Fan Corsair RS120 ARGB Computer case 12 cm Black

The Corsair RS120 ARGB is a 120 mm computer case fan that connects directly to the motherboard for simplified wiring and control. It supports a single 4-pin PWM connector for speed control and a single +5V ARGB connector for lighting, and is engineered to deliver a balance of airflow and static pressure suitable for use as a case fan or on radiators. The fan is finished in black and offers a rotational speed range from 420 to 2100 RPM with a maximum static pressure of 4.15 mmH2O.

Advantages

Direct-to-motherboard connection reduces the need for separate fan hubs and extra cabling while allowing unified control through compatible motherboard software such as ASUS Aura Sync, MSI Mystic Light Sync, ASRock RGB, and Gigabyte RGB Fusion. The blade geometry, enlarged blade radius within the housing, and Corsair AirGuide stator vanes are designed to optimize airflow efficiency and improve radiator fin coverage. A magnetic dome bearing reduces friction and mechanical noise, increasing durability and lowering acoustic output. PWM control with Zero RPM support enables quiet operation by allowing fans to stop at low loads.

Suitable for

• PC case cooling for gaming and workstation builds
• Radiator fans in liquid cooling loops
• Systems requiring ARGB lighting synced with motherboard software

How to use

Install the RS120 ARGB into your case or radiator mounting points using the supplied screws. Connect the 4-pin PWM cable to a motherboard fan header to enable speed control and Zero RPM functionality, and connect the +5V ARGB cable to a compatible motherboard ARGB header to control lighting via your motherboard software. Configure fan curves and lighting profiles in the motherboard utility to match your cooling and aesthetic preferences.

Recommendations

Use motherboard headers that support PWM and +5V ARGB to ensure full functionality. For radiator installations, position fans to maximize airflow through the radiator fins and enable PWM control for quiet and efficient operation. Avoid routing ARGB cables near high-interference components to maintain stable lighting control.
