Ventilátor Jonsbo SL-120BR 12 cm čierny biely 600-1500 ot/min 22-32 dB

The Jonsbo SL-120BR is a 120 mm case fan designed to provide steady airflow and quiet operation for desktop computers. With a rotational speed range from 600 to 1500 RPM, this black-and-white fan delivers up to 59.48 CFM of airflow while maintaining acoustic levels between 22 and 32 dB. The fan uses a hydraulic bearing to improve service life and reduce operational noise, and its 12 cm form factor makes it compatible with a wide range of ATX, micro-ATX and mini-ITX enclosures where standard 120 mm mounts are available.

Advantages

The fan combines a broad speed range and modest noise levels to balance cooling performance and sound output for everyday and light to moderate computing tasks. The hydraulic bearing enhances durability compared with sleeve bearings and helps maintain stable operation over longer periods. Available in black and white finishes, the model can match common case interiors and contribute to a clean aesthetic while fitting standard 120 mm mounting points.

Suitable for

• Case cooling for desktop PCs (ATX, micro-ATX, mini-ITX)
• Replacing worn or noisy 120 mm fans
• Improving airflow for GPU or HDD bays
• Silent or low-noise system builds for office or home

How to use

Install the fan into any standard 120 mm mounting location in the computer case, aligning the airflow direction arrows if present. Secure the fan with the provided screws or compatible mounting hardware and connect the fan cable to the motherboard fan header or a suitable fan controller. When connected to a 3-pin header, fan speed is controlled by voltage variation; when used with a controller, set the desired RPM profile to balance cooling and noise. Periodically inspect the fan for dust accumulation and clean with compressed air to maintain performance.

Recommendations

For quieter operation, mount the fan as an intake or exhaust in positions with fewer obstructions and set the fan to lower RPM during low-load periods. Maintain regular dust cleaning and ensure adequate case ventilation to extend the hydraulic bearing life and sustain airflow performance.
