CPU cooler Jonsbo CR-1000 V3 PRO PWM ARGB, black

Jonsbo CR-1000 V3 PRO PWM ARGB in black is a tower-style air cooler designed for standard desktop systems. It combines a single tower heatsink with a PWM-controlled fan and addressable RGB lighting to deliver active cooling for CPUs in gaming PCs, workstations and home computers. The cooler uses a vertical fin stack and a single fan to move heat away from the processor, while ARGB illumination integrates with compatible motherboard headers.

Advantages

The cooler provides PWM fan control for automatic speed adjustment according to CPU temperature, supporting quieter operation at low loads and increased airflow under heavy load. The tower heatsink offers a compact footprint that fits many mid-tower and full-tower cases. Addressable RGB lighting allows synchronization with motherboard software that supports ARGB headers. The black finish gives a neutral appearance that suits a wide range of system builds.

Suitable for

• Gaming desktops requiring improved CPU cooling
• Workstations with moderate to high processor loads
• Home PCs where quiet thermal management and ARGB lighting are desired

Key specifications

• Cooling type: air cooler, single-tower design
• Fan control: PWM (pulse-width modulation) for automatic speed regulation
• Lighting: addressable RGB (ARGB) compatible with standard ARGB headers
• Finish: black
• Compatibility: designed for standard desktop CPU sockets (check motherboard header for ARGB support)

How to use

Install the cooler according to the motherboard and case instructions, mounting the base onto the CPU with the supplied bracket and thermal interface material. Connect the fan to a CPU fan or chassis fan header that supports PWM control for automatic speed adjustment, and connect the ARGB cable to an addressable RGB header on the motherboard or compatible controller to enable lighting control. Ensure there is sufficient clearance around the RAM and case side panel when positioning the cooler.

Recommendations

Use PWM fan control via the motherboard to balance noise and cooling performance. Verify ARGB header pinout compatibility before connecting lighting to avoid damage. Periodically clean dust from the fins and fan to maintain thermal efficiency and monitor fan operation within the system BIOS or software.
