Silent Wings Pro 4 120mm PWM White fan

The be quiet! BL118 is a 120mm PWM case fan designed for builders who prioritise low noise and high static pressure. Its fluid-dynamic bearing and 6-pole motor deliver smooth operation across the speed range. The white, non-LED frame suits clean, light-themed builds.

Upgrade from standard case fans

The jump is worthwhile when your current fans cannot push enough air through a dense radiator or heatsink without becoming loud. A three-position speed switch lets you cap the maximum at medium, high or ultra-high RPM without software. Mounting hardware covers both case and radiator installations.

Handles 80 to 85 CFM at up to 3000 RPM

This airflow and pressure headroom covers most single-radiator liquid loops and high-end air coolers. The 25mm thickness fits standard fan mounts. It runs out of steam in dual-radiator stacks or heavily restricted chassis where even higher static pressure is required.

商品問答

Does the 120 mm frame with 25 mm thickness fit standard case mounts and radiators?

Yes, the 120 x 120 x 25 mm dimensions match standard case fan and radiator mounting holes.

How do I use the speed switch to change the maximum PWM limit?

Move the physical switch on the fan frame to select medium, high or ultra-high speed up to 3000 RPM before powering on.

When should I consider replacing the fluid-dynamic bearing?

The bearing is rated for long life; replace the fan if noise rises above 36.9 dBA or airflow drops below 80 CFM.
