Akasa Viper Black

Caution: toxic! Akasa now offers the successful case fan as the Viper Black, completely in black. This premium PWM fan is already known from the Venom CPU cooler, where it has proven its excellent performance and provides an optimal compromise between high cooling efficiency and low noise levels.

The optimized shape of the fan blades is primarily responsible for this. They are S-shaped, which, according to the manufacturer, allows for 30 percent more airflow at the same RPM compared to conventional fans. This, in turn, enables a reduction in speed to lower noise levels while maintaining the same airflow.

As a result of these efforts, the fan achieves a minimal noise level of practically inaudible 6.9 dB(A) at 600 RPM. However, via the PWM connection and a compatible motherboard, the fan can be accelerated up to 1,900 RPM, transporting an impressive 141 m³/h. This results in high flexibility, allowing the Black Viper to be used in systems ranging from silent to overclocking.

To further reduce noise, four rubber pins are included. These provide decoupling from the case or cooler, preventing vibration transmission.
