Caution: Toxic!

After the Apache successfully ventured into the realm of high-end fans, Akasa expands its premium PWM fan series with the Viper. This fan is already known from the Venom CPU cooler, where it has demonstrated its outstanding performance and provides an optimal compromise between high cooling efficiency and low noise levels.

The key to this is the optimized shape of the fan blades. They are S-shaped, allowing for more air to be moved at the same RPM. This, in turn, enables a reduction in speed, which helps to lower noise levels while maintaining the same airflow.

As a result of these efforts, the Viper achieves a minimal noise level of 12.5 dB(A) at 600 RPM. However, via the PWM connection and a compatible motherboard, the fan can be accelerated up to 1,600 RPM, moving an impressive 187 m³/h. This provides high flexibility, allowing the Viper to be used in systems ranging from silent to overclocking setups.

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