## Long description

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.
Usage 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.
