120mm skriňový ventilátor Jonsbo ZK-120B Reverse ARGB čierny — 120mm, ARGB, reverzná rotácia

Jonsbo ZK-120B Reverse ARGB Black is a 120mm case fan designed for targeted airflow and synchronized addressable RGB lighting. The fan's reverse-rotation design directs concentrated air streams, making it suitable for use as a chassis intake or exhaust or for mounting on radiators. The black frame and blade set provide a neutral aesthetic that integrates with most builds while the ARGB lighting can be synchronized with compatible controllers for per‑LED effects.

Advantages

The reverse-rotation impeller focuses airflow for improved directional cooling compared with conventional fans. Addressable RGB offers customizable lighting zones and compatibility with common motherboard and controller software. The compact 120mm size fits a wide range of fan mounts and radiators. The black finish minimizes visual distraction and helps the lighting stand out.

Suitable for

• Case airflow optimization in gaming and workstation PCs
• Mounting on CPU or GPU radiators in compact and mid‑tower builds
• Systems requiring synchronized ARGB lighting and visual customization
• Upgrades where focused or directional airflow is needed

Key specifications

• Size: 120 mm fan diameter
• Lighting: addressable RGB (ARGB) with per‑LED control compatibility
• Rotation: reverse-rotation impeller design for focused airflow
• Color: black frame and blades
• Mounting: standard 120 mm screw pattern for chassis and radiators

How to use

Install the fan using the standard 120 mm screw holes to the chassis or radiator bracket, orienting the fan for the desired airflow direction. Connect the power cable to the appropriate motherboard fan header or controller, and plug the ARGB lead into a compatible ARGB header or controller for lighting control. After physical installation, configure fan speed and lighting through the motherboard software or the chosen controller to match system cooling and visual preferences.

Recommendations

Place the fan where focused airflow is required, such as directly over heat-generating components or in tight radiator channels. Ensure the ARGB header type matches your controller to avoid incompatibility. For balanced airflow, combine reverse-rotation fans with standard fans in complementary positions to reduce turbulence and maintain positive or neutral case pressure as preferred.
