Overview

The Corsair RS120 ARGB 120mm PWM Fan Triple Pack delivers a combination of efficient cooling and vibrant lighting designed for easy integration into any ATX build. Each fan features Corsair's AirGuide technology, which incorporates anti-vortex vanes into the fan frame to straighten and focus airflow. This directed airflow design is particularly effective when the fans are mounted on a radiator or CPU tower heatsink, pushing concentrated air exactly where cooling is needed most. With speeds up to 2,100 RPM, airflow of 72.8 CFM, and a static pressure rating of 2.8mm-H2O, these fans are capable of handling both case ventilation and liquid cooling duties.

One of the standout features of the RS120 is its daisy-chain connectivity. Rather than running separate cables to individual motherboard headers for each fan, you simply link them together—one fan to the next—using pass-through PWM and ARGB connectors. This means all three fans in the pack can operate from a single 4-pin PWM fan header and a single +5V ARGB header, dramatically reducing cable clutter. Each fan houses eight individually addressable RGB LEDs that are controlled through your motherboard's native ARGB software, so there's no need for additional proprietary controllers or hubs. For builders looking for strong cooling performance, clean aesthetics, and simplified installation, the RS120 ARGB triple pack covers all three at a competitive price point.

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 reduces cable clutter by requiring only one PWM and one ARGB header for all three fans
AirGuide anti-vortex vanes focus airflow directly onto hot components for more effective cooling
High static pressure of 2.8mm-H2O makes them effective radiator fans
PWM speed control up to 2,100 RPM allows a wide range of noise and performance tuning
Eight ARGB LEDs per fan provide vibrant, customizable lighting without proprietary controllers

👎 Cons

36 dB noise at maximum RPM can be noticeable in quiet environments
Requires a motherboard with a +5V ARGB header for lighting control — no standalone controller included
Daisy-chaining means all connected fans run at the same speed, limiting individual fan control
No vibration-dampening rubber mounting pads included on the frame
120mm size only, with no 140mm variant available in this product line

Frequently Asked Questions

How does the daisy-chain connection work on the RS120 fans?

Each fan has pass-through connectors for both the 4-pin PWM power cable and the +5V ARGB lighting cable. You connect one fan to the next in a chain, so the entire set requires only one PWM header and one ARGB header on your motherboard.

What is AirGuide technology and how does it improve cooling?

AirGuide technology uses anti-vortex vanes built into the fan frame to straighten and direct airflow. This concentrates the air stream onto your hottest components rather than dispersing it, which is especially effective when the fans are mounted on a radiator or heatsink.

How loud are these fans at maximum speed?

At full speed of 2,100 RPM, the RS120 fans produce up to 36 dB of noise. Using PWM control to lower the RPM will reduce noise levels significantly during lighter workloads.

Do I need Corsair iCUE software to control the RGB lighting?

No. These fans use standard +5V ARGB, so they can be controlled through your motherboard's built-in ARGB software. However, the motherboard must have a compatible 3-pin +5V ARGB header.

Can these fans be used on a radiator?

Yes. With a static pressure rating of 2.8mm-H2O, the RS120 fans are designed to push air effectively through radiator fins and heatsink obstructions, making them well suited for liquid cooling setups.
