## Summary description

The Jonsbo SL-120B is a 12 cm fan designed for efficient cooling with a speed range of 600 to 1500 RPM. It operates quietly at 22 dB on low speed and 32 dB on high speed, providing a maximum airflow of 59.48 CFM. The fan features a hydraulic bearing for durability and is available in black and white colors.

## Long description

The Jonsbo SL-120B is a 120 mm case fan engineered for steady airflow and low-noise operation. With a rotational speed range from 600 to 1500 RPM, this fan balances cooling performance and acoustic comfort. The SL-120B delivers up to 59.48 CFM of airflow and uses a hydraulic bearing designed to extend service life while maintaining consistent operation. Available in black and white finishes, the fan fits standard 120 mm mounting points and is suited for system cooling where quiet, reliable ventilation is required.
Advantages
The fan provides a wide speed range that allows adjustment between silent and higher-performance modes, offering measured noise levels of approximately 22 dB at low speed and 32 dB at high speed. Its hydraulic bearing reduces friction and wear compared with sleeve bearings, supporting longer operational lifetime and stable rotation. A compact 120 mm form factor ensures compatibility with most PC cases, radiators and heatsinks that accept 120 mm fans. The combination of up to 59.48 CFM airflow and moderate static characteristics enables efficient heat removal for typical desktop workloads.
Suitable for
 Case ventilation for desktop PCs
 Supplementary cooling for CPU air coolers and GPU shrouds
 Intake or exhaust fan positions in mid-tower and full-tower cases
 Replacement for existing 120 mm fans to reduce noise or improve airflow
Key specifications

 Speed range: 600–1500 RPM
 Airflow: up to 59.48 CFM
 Noise level: approximately 22–32 dB depending on speed

How to use
Install the fan into a compatible 120 mm mounting location using the provided screws or appropriate mounting hardware. Connect the fan power connector to a motherboard fan header or compatible fan controller to allow speed regulation within the 600–1500 RPM range. For best performance, orient the fan so airflow direction aligns with your case ventilation strategy—typically front and bottom fans as intakes and top and rear fans as exhausts. Verify secure mounting to minimize vibration and check that cables are routed away from the blades.
Usage recommendations
For a balance of low noise and effective cooling, use the fan at moderate speeds during everyday tasks and increase speed under sustained load. Combine with dust filters on intake positions and perform periodic cleaning to maintain airflow. If precise speed control or integrated lighting is required, pair the fan with a dedicated fan controller or a motherboard header that supports PWM or voltage-based speed management.
