CORSAIR Fan - Rs Series Rs140 Max 140mm Single Pack

The Corsair RS140 MAX is a 140 mm (14 cm) black computer case fan designed for higher cooling performance. At 30 mm thickness—about 17% thicker than a standard fan—this model delivers increased airflow and static pressure, making it suitable for both case ventilation and radiator use. Built with glass fiber–reinforced liquid crystal polymer blades and Corsair AirGuide anti‑vortex stator vanes, the RS140 MAX focuses airflow and resists blade deformation while minimizing noise through a magnetic dome bearing and optimized design. The fan’s maximum speed is 1600 RPM with static pressure ranging from 0.2 mmH2O to 2.4 mmH2O.

Advantages

Thicker housing and larger blades provide stronger airflow and elevated static pressure compared with standard 25 mm fans, improving cooling performance on radiators and inside cases. The glass fiber–reinforced LCP blades maintain rigidity under load to prevent bending, ensuring consistent airflow. AirGuide anti‑vortex vanes concentrate the airflow into a tighter cone for more effective cooling, while the magnetic dome bearing reduces mechanical friction and acoustic noise, increasing longevity and delivering quieter operation at comparable airflow levels.

Suitable for

• Case cooling for mid‑tower and full‑tower PC builds
• Radiator mounting on all‑in‑one (AIO) liquid coolers and custom loops
• Systems requiring higher static pressure for dense radiators or tight fin stacks

How to use

Install the RS140 MAX in your PC case or on a radiator using standard 140 mm screw holes, ensuring correct airflow orientation for intake or exhaust as needed. Connect the fan to a compatible fan header on your motherboard or to a fan controller and configure fan curves in BIOS or software to balance cooling and acoustics. When mounted on radiators, align the AirGuide side toward the radiator to concentrate airflow through the fins.

Recommendations

For optimal results, use the RS140 MAX on radiators or locations where higher static pressure is required. Run the fan at lower RPMs to achieve comparable airflow to thinner fans while reducing noise; adjust fan curves to maintain target component temperatures. Regularly clean dust from the fan blades and radiator fins to preserve airflow and performance.
