30 mm thick PC fans with high cooling performance in a double pack. The 30 mm thickness allows for larger fan blades and increased performance. 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 bearings. The thick CORSAIR RS140 MAX PWM fans maximize your cooling performance with two 30 mm thick fans featuring 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 reaching up to 1,600 RPM, delivering an airflow of 176.7 m³/h. The high-quality liquid crystal polymer construction ensures greater durability, rigidity, and fan performance. With CORSAIR AirGuide technology for focused 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 with the help of a PWM-capable motherboard, dynamically adjusting the fan speed to the operating conditions and minimizing unnecessary noise.
