Corsair CO-9050188-WW RS120 120mm PWM Daisy-Chain Fan

The Corsair RS120 is a 120mm PWM case fan built around a straightforward but effective idea: simplify multi-fan installations through daisy-chaining. Each fan features a pass-through connector that links directly to the next RS120, allowing you to run an entire bank of fans from a single motherboard PWM header without splitters, hubs, or extra cable management. For builders who want clean interiors without sacrificing cooling, this design is immediately practical.

Performance is strong across both case airflow and radiator duty. The RS120 pushes up to 72.8 CFM of airflow and delivers 4.15mm-H2O of static pressure, making it capable of forcing air through densely packed radiator fins or heatsink arrays. Corsair's AirGuide technology uses anti-vortex vanes on the fan frame to channel airflow more directly at components, reducing turbulence and improving cooling efficiency. The Magnetic Dome bearing is engineered for reduced friction and lower noise output over time, contributing to a fan that stays quiet at moderate speeds. At full tilt the 36 dB rating is audible, but PWM control means you can dial back to a comfortable noise level for everyday use while still having headroom when thermal loads spike.
