Overview

The Corsair RS120 ARGB (CO-9050180-WW) is a 120mm PWM case fan engineered for builders who want strong thermal performance and vivid lighting without a tangle of cables. Its standout feature is daisy-chain connectivity: each fan links to the next, so an entire row of RS120 fans connects to your motherboard through a single 4-pin PWM header and a single +5V ARGB header. This dramatically simplifies wiring in multi-fan configurations and frees up motherboard headers for other components.

On the performance side, the RS120 delivers up to 72.8 CFM of airflow at speeds reaching 2,100 RPM, backed by 2.8mm-H2O of static pressure for effective radiator and heatsink cooling. Corsair's AirGuide technology uses anti-vortex vanes to straighten and focus airflow toward hot components rather than letting it scatter. A magnetic dome bearing keeps operation smooth and extends the fan's service life. Each fan houses eight individually addressable RGB LEDs that are managed through your motherboard's native ARGB software, offering broad compatibility across major motherboard brands without the need for proprietary controllers or additional software.

Key Features

Streamlined Fan Connections: Daisy-chain multiple fans together and control them all through just one 4-pin PWM connector and one +5V ARGB connector.

Lighting Made Easy: Eight LEDs per fan shine bright with customisable lighting through your motherboard’s built-in ARGB control (requires compatible motherboard).

Precise PWM Speeds: Set your fan speeds up to 2,100 RPM while providing up to 72.8 CFM airflow to your system.

CORSAIR AirGuide Technology: Anti-vortex vanes direct airflow at your hottest components for concentrated cooling, pushing air in the direction you need when mounted to a radiator or heatsink.

High Static Pressure: RS fans work well as radiator fans with a static pressure of 2.8mm-H2O to push through obstructions.

Pros & Cons

👍 Pros

Daisy-chain design significantly reduces cable clutter and simplifies multi-fan installations
AirGuide anti-vortex vanes concentrate airflow onto components instead of dispersing it
High 2.8mm-H2O static pressure makes it effective as a radiator-mounted fan
Eight ARGB LEDs per fan produce vivid, customizable lighting via standard motherboard headers
PWM control allows precise speed adjustment from idle to 2,100 RPM

👎 Cons

36 dB at maximum RPM may be noticeable in quiet environments
Requires a motherboard with +5V ARGB headers for lighting control — no standalone controller included
Single-fan package means multi-fan builds require purchasing several units individually
Not compatible with Corsair iCUE, limiting integration with other Corsair RGB peripherals

Frequently Asked Questions

How does the daisy-chain feature work on the RS120?

Each RS120 fan has connectors that let you link multiple fans together in sequence, so an entire chain of fans runs off just one 4-pin PWM header and one +5V ARGB header on your motherboard.

Does the Corsair RS120 require iCUE software to control the RGB lighting?

No, the RS120 uses standard +5V ARGB headers and is controlled through your motherboard's built-in ARGB software. It does not require Corsair iCUE, though it does require a compatible motherboard with ARGB support.

Is this fan suitable for use on a radiator?

Yes, with 2.8mm-H2O static pressure and AirGuide anti-vortex vanes, the RS120 is designed to push air effectively through radiators and heatsink obstructions.

What is the maximum noise level of this fan?

At full speed of 2,100 RPM, the RS120 produces up to 36 dB of noise.

What type of bearing does the RS120 use?

The RS120 uses a magnetic dome bearing, which is designed for long-term reliability and quiet operation.
