Two 140 mm PWM fans with dual RGB loops

This twin pack delivers a pair of 140 mm case fans that use hydraulic bearings and 4-pin PWM control. Each fan contains sixteen independent RGB LEDs arranged in two separate light loops for extensive colour customisation. The included Lighting Node PRO and RGB hub connect to the motherboard and provide centralised lighting management.

Suited for builders who want synchronised RGB

These fans suit enthusiasts who want coordinated lighting across a case and who already own or plan to buy a motherboard with a standard 4-pin fan header. They are not intended for systems that lack PWM headers or for users who prefer single-colour or non-addressable LED strips. Buyers needing higher static pressure for dense radiators should consider alternative designs.

600 to 1300 RPM speed range with 51.5 CFM airflow

The single specification that decides fit is the PWM speed range of 600 to 1300 RPM, which produces 51.5 CFM at a maximum of 25 dBA. This balance of airflow and acoustic output determines whether the fans can meet the cooling demands of a specific chassis configuration.

Questions about this item

What do the two 140 mm fans in this pack include for lighting control?

The pack contains two 140 mm fans, an RGB Lighting Hub and a Lighting Node PRO so you can drive 16 independent RGB LEDs per fan through Corsair iCUE software.

How much airflow and noise should I expect at the top 1300 RPM setting?

At the maximum 1300 RPM the fans move 51.5 CFM each while producing 25 dBA, giving strong airflow with low audible noise.

What does the 4-pin PWM connector let me control on these fans?

The 4-pin PWM header allows the motherboard or Lighting Node PRO to vary speed precisely between 600 and 1300 RPM for quiet or performance modes.
