Computer Case Fan Kolink Classic HDB 120 mm, 1500 RPM, 52.15 CFM, Black

Kolink Classic HDB 120 mm is a chassis fan for desktop and compact PC cooling. The black 120 mm fan operates up to 1500 RPM and provides a maximum airflow of 52.15 CFM while maintaining a low noise level. It uses a hydraulic bearing designed for extended service life and comes with a 4-pin PWM connector and an optional female PWM pass-through for controlled speed management.

Advantages

The hydraulic bearing reduces internal friction to extend operational life and supports smooth, low-noise rotation. PWM control and a 4-pin connector enable automatic speed adjustment based on system temperature or motherboard fan curves. A compact 120 mm form factor and standard mounting make the fan compatible with most cases and cooling configurations, providing a balance of airflow and acoustic performance.

Suitable for

• Case cooling in desktop PCs and workstations
• Airflow improvement in compact or mid-tower chassis
• Replacement or additional intake and exhaust fans

Key specifications

• Fan diameter: 120 mm
• Maximum speed: 1500 RPM
• Maximum airflow: 52.15 CFM
• Noise level: 21.6 dB(A) at rated speed
• Static pressure: 1.31 mmH2O
• Bearing type: Hydraulic bearing
• Connector: 4-pin PWM male plus female PWM pass-through
• Blade count: 7

How to use

Install the fan into a standard 120 mm mounting location in the case, aligning screw holes and securing with appropriate screws. Connect the 4-pin PWM cable to a motherboard fan header or fan controller to enable automatic speed regulation. If available, use the female PWM pass-through to chain another fan or to route the PWM signal without occupying additional headers. Ensure the fan orientation matches the intended airflow direction for intake or exhaust.

Recommendations

For balanced cooling and low noise, configure motherboard fan curves to allow the fan to run at lower speeds during idle and ramp up as temperatures increase. Regularly check mounting tightness and clean the fan blades to preserve airflow and acoustic performance.
