Fan Cryorig Crona S 120 mm Black — 400–1700 RPM, 16.5–29.7 dB, 60.6 CFM, 2.65 mmH₂O

The Cryorig Crona S 120 mm Black is an axial case fan designed for PC cooling and airflow management. It has a 120 mm diameter and a slim 25.4 mm profile, delivering adjustable speed from 400 to 1700 RPM. The fan provides up to 60.6 CFM airflow and a static pressure of 2.65 mmH₂O while producing noise levels between 16.5 dB and 29.7 dB. The single-piece black unit is suitable for use in chassis, on CPU coolers, or with radiators.

Advantages

The Crona S offers a compact slim design that fits standard 120 mm mounts while maintaining efficient airflow and pressure for a range of cooling needs. Its adjustable speed range allows balancing between cooling performance and acoustic level, and the black finish integrates with different build aesthetics. The unit is lightweight and easy to install, and pre-installed acoustic absorbers reduce transferred vibration.

Suitable for

• Case ventilation for mid-tower and compact PC builds
• Supplementary cooling on CPU coolers or heatsinks
• Installation on radiators for liquid-cooling loops where a 120 mm slim fan is required

How to use

Mount the fan using the appropriate 120 mm screw holes to your case, fan bracket, radiator, or heatsink following the orientation that directs airflow where needed (intake or exhaust). Connect the fan to your motherboard or fan controller using the compatible power connector provided by the system or controller. Adjust the fan speed through BIOS, motherboard software, or an external fan controller to match your desired balance of cooling and noise.

Recommendations

For quieter operation, run the fan at lower RPMs within the 400–900 RPM range when system temperatures are moderate. For improved cooling on radiators or dense heatsinks, increase RPM closer to the upper range while monitoring noise. Ensure the fan is mounted with acoustic absorbers contacting the case or bracket surface to minimize vibration transfer. Periodically clean the fan blades to maintain airflow and performance.
