Fan Corsair RS120 ARGB 12 cm White 420-2100 RPM

The Corsair RS120 ARGB is a 120 mm white case fan designed for efficient cooling in PC builds. It connects directly to the motherboard using one 4-pin PWM connector and one +5V ARGB connector, supporting synchronized lighting control via ASUS Aura Sync, MSI Mystic Light, ASRock RGB and Gigabyte RGB Fusion. The fan is engineered for balanced airflow and static pressure, making it suitable as a radiator fan or a chassis intake/exhaust fan.

Advantages

Direct-to-motherboard connection reduces cable clutter by eliminating external hubs and allows full control of fan speed and ARGB lighting from motherboard software. The RS120 ARGB features an optimized blade shape, a housing that maximizes blade radius for its size, and Corsair AirGuide stator vanes to focus exhaust airflow for improved radiator coverage and heat dissipation. A magnetic dome bearing reduces friction and mechanical noise while extending fan longevity. PWM control and Zero RPM support enable low-noise operation by stopping the fan at low loads.

Suitable for

• Case airflow improvement in desktop PC builds
• Radiator cooling in liquid-cooled systems
• Replacement or upgrade for 120 mm fan mounts

How to use

Install the RS120 ARGB into a compatible 120 mm fan mount in your case or on a radiator using the supplied screws. Connect the 4-pin PWM cable to a motherboard fan header to enable speed control and Zero RPM operation. Connect the +5V ARGB cable to a 5V ARGB header on the motherboard to control lighting through compatible software. Configure fan curves and lighting profiles in your motherboard’s ARGB and fan control utilities.

Recommendations

For best cooling and noise balance, position the RS120 ARGB to create a consistent airflow path through your case or across radiator fins, and use PWM fan curves to limit maximum speed when full performance is not required.
