Sada ventilátorov Jonsbo ZL-120B PWM ARGB 120mm, 3 ks

Set of three 120 mm Jonsbo ZL-120B PWM ARGB case fans designed for PC cooling. Each fan combines PWM speed control and addressable RGB lighting to balance airflow, noise and visual customization in desktop builds. The pack is suitable for chassis ventilation, radiator or heatsink cooling and for improving overall thermal performance in gaming and productivity systems.

Advantages

The Jonsbo ZL-120B PWM ARGB fans offer variable-speed operation through PWM control for precise airflow management and reduced acoustic output at low loads. Addressable ARGB LEDs allow per-fan lighting effects compatible with common motherboard sync standards. The compact 120 mm form factor fits most standard fan mounts while delivering effective static pressure for radiators and restrictive front intakes. The included trio provides consistent airflow across multiple mounting positions, simplifying balanced cooling configurations.

Suitable for

• Case ventilation in mid-tower and full-tower desktop PCs
• Radiator or AIO liquid cooler mounting
• Improving airflow for CPU and GPU cooling
• Systems requiring synchronized ARGB lighting effects

Key specifications

• Fan size: 120 mm diameter
• Control: PWM speed control for automatic RPM adjustment
• Lighting: Addressable RGB (ARGB) per fan
• Quantity: 3 fans in the set
• Mounting: Standard 4-screw 120 mm mounting pattern
• Connector types: PWM power/speed connector and ARGB connector (compatible with common motherboard ARGB headers)
• Applications: Case intake/exhaust and radiator use

How to use

Install each fan into the case or radiator using the 4-screw mounting points, ensuring correct airflow direction for intake or exhaust based on your cooling layout. Connect the PWM power/speed cable to a compatible motherboard fan header to enable automatic speed control; if the motherboard lacks PWM headers, use a compatible fan controller. Attach ARGB connectors to an addressable RGB header or controller to enable lighting control and synchronization. After installation, verify fan operation in BIOS or software and adjust PWM curves or lighting profiles as required for temperature and noise preferences.

Recommendations

Position fans to create a consistent airflow path (front/bottom intake, top/rear exhaust) and avoid obstructing airflow with cables. For radiator mounts, orient fans to push or pull depending on your preferred thermal performance and dust management strategy. Periodically inspect and clean the fans and ARGB connectors to maintain performance and reliable lighting operation.
