Holes
- Heatsink Structural Shape and X/Y Axis Displacement
- Thermalright Proprietary Airflow Tunnel Add-on Kit

With our Directed Passive Airflow system, the HR-22 can cool down the latest high-end AMD and Intel systems purely on case airflow generated by the system fans. And in fact letting PC users (sorry Mac!) eliminate the need for one of the noisiest component in your PC chassis (CPU FAN)! You think other sound/noise/silent optimized coolers have a chance?
