Corsair RS120-R ARGB 120mm PWM Reverse Fans - Triple Pack / Reverse Rotor Keeps Intake Lighting Visible / 8 ARGB LEDs Per Fan / 420-2100 RPM / 65.82 CFM / Magnetic Dome Bearing / Daisy-Chainable PWM and 5V ARGB / CO-9050196-WW

The CORSAIR RS120-R ARGB triple pack supplies three 120mm PWM fans built with reverse rotors, so the lighting stays visible when they are mounted as intake. Each fan carries eight addressable RGB LEDs, spins up to 2,100 RPM, runs on a magnetic dome bearing and daisy-chains to the next fan in the row.

On a normal fan mounted as intake you look at the back of the motor hub and the frame struts. The reverse rotor turns that around so the blade face points outward into the case, which means the lighting and the blades are what shows through the side panel instead of the mounting hardware.

Each fan holds eight individually addressable RGB LEDs driven from a standard +5V ARGB header, so the lighting syncs with ASUS Aura Sync, MSI Mystic Light, GIGABYTE RGB Fusion and ASRock Polychrome. No CORSAIR controller or lighting hub is needed to run them from the motherboard.

The fans chain directly to one another, so three of them run from a single 4-pin PWM connector and a single +5V ARGB connector on the motherboard. That removes the fan hub and the bundle of cables it normally brings, which keeps the area behind the motherboard tray far easier to route.

PWM control varies the speed up to 2,100 RPM according to system load rather than running flat out, moving up to 65.82 CFM of air at a rated 34.6 dBA. Because the speed is governed by the motherboard curve, the fans stay quiet at idle and only ramp when the temperature actually calls for it.

At low load the fans can stop turning altogether rather than idling at a low speed, which takes their noise contribution to nothing during light desktop work or while browsing. They start again as soon as the curve calls for airflow, so the cooling is there when the load arrives.

The magnetic dome bearing reduces the friction between the moving parts, which cuts the mechanical noise a fan makes independently of the air it moves and extends how long it runs before the bearing becomes audible. It is the reason the fan holds a low acoustic figure while still pushing meaningful airflow.

The blade angle of attack, airfoil profile and edge curvature are tuned to serve both open case airflow and the static pressure a radiator needs, and the housing carries the largest blade radius that fits a 120mm frame. That lets the same fan work as a case intake or on a radiator.

The pack contains three RS120-R ARGB fans in the standard 120mm by 25mm size along with the mounting screws. Three fans is the count a front intake or a 360mm radiator takes, so the pack populates a full row without needing a second purchase to finish the job.

This is the three-fan retail pack rather than a single fan, supplied in one box with the daisy-chain cabling already fitted to each unit. Additional RS-R ARGB fans can be chained onto the same run if the case has room for more than three positions in a line.
