Three-fan pack with aluminium frame

This Lian Li BR DIGITAL-3R S kit supplies three 120 mm case fans built around a sandblasted aluminium frame. Each fan runs on a fluid-dynamic bearing and offers PWM control between 900 and 1800 RPM. Independent addressable RGB lighting uses twelve LEDs per fan for per-LED colour control.

Builders who want coordinated RGB and a metal frame

The pack suits builders who want matched airflow and synchronised lighting across three intake or exhaust positions. The 27 mm thickness and 1.46 m-H2O static pressure figure mean the fans are less suited to very tight radiator stacks or slim cases where a thinner profile is required.

27 mm frame thickness

At 27 mm thick these fans occupy more depth than many standard models, so the single dimension that decides fit is the 27 mm frame thickness. Check your case, radiator or cooler clearance against that figure before purchasing.

商品問答

What clearance does the 27mm thickness need in my case?

Each fan measures 120mm x 120mm x 27mm, so verify your case allows at least 27mm depth at the mounting points.

How do I connect the 4-pin PWM and the 5V ARGB cables correctly?

Plug the 4-pin connector into a motherboard PWM header for speed control and the 3-pin 5V ARGB header into a matching 5V addressable RGB header; reversing them will prevent lighting control.

When should I expect to replace the fluid dynamic bearings?

The fluid dynamic bearing is rated for long life; plan replacement only if noise rises above the 19.4~29 dBA range or RPM drops below 900~1800 RPM under load.
