140mm ARGB PWM case fan

The Silverstone Shark Force SF140B-ARGB is a 140mm case fan built for builders who want adjustable cooling and addressable lighting in a single unit. It suits new system builds and upgrades where a 140mm mounting point is available. The fan targets users who value low-noise operation across a wide speed range.

PWM control and modular cabling

A 0 to 2200rpm PWM range lets the motherboard or fan controller match airflow to thermal load automatically. The three-phase, six-pole motor design aims to deliver smoother rotation than conventional four-pole designs. Modular cables reduce clutter by allowing only the necessary connections inside the chassis.

Standard ARGB 4-1 pin lighting

The addressable RGB LED connects via a standard 4-1 pin header, enabling per-LED colour control through compatible motherboard software or a dedicated ARGB controller. No proprietary lighting ecosystem is required. The fluid dynamic bearing supports long-term reliability at varying speeds.

Questions about this item

What is the maximum RPM of the Silverstone SF140B-ARGB fan under sustained load?

The fan reaches a maximum of 2200 RPM via PWM control, which is the upper limit of its speed range.

How loud or hot does the 140mm Shark Force fan get when running all day at high speed?

Its three-phase, six-pole motor and fluid dynamic bearing are designed for smoother, quieter operation and improved energy efficiency compared to common four-pole designs.

Which motherboard header or controller is required for the ARGB lighting on this fan to function?

It uses a standard ARGB 4-1 pin connector, so it needs a compatible 5V addressable RGB header on the motherboard or a separate ARGB controller.
