Kotelotuuletinsarja Jonsbo ZA-420W — 3×140 mm PWM ARGB, valkoinen

Jonsbo ZA-420W is a set of three 140 mm PWM-controlled case fans with integrated ARGB lighting in a white finish. Designed for chassis and cooling setups that require balanced airflow and visual customization, this kit fits standard 140 mm mounts for front, top, rear or radiator applications. The fans combine variable speed control via PWM with addressable RGB illumination to adapt performance and appearance to different system needs.

Advantages

The PWM control allows automatic fan-speed adjustment according to motherboard or fan controller signals, providing efficient cooling when required and low noise during idle. ARGB lighting offers individually addressable effects for synchronized color schemes with compatible controllers. The white frame and blades improve aesthetic integration into light-themed builds while reducing visible dust contrast. Compact three-fan packaging simplifies multi-fan installations and ensures matched airflow and acoustic characteristics across all installed fans.

Suitable for

• Case air circulation in mid-tower and full-tower desktop PCs
• Mounting on 140 mm-compatible radiators for liquid-cooling loops
• Front or top intake/exhaust configurations to improve system temperatures
• Systems where synchronized ARGB lighting and a white visual theme are desired

Key specifications

• Fan size: 140 mm
• Control type: PWM speed control compatible with standard 4-pin headers
• Lighting: Addressable RGB (ARGB) with per-LED control via compatible controller or motherboard header
• Frame color: White
• Set quantity: Three fans per package
• Mounting: Standard 140 mm screw pattern

How to use

Install each fan into the case or radiator using the 140 mm mounting holes and appropriate screws. Connect the 4-pin PWM power connector to a motherboard fan header or PWM-capable fan controller to enable automatic speed regulation. Attach the ARGB cable to an addressable RGB header or controller that supports the fan's lighting protocol to configure colors and effects. Ensure airflow direction matches the intended intake or exhaust orientation and route cables to avoid interfering with other components or obstructing airflow.

Recommendations

For balanced performance and quieter operation, configure PWM curves in the motherboard BIOS or fan software to ramp fan speed based on CPU or system temperature. When installing multiple fans, maintain consistent orientation for intake/exhaust to create a predictable airflow path. Use a compatible ARGB controller or motherboard software to synchronize lighting across all three fans and other addressable components.
