Embracing Fans That Can Perform

Corsair has introduced the RS Max fans, designed for prominent performance in the commonly used 120mm and 140mm sizes. These fans feature a 30mm thickness and are equipped with curved Liquid Crystal Polymer (LCP) blades. This design aims to optimize airflow and cooling efficiency, making the RS Max fans a strong candidate for high-performance applications, particularly the 140mm variant. The new Corsair RS Max fans have been introduced to the market, featuring a unique 30mm thickness which is 5mm greater than most standard fans. This increased thickness significantly enhances static pressure, facilitating lower airflow reduction when passing through obstacles. This design characteristic suggests conceivable improvements in airflow performance under restrictive conditions.


Key Features

  • 30mm Thickness: An increase of 5mm over standard fan thickness allows for a larger fan blade, improving cooling performance.

  • PWM Controlled Speeds:

    • 120mm Fan:
      • Speed Range: 425 RPM to 2,000 RPM
      • Airflow: Up to 72 CFM
      • Static Pressure: 4.2mm-H2O
    • 140mm Fan:
      • Speed Range: 400 RPM to 1,600 RPM
      • Airflow: Up to 104 CFM
      • Static Pressure: 2.4mm-H2O
  • Premium Liquid Crystal Polymer Construction: Incredibly strong and durable with excellent rigidity, reducing blade vibration and increasing performance.

  • CORSAIR AirGuide Technology: Anti-vortex vanes direct airflow at your hottest components for concentrated cooling, suitable for intake, exhaust, or mounting on a radiator or heatsink.

  • Quiet Operation with Magnetic Dome Bearing: CORSAIR’s Magnetic Dome bearing minimizes noise and reduces friction for greater longevity.

  • Zero RPM Mode Support: Supports Zero RPM PWM signals to completely eliminate fan noise at low loads.


The Corsair RS120 Max fan operates at a maximum speed of 2000 RPM, delivering a maximum airflow of 122.33 cubic meters per hour. While this is lower than the 3000 RPM and airflow rates of the Phanteks T30, the RS120 Max is optimized for quieter operation at lower speeds, though actual noise levels and performance efficiency will need to be validated through comprehensive testing. The rotor design of the RS120 Max closely resembles that of the T30, indicating that any performance differences will likely stem from the fan’s other design elements rather than the rotor shape itself.

The 140mm variant, the RS140 Max, which caps at 1600 RPM and offers an airflow of 176.70 cubic meters per hour, is designed to be particularly competitive in the 140mm fan market, which is less saturated than the 120mm segment. The RS140 Max’s blade design, is consisting of seven widely spaced blades.

In terms of static pressure, the thicker profile of the RS140 Max is intended to improve performance on radiators and other high-resistance applications. The impellers of the RS140 Max are constructed from Liquid Crystal Polymer (LCP), known for its robust mechanical properties and stability, which may contribute to its performance. Both the RS120 Max and RS140 Max incorporate magnetic bearings, which are designed to reduce friction significantly, thereby lowering operational noise. This type of bearing is conducive to enhancing the longevity and reliability of the fans by minimizing wear and tear during operation.


Pricing for the Corsair RS Max fans varies by size and package options. The RS120 Max is priced at approximately 44 EUR for a single fan and 119 EUR for a pack of three in the Corsair European e-shop. Conversely, the RS140 Max costs about 55 EUR for a single unit and 94 EUR for a two-pack. The difference in bundling reflects typical usage scenarios: 140mm fans are often used in pairs for 280mm radiator setups in liquid cooling systems, whereas 120mm fans are commonly sold in threes, likely due to their frequent application in 360mm radiator configurations and in standard case setups where three fans are used either in the front or top positions.
