Corsair CO-9050189-WW RS120 120mm PWM Daisy-Chain Fans (3-Pack)

The Corsair RS120 120mm PWM fan 3-pack is built for PC builders who want straightforward, high-performance cooling without the complexity of RGB controllers or proprietary hubs. The headline feature is daisy-chain connectivity: each fan includes both an input and output 4-pin PWM connector, so you can link all three fans together and control them from a single motherboard header. This dramatically simplifies cable routing and is especially useful in builds where motherboard fan headers are limited or hard to reach.

On the performance side, each fan spins up to 2,100 RPM and pushes 72.8 CFM of airflow with 4.15mm-H₂O of static pressure — enough to drive air effectively through radiators and tightly packed heatsink arrays. Corsair's AirGuide technology incorporates anti-vortex vanes into the fan frame, which straighten turbulent airflow and direct it more precisely onto heat-generating components. The magnetic dome bearing at the center of each fan minimizes friction and mechanical noise, contributing to quieter operation and an extended service life. At 4.8 watts per fan and a peak noise level of 36 dB, the RS120 strikes a practical balance between cooling capacity and acoustic comfort for a wide range of PC configurations.
