CPU cooler Jonsbo CR-1400 E BLACK with 140mm fan, air cooler for processors

Jonsbo CR-1400 E BLACK is an air CPU cooler equipped with a 140mm fan designed to provide directional airflow for removing heat from desktop processors. The compact tower-style cooler is intended for systems that need standard, efficient cooling while maintaining low noise levels. It fits common motherboard sockets—confirm compatibility with your CPU socket before purchase—and is suited for everyday computing where steady thermal performance and reliability are required.

Advantages

The cooler combines a large-diameter 140mm fan with a compact heatsink profile to balance cooling performance and space efficiency. Its airflow design focuses on dissipating heat away from the CPU and toward case exhaust, helping to maintain stable operating temperatures. The unit is engineered for quiet operation in typical desktop workloads and for easy installation in systems with limited clearance around the CPU area.

Suitable for

• Home and office desktop PCs requiring reliable, low-noise CPU cooling
• Compact mid-tower or small-form-factor cases with support for a 140mm top/front fan layout
• Systems used for web browsing, office applications, media playback and light productivity
• Builds where a balance of cooling efficiency and reduced acoustic level is desired

Key specifications

• Cooling type: air cooler with 140mm fan
• Fan size: 140 mm
• Form factor: compact tower heatsink
• Intended use: desktop CPU thermal management
• Noise profile: designed for low-noise operation in typical workloads
• Compatibility: fits common consumer motherboard sockets (verify specific socket support before installation)

How to use

Prepare the motherboard and CPU by following the motherboard manufacturer’s instructions for cooler installation and CPU cooler retention mechanisms. Apply a thin, even layer of thermal paste to the CPU heatspreader if thermal paste is not pre-applied on the cooler. Position the Jonsbo CR-1400 E BLACK so the fan directs airflow toward the chosen case exhaust path, align mounting hardware with the socket retention brackets and secure the cooler evenly to avoid uneven pressure. Connect the fan cable to the CPU fan header on the motherboard and configure fan control settings in BIOS/UEFI or through your operating system utilities for desired fan behavior.

Recommendations

Ensure adequate case airflow by maintaining clear intake and exhaust paths and by keeping dust filters clean. Confirm clearance for memory modules and tall RAM heatsinks when installing, and monitor CPU temperatures after installation to verify expected cooling performance.
