Air cooler Jonsbo CR-1400 EVO 9.2 cm Black 800-2200 RPM 22.3-33.8 dB

The Jonsbo CR-1400 EVO is a compact air cooler equipped with a 9.2 cm fan that supports speeds from 800 to 2200 RPM. Designed for use in a variety of PC builds, it delivers targeted cooling with an airflow up to 38.2 cfm while maintaining low acoustic output between 22.3 dB and 33.8 dB. The fan uses a hydraulic bearing to increase reliability and reduce wear, making the cooler suitable for prolonged operation in desktop systems.

Advantages

The cooler combines a relatively high maximum fan speed with a low minimum speed to balance cooling performance and quiet operation. With an airflow rating of up to 38.2 cfm and noise levels rated from 22.3 dB to 33.8 dB, it provides efficient heat dissipation for compact and mid-size enclosures without generating excessive noise. The hydraulic bearing enhances longevity and consistent performance over time.

Suitable for

• Small form-factor and mid-tower PC builds that require a compact air cooler
• Everyday desktop systems used for office work, web browsing, and media playback
• Light to moderate gaming and content-creation systems where a balance of cooling and low noise is desired

Key specifications

• Fan diameter: 9.2 cm
• Rotational speed: 800–2200 RPM
• Airflow: up to 38.2 cfm
• Noise level: 22.3–33.8 dB
• Bearing type: hydraulic bearing

How to use

Install the Jonsbo CR-1400 EVO according to the motherboard and case compatibility, ensuring secure mounting and proper orientation for optimal airflow through the chassis. Connect the fan to the appropriate motherboard header or fan controller to enable speed control within the 800–2200 RPM range. Monitor temperatures and adjust fan curves in the system BIOS or software to achieve the preferred balance between cooling performance and noise.

Recommendations

For best results, position the cooler to align with the case airflow path, keep dust filters clean, and configure a fan curve that increases speed under higher CPU load. Periodic inspection and cleaning of the fan and heatsink surfaces will help maintain rated airflow and low noise levels.
