30 mm thick PC fan with high cooling performance. The 30 mm thickness with larger fan blades provides more power. PWM-controlled speed up to 1,600 RPM. Very high static pressure of 2.4 mm-H2O. High-quality liquid crystal polymer construction. CORSAIR AirGuide technology for concentrated cooling. Quiet operation with magnetic levitation bearing. The thick CORSAIR RS140 MAX PWM fan maximizes your cooling performance with a 30 mm thick fan and enlarged fan blades. The increased thickness results in a high static pressure of 2.4 mm-H2O, efficiently directing air through PC radiators. Precise speed control is enabled by PWM-controlled speeds that reach up to 1,600 RPM and deliver an airflow of 176.7 m³/h. The high-quality liquid crystal polymer construction ensures a longer lifespan, rigidity, and fan performance. With CORSAIR AirGuide technology to focus airflow and a magnetic levitation bearing for exceptionally quiet operation, the RS140 MAX is ideal for high-performance systems. PWM connection. This case fan allows for speed control via pulse width modulation using a PWM-capable motherboard, dynamically adjusting the fan speed to the operating conditions and minimizing unnecessary noise.
