Fan Jonsbo SL-120WR 12 cm 600-1500 RPM 22-32 dB

The Jonsbo SL-120WR is a 120 mm case fan designed for general-purpose PC cooling. It delivers an airflow of approximately 59.48 CFM across a speed range of 600–1500 RPM and operates with low acoustic output between 22 and 32 dB. The fan uses a hydraulic bearing for extended service life and smoother operation, and its white finish integrates with light-themed builds or provides a neutral aesthetic in any chassis.

Advantages

The fan combines moderate maximum airflow with a broad low-to-mid speed range, enabling effective heat removal while keeping noise levels low. Hydraulic bearing technology reduces friction and wear compared with basic sleeve bearings, improving reliability over prolonged use. The compact 120 mm form factor fits standard mounting points in most consumer PC cases, and the white housing offers compatibility with white or minimalist builds.

Suitable for

• Case exhaust or intake in desktop PCs
• Supplementary cooling for GPU or VRM areas
• Replacement for worn or noisy 120 mm fans
• Systems where low noise is a priority

Key specifications

• Fan size: 120 mm
• Speed range: 600–1500 RPM
• Airflow: 59.48 CFM (approx.)
• Noise level: 22–32 dB
• Bearing type: hydraulic bearing

How to use

Install the fan into a compatible 120 mm mounting location in your case using the supplied screws or standard mounting hardware. Connect the fan to an available motherboard header or fan controller using the appropriate power connector; ensure the header supports the fan's voltage and control method. Orient the fan so that airflow direction matches your intended intake or exhaust configuration. After installation, monitor system temperatures and fan speed to confirm correct operation.

Recommendations

For optimal performance and low noise, use the fan at PWM-controlled speeds when possible, maintain clear airflow paths in the case, and clean dust from the fan blades and housing periodically. Avoid obstructing the intake or exhaust areas and ensure the fan mounting is secure to minimize vibration.
