## Summary description

The Akasa Viper 12 cm fan features a black design with a rotational speed range of 600 to 1900 RPM. It provides a maximum air pressure of 2.98 mmH2O and operates quietly with a hydraulic bearing type. Ideal for enhancing airflow in your computer case, it ensures efficient cooling and optimal performance.

## Long description

The Akasa Viper 12 cm Black is a high-performance 120 mm case fan designed to increase airflow and improve cooling in computer cases or on heatsinks. It features S-FLOW blade geometry that delivers approximately 30% more airflow than a standard fan at the same speed, PWM automatic speed control and a Hydro Dynamic Bearing (HDB) for extended service life and reduced noise. The fan operates within a rotational speed range of 600–1900 RPM and offers a maximum static pressure of 2.98 mmH2O.
Advantages
S-FLOW blade design increases airflow efficiency while PWM control adjusts fan speed automatically to balance cooling and acoustic performance. The Hydro Dynamic Bearing maintains constant lubrication using a dynamic pressure field and anti-leak seal, which extends operational life (up to 50,000 hours as stated by the manufacturer) and lowers operational noise. The focused airflow pattern provides improved “blind-spot” cooling for components that need targeted ventilation.
Suitable for
Case ventilation to improve internal airflow
Supplementary cooling for heatsinks or radiators
Replacement or upgrade of standard 120 mm fans
Key specifications

How to use
Install the Akasa Viper fan in a standard 120 mm mounting location in your PC case or attach it to a compatible heatsink or radiator using the appropriate screws or mounting hardware. Connect the fan to a PWM-capable motherboard header or a compatible fan controller to allow automatic speed regulation. Ensure the airflow direction matches your intended cooling configuration (intake or exhaust).
Usage recommendations
Mount the fan securely to avoid vibration noise, keep dust filters clean to preserve airflow, and connect to a PWM header to benefit from automatic speed control and quieter operation when full cooling power is not required.
