CORSAIR RS120 MAX 120mm PWM Thick Fans

Instruction Manual

Introduction

The CORSAIR RS120 MAX PWM Thick Fans are engineered to maximize cooling performance in high-performance systems. Featuring a 30mm thick design, Liquid Crystal Polymer construction, and CORSAIR AirGuide Technology, these fans deliver high static pressure and efficient airflow with quiet operation. This manual provides essential information for the proper installation, operation, and maintenance of your RS120 MAX fans.

Setup

Follow these steps for proper installation of your CORSAIR RS120 MAX fans:

  1. Prepare Mounting Location: Identify the desired mounting location in your PC case or on a radiator. Ensure sufficient clearance for the 30mm thick fan.
  2. Secure Fans: Use the provided mounting screws to firmly attach the fans to your case or radiator. Ensure the fan is oriented correctly for desired airflow (intake or exhaust).
  3. Connect Power: Connect the 4-pin PWM connector from each fan to an available 4-pin fan header on your motherboard or fan controller.
  4. Cable Management: Route cables neatly to avoid interference with other components and to maintain good airflow within the case.

Operating

The CORSAIR RS120 MAX fans are designed for optimal performance and quiet operation:

  • PWM Control: The 4-pin PWM header allows for precise control of fan speeds, ranging up to 2,000 RPM. This enables dynamic adjustment of airflow based on system temperature, balancing cooling and noise levels.
  • High Static Pressure: With an increased thickness of 30mm, these fans generate a high static pressure of 4.2mm-H2O. This makes them ideal for pushing air through restrictive environments such as high-density radiators.
  • AirFlow: The fans deliver up to 72 CFM of airflow, ensuring efficient heat dissipation from your components.
  • CORSAIR AirGuide Technology: Anti-vortex vanes concentrate airflow directly at your hottest components, providing targeted and effective cooling.
  • Magnetic Dome Bearing: This advanced bearing design minimizes friction and mechanical noise, contributing to quiet operation and extended fan longevity.

Maintenance

Regular maintenance ensures optimal performance and longevity of your fans:

  • Dust Removal: Periodically clean dust from the fan blades and frame using compressed air or a soft brush. Ensure the fan is powered off before cleaning.
  • Inspect Connections: Occasionally check that all 4-pin PWM connections are secure.
  • Avoid Lubrication: The Magnetic Dome bearing is self-lubricating and does not require additional oil or grease.

Troubleshooting

If you encounter issues with your CORSAIR RS120 MAX fans, consider the following:

  • Fan Not Spinning:
    • Check if the 4-pin PWM cable is securely connected to the motherboard or fan controller.
    • Verify that the fan header on the motherboard is enabled in the BIOS/UEFI settings.
    • Ensure the power supply is providing adequate power to the system.
  • Excessive Noise:
    • Check for any cables or obstructions interfering with the fan blades.
    • Ensure the fan is securely mounted and not vibrating against the case or radiator.
    • Adjust fan speed settings in your motherboard's BIOS/UEFI or fan control software to a lower RPM.
  • Poor Cooling Performance:
    • Verify correct fan orientation for optimal airflow (e.g., intake for fresh air, exhaust for hot air).
    • Clean any dust buildup on the fan blades or radiator fins.
    • Ensure there are no obstructions blocking airflow paths within the case.
