Corsair RS120 120mm Black Case Fan 3-Pack

Corsair RS120 | 120mm Black PWM Case Fan Kit

The Corsair RS120 Computer case Fan 12 cm Black 3 pc(s) kit offers a direct-to-motherboard solution for UK PC builders seeking efficient cooling. This triple-pack is designed for users upgrading their case airflow or radiator setup without the clutter of hub cables. The key USP is the integrated daisy-chain capability, allowing you to connect multiple fans through a single 4-pin PWM header.

Product Specifications

Seamless Daisy-Chain Connectivity

You can skip the fan hub entirely with this kit. The RS120 fans feature a sequential daisy-chain design. This allows you to connect all three fans to a single 4-pin PWM header on your motherboard. It reduces cable clutter significantly. This simplifies the build process and improves the visual cleanliness of your case.

Optimised Airflow and Static Pressure

These fans are engineered to handle both airflow and static pressure effectively. This makes them suitable for mounting as case fans or on radiators. The blade shape uses an optimised angle and airfoil profile. This design maximises air movement efficiency. The housing supports the largest possible blade radius for a 120mm fan.

Corsair Airguide Technology

The fans feature stator vanes that angle the exhaust airflow cone. This focusing technology improves the coverage of radiator fins. Better coverage aids in heat dissipation. It ensures that cooling performance is targeted and efficient across your components.

Low-Noise Magnetic Dome Bearing

Every source of noise has been addressed in the RS120 design. The magnetic dome bearing minimises friction and mechanical noise. This provides a balance between high airflow and a low acoustic footprint. The reduced friction also contributes to greater longevity for the fan.

Zero RPM Mode Support

PWM control allows for precise speed adjustments. You can set the fans to spin only as fast as necessary for your system’s temperature. This results in lower overall noise output. Additionally, Zero RPM mode support means the fans can stop completely at low loads. This eliminates fan noise entirely during light tasks.

Key points to check

• Confirm your PC case has sufficient 120mm fan mounting points.
• Verify your motherboard has available 4-pin PWM headers for connection.
• Ensure the fan thickness (25mm) fits your specific case clearance.
• Check if the fan cable length is adequate for your intended layout.

Common questions

Q: Do these fans come with a controller or hub?

A: No, they connect directly to your motherboard via a 4-pin PWM header using a daisy-chain method.

Q: Are these fans suitable for radiator use?

A: Yes, they are engineered for both case airflow and static pressure needed for radiators.

Q: What is the maximum noise level?

A: The noise level reaches up to 36 dBA at the maximum rotational speed of 2100 RPM.

Q: What is the fan dimension excluding the frame?

A: The fan dimensions are 120 x 120 x 25 mm, which is the standard size for 120mm fans.
