CPU Cooler Jonsbo CR-1000 MAX V2 — air cooler with PWM fan, black

Jonsbo CR-1000 MAX V2 is an air CPU cooler for desktop PCs with a PWM-controlled fan that adjusts speed according to processor temperature. The cooler is finished in black and uses direct-contact heat dissipation to transfer heat from the CPU to the cooling fins. It is designed for mainstream desktop and gaming systems where compact, reliable air cooling is required and provides a simple mounting system for common CPU sockets.

Advantages

The PWM fan enables automatic speed regulation to balance cooling performance and acoustic level depending on thermal load. Direct-contact heat dissipation improves thermal transfer from the CPU heat spreader to the cooler, supporting more consistent temperatures under varying workloads. The compact air cooler design offers straightforward installation and compatibility with typical desktop PC layouts.

Suitable for

• General desktop computers that need improved CPU thermal performance
• Mid-range gaming systems where a compact air cooler is preferred
• Builds that require a black-colored cooler for visual consistency
• Systems where automatic fan speed control (PWM) is desired

When it may not be suitable

This cooler is intended for typical desktop and gaming configurations; it may not provide the same thermal capacity as larger tower coolers or multi-fan high-performance air solutions in extreme overclocking scenarios. Systems that require liquid cooling, very low noise at high heat loads, or the absolute lowest CPU temperatures for heavy overclocks might need a different cooling approach.

Key specifications

• Cooling type: air cooler with PWM-controlled fan
• Finish/color: black
• Heat dissipation method: direct-contact heat transfer to fins
• Target use: desktop PCs, gaming and general-purpose systems

How to use

Install the cooler on a compatible CPU socket following the included mounting steps: apply a thin, even layer of thermal paste to the CPU heat spreader, align the cooler base with the CPU, and secure the mounting brackets according to the motherboard socket type. Connect the fan cable to the motherboard CPU fan header to enable PWM control so the motherboard can adjust fan speed based on temperature. Ensure there is adequate case airflow and that the cooler clears nearby RAM modules and other components before powering on the system.

What to consider before purchase

• Verify mechanical compatibility with your motherboard socket and available clearance inside the case
• Confirm that the black finish fits your build’s aesthetics
• Check that PWM fan control is supported by your motherboard fan header

Recommendations

For consistent results, pair the cooler with a case that provides good intake and exhaust airflow. Monitor CPU temperatures after first boot to confirm the fan profile responds to load as expected and reseat the cooler if temperatures are higher than anticipated.
