Fan Corsair RS120 ARGB 12 cm White 420-2100 RPM 3 pcs

The Corsair RS120 ARGB is a 120 mm case and radiator fan sold as a 3-piece pack in white. It operates within a 420–2100 RPM range and delivers strong airflow and a maximum static pressure of 4.15 mmH2O. The fan is designed for direct-to-motherboard connection using one 4-pin PWM connector for speed control and one +5V ARGB connector for lighting, enabling synchronized RGB control via major motherboard software such as ASUS Aura Sync, MSI Mystic Light Sync, ASRock RGB and Gigabyte RGB Fusion.

Advantages

Direct-to-motherboard connection removes the need for additional fan hubs and excess cables, simplifying installation and control. The aerodynamic blade shape, expanded blade radius supported by the housing, and Corsair AirGuide stator vanes improve airflow efficiency and focus exhaust through radiator fins for better heat dissipation. A magnetic dome bearing reduces friction and mechanical noise while extending fan lifespan. PWM speed control and Zero RPM support allow for quieter operation by stopping the fan at low loads when cooling demand is minimal.

Suitable for

• Case cooling in desktop PCs
• Radiator fans for liquid CPU/GPU cooling
• Systems requiring ARGB lighting synchronized with motherboard software
• Builds that prefer direct motherboard fan and lighting control without hubs

How to use

Install the fans in your case or on your radiator using the appropriate mounting screws. Connect the 4-pin PWM cable to a motherboard fan header to enable automatic speed control, and connect the +5V ARGB cable to a compatible ARGB header for lighting control. Use your motherboard’s ARGB software suite to customize lighting effects and configure fan curves in BIOS or via motherboard software to set PWM profiles and enable Zero RPM behavior at low temperatures or low load.

Recommendations

For optimal cooling and quiet operation, position RS120 ARGB fans to create a consistent airflow path (intake at front/bottom, exhaust at rear/top) and configure PWM curves so the fans remain stopped in Zero RPM mode during idle if temperatures allow. Ensure your motherboard has a +5V ARGB header and a 4-pin PWM fan header per fan or use headers that support multiple fans if available.
