Fan Akasa SOHO AR14 14 cm Black 600-1800 RPM Hydro Dynamic Bearing

The Akasa SOHO AR14 is a 140 mm PWM cooling fan designed for PC cases, heatsinks and radiators. It runs between 600 and 1800 RPM, uses a Hydro Dynamic (MHD) bearing for extended life and reduced noise, and features 14 individually addressable RGB LEDs across three light-ring zones with motherboard sync support for major RGB ecosystems.

Advantages

Advanced sickle-style blades and optimized rotor geometry provide high airflow and static pressure while minimising turbulence. The MHD bearing increases lubrication capacity for smoother rotation and a rated life of up to 40,000 hours. Intelligent PWM speed control keeps noise low at light loads and allows full performance when required. A reinforced frame with corner anti-vibration mounts reduces transmitted vibrations for quieter operation. The addressable RGB system offers over 16.8 million colour combinations and is certified for sync with popular motherboard RGB software.

Suitable for

• Case ventilation for gaming and workstation PCs
• CPU heatsinks requiring 140 mm fans
• Radiator cooling in liquid-cooled systems
• Systems where low noise and vibration damping are important

How to use

Install the fan in your case, radiator or heatsink using the included screws or vibration mounts. Connect the 4-pin PWM power cable to a motherboard fan header that supports PWM control to enable automatic speed regulation. Connect the addressable RGB cable to a compatible aRGB header on your motherboard or controller to manage lighting. Ensure airflow orientation matches your cooling plan (intake or exhaust) and verify secure mounting to minimise vibration transfer.

Recommendations

For balanced cooling and low noise, use PWM control and set fan curves in your motherboard software. When installing on radiators, mount the fans to optimise push or pull configurations per radiator design. Periodically check and clean the fan blades and frame to maintain performance.
