## Long description

Jonsbo HF3-120B is a 120mm PWM case fan in black designed for chassis cooling. The fan supports pulse-width modulation (PWM) for automatic speed adjustment when connected to a compatible motherboard or fan controller. Its standard 120mm frame fits most desktop cases and offers balanced airflow and acoustic performance for general ventilation, drive bays, or CPU radiator support in compact builds.
Advantages
The HF3-120B provides controlled cooling through PWM regulation, allowing the system to reduce fan speed under light loads and increase airflow when temperatures rise. Its 120mm size delivers efficient air movement while maintaining moderate noise levels. The fan’s black finish and conventional mounting hole pattern ensure compatibility with a wide range of cases and cooling setups without requiring special adapters.
Suitable for
Case ventilation in desktop PCs
Supplementary airflow for drive bays and components
Mounting on 120mm CPU radiators or small liquid-cooling loops
System upgrades to improve thermal management
Key specifications
Frame size: 120 mm
Control type: PWM speed control
Color: black
Standard 4-pin fan connector for motherboard fan headers
Mounting: four-hole 120 mm pattern
How to use
Install the fan into a compatible 120 mm mounting location in the case, aligning it according to the airflow direction marked on the frame. Secure the fan with screws through the four mounting holes. Connect the 4-pin PWM cable to a motherboard fan header or a PWM-capable fan controller to enable automatic speed regulation. Configure fan control in the system BIOS or with motherboard software to set desired temperature thresholds and fan curves.
Usage recommendations
Place intake fans at the front or bottom of the case and exhaust fans at the rear or top to create a consistent airflow path. Ensure the PWM header supports 4-pin control for full automated speed regulation. Keep fan blades and vents free of dust for optimal performance and periodically check mounting screws to prevent vibration noise.
