When ultra-high performance coolers demand additional performance, count on Blade Master PWM fan series to increase cooling efficiency. Blade Master offers a balance of high air pressure with balanced airflow and minimal noise levels. With the Blade Master family of 120mm, 92mm, and 80mm fans, unique wave-form blades create increased pressure that exceeds competitor fans at the same airflow. The highest air pressure allows Blade Master fans to blow directly through dense performance heat sinks for extreme cooling.




  • Well-balanced cooling performance with fan airflow, air pressure, and noise.
  • Wide PWM fan speed range between 600 - 2000 R.P.M.
  • Anti-vibration rubber pads around the edges to decrease noise.
  • Distinguished blade shape for airflow improvement.
