140mm PWM ARGB Case Fan Jonsbo ZA-140B — 140mm, PWM control, ARGB, black

Jonsbo ZA-140B is a 140mm PWM-controlled case fan with addressable RGB illumination in a black finish. Designed for general PC cooling, the fan delivers adjustable airflow through PWM control while offering customizable lighting via ARGB headers. The ZA-140B fits chassis and radiator mounts that accept 140mm fans and combines cooling performance with addressable RGB effects for a visually coordinated system.

Advantages

The ZA-140B uses PWM control to vary fan speed according to motherboard or controller signals, enabling a balance between cooling performance and acoustic level. Its ARGB lighting supports addressable LED control for per-LED effects and color customization, allowing integration with compatible ARGB ecosystems. The 140mm form factor provides larger blade area than 120mm alternatives, which can move more air at similar rotational speeds while maintaining lower noise in many operating ranges. The black finish ensures a neutral appearance that matches a wide range of builds.

Key specifications

• Fan size: 140 mm
• Control interface: PWM speed control
• Lighting: Addressable RGB (ARGB) illumination
• Color/finish: Black

How to use

Install the Jonsbo ZA-140B in any standard 140mm fan position in your case or on a compatible radiator, aligning the mounting holes and securing with the supplied screws or compatible fasteners. Connect the PWM power connector to a motherboard fan header that supports PWM control to allow dynamic speed regulation. Connect the ARGB cable to an addressable RGB header or ARGB controller to enable lighting customization; follow the motherboard or controller documentation for pin orientation and software setup. After powering the system, adjust fan curves and lighting profiles through BIOS or supported software to meet desired cooling and visual preferences.
