Air cooler Sharkoon A40 12 cm Black 500-1800 RPM 121.55 m³/h

The Sharkoon A40 is a 12 cm air cooler engineered for efficient case ventilation and steady fan performance. With a fan speed range from 500 to 1800 RPM, it balances cooling capacity and acoustic comfort. The cooler delivers an airflow of 121.55 m³/h and a maximum static pressure of 2.9 mmH2O, while its fluid dynamic bearing supports longer lifespan and reduced noise during operation.

Advantages

The Sharkoon A40 provides consistent airflow for improved heat dissipation, suitable for most mid-tower and compact desktop systems. The fluid dynamic bearing minimizes friction and operational noise, extending service life compared with sleeve bearings. A wide RPM range enables adaptive cooling: lower speeds for quiet idle periods and higher speeds to handle increased thermal loads.

Suitable for

• General desktop case ventilation in home and office PCs
• Cooling airflows for mid-tower and compact PC builds
• Replacement or upgrade for existing 120–130 mm case fans
• Systems requiring a balance between airflow and low noise

How to use

Install the fan in a compatible case fan mount or radiator bracket sized for 120 mm fans. Ensure correct orientation for intake or exhaust according to system airflow design. Connect the fan to a motherboard header or fan controller that supports the chosen voltage or PWM control method. Verify secure mounting and cable routing to prevent contact with other components or fan blades. After installation, monitor fan speed and system temperatures to confirm expected performance.

Recommendations

Use lower RPM settings during light workloads to minimize noise and increase bearing life, and allow temporary higher RPM during gaming or heavy processing to maintain optimal temperatures. Periodically check and clean the fan blades and surrounding filters to prevent dust buildup that can reduce airflow and increase noise.
