Model RS120 ARGB White Triple Pack

  • Daisy-chain three fans with one PWM and one ARGB connector
  • Eight ARGB LEDs per fan controlled via motherboard software
  • Up to 2100 RPM and 72.8 CFM airflow for concentrated cooling
  • AirGuide anti-vortex vanes direct air at hottest components
  • Magnetic Dome bearing runs at 10 dBA minimum with zero RPM mode

Triple-pack 120 mm ARGB case fans

This set contains three white 120 mm case fans with addressable RGB lighting and magnetic dome bearings. Each fan spins from 420 to 2100 RPM and moves between 13.3 and 72.8 CFM of air. Daisy-chain wiring lets you control all three units through a single 4-pin PWM header and one 5 V ARGB header. The pack includes twelve mounting screws for installation.

Suits builders who want synchronised lighting

The fans are designed for standard 120 mm case or radiator mounts and deliver up to 4.15 mm-H2O static pressure. Zero RPM mode stops the rotors completely at low loads for silent operation. Builders needing different frame sizes, non-illuminated fans, or higher airflow at lower noise should consider other options.

Daisy-chain 4-pin PWM and 5 V ARGB connectors

A single PWM signal and a single ARGB signal drive the entire triple pack, reducing cable clutter and motherboard header usage. This connection scheme is the deciding factor for systems with limited fan or lighting headers.

Questions about this item

Will the magnetic dome bearings need lubrication or replacement after long-term use?

The magnetic dome bearing is designed to minimise friction without lubrication and has no user-serviceable parts, so no routine maintenance is required.

What limits continuous airflow when the fans run at the top speed of 2100 RPM?

At 2100 RPM the fans deliver 72.8 CFM and 4.15 mm-H2O static pressure; the motor’s PWM ceiling is the first limit reached under sustained load.

How loud are the three fans together when running all day at maximum speed?

Each fan reaches 36 dBA at full speed, so three fans operating together will be audible but remain within the rated noise specification.
