CPU cooler Jonsbo CR-1000 MAX 120mm, black, model CR-1000 MAX

The Jonsbo CR-1000 MAX is an air CPU cooler with a 120 mm axial fan and an aluminum heatsink, designed for everyday desktop builds. It fits systems using standard tower-style coolers and is intended to lower processor temperatures during typical and sustained workloads. The cooler’s black finish and compact footprint make it compatible with many ATX and micro-ATX cases that support a 120 mm cooling solution, offering a balance between thermal performance and space efficiency.

Advantages

The CR-1000 MAX combines a 120 mm fan with a dense fin stack to improve heat transfer from the CPU to ambient air while maintaining modest acoustic output. Its compact design allows installation in systems with limited clearance around the CPU socket. The black color scheme provides a neutral appearance that integrates with most build themes. The axial fan design delivers consistent airflow across the heatsink for steady cooling under load.

Suitable for

• Standard desktop PCs built on ATX or micro-ATX motherboards
• Office and home workstation systems with moderate CPU loads
• Compact cases that support a single 120 mm cooler
• Users seeking a balance of cooling performance and low noise

Key specifications

• Cooling type: air cooler with 120 mm axial fan
• Fan size: 120 mm
• Color: black
• Heatsink material: aluminum fin stack (with integrated heatpipe base as applicable)
• Compatibility: fits standard ATX and micro-ATX cases supporting 120 mm CPU coolers
• Application: desktop CPU thermal management for everyday and sustained workloads

How to use

Install the cooler on a compatible motherboard following standard CPU cooler mounting procedures for your socket type. Ensure the backplate or mounting brackets are aligned and fastened securely to provide even contact between the heatsink base and the CPU heat spreader. Connect the fan’s power cable to the CPU fan header on the motherboard to enable speed control and monitoring. Verify that there is sufficient clearance for RAM and other nearby components, and route cables to avoid obstructing airflow.

Usage recommendations

Apply a thin, even layer of thermal interface material between the CPU and the heatsink base for optimal heat transfer. Use the motherboard’s BIOS or a fan control utility to set an appropriate fan curve balancing cooling performance and noise levels. Periodically clean dust from the fan and heatsink fins to maintain airflow and thermal efficiency.
