Three-pack 140 mm PWM case fans

This three-pack supplies three 140 mm PWM case fans for system builders who want coordinated airflow and addressable RGB lighting in a single purchase. The fans suit standard case mounting points and connect via a 4-pin PWM header. They are not suited for buyers who need a bundled fan controller or fans smaller than 140 mm.

Thermals noise and power draw

Each fan operates between 500 and 1700 RPM, moving 20 to 78 CFM while producing less than 10 dB(A) at low speed and up to 35.5 dB(A) at maximum speed. Aerodynamic stator struts and Trip Wire technology reduce turbulence for smoother airflow. Rifle bearings lower friction compared with standard sleeve bearings.

Bundled accessories and software

The box includes twelve mounting screws for securing all three fans. Each fan carries six individually addressable hub-mounted RGB LEDs compatible with ASUS AURA, Gigabyte Fusion, MSI Mystic Light and ASRock Polychrome. Power and RGB cables support daisy-chaining to reduce cable clutter. No separate lighting controller or software suite is included.

Questions about this item

How do I chain the power and RGB cables between the three 140 mm fans without a separate controller?

Connect the 4-pin PWM and ARGB leads from one fan to the next using the built-in pass-through connectors on each unit; the chain draws power and signal from a single motherboard header.

When will the rifle bearings need replacement under continuous 1700 RPM operation?

Rifle bearings last significantly longer than sleeve types; expect several years at full speed before any noise increase signals wear.

At what airflow does noise hit the 35.5 dB(A) ceiling during sustained loads?

The 35.5 dB(A) maximum occurs at 78 CFM when the fan runs at 1700 RPM; lower speeds stay below 10 dB(A) at 20 CFM.
