Six-pack ARGB 120 mm fans

The DARKROCK F120 6-pack supplies six 120 mm case fans with infinite-mirror ARGB lighting on both blades and frame. Each fan uses a hydro-dynamic bearing and eight rubber pads to reduce vibration. PWM control lets the motherboard vary speed between 800 and 1600 RPM. The pack is aimed at builders who want coordinated lighting and airflow for a standard ATX chassis.

Sustained-load airflow behaviour

At full PWM duty the fans move up to 46.7 CFM while spinning at 1600 RPM. The nine-blade design maintains steady pressure across radiators or dense heatsink fins, so airflow does not collapse during long rendering or gaming sessions. Speed scales linearly with temperature curves set in BIOS, avoiding sudden rpm spikes when load changes.

Thermals acoustics and power draw

Maximum noise is rated at 27.7 dBA at 1600 RPM, dropping proportionally at lower speeds. The hydro bearing and rubber mounts keep vibration-induced resonance low even after extended operation. Each unit draws power through a standard 3-pin connector, so total system draw rises only modestly when all six fans run at peak speed.

Questions about this item

How loud are the 120 mm fans at full 1600 RPM when they run all day?

Maximum noise is 27.7 dBA at 1600 RPM, with a hydro-dynamic bearing and eight rubber anti-vibration pads to keep long-term operation quiet.

What motherboard headers are needed to control the 6-pack's ARGB lighting and PWM speeds?

Each fan needs a 3-pin 5 V ARGB header for the 24 LEDs and a 4-pin PWM header for 800–1600 RPM speed control; the pack includes no separate controller.

Will these 120 mm fans fit the mounting holes on my older 120 mm radiator or air cooler?

Yes — standard 120 mm square frame with 25 mm thickness matches legacy 120 mm radiator and cooler mounts.
