Koellichaam Jonsbo CR-1200E 9,2 cm 2000 RPM zwart

The Jonsbo CR-1200E is a compact black heatsink and radiator designed for CPU cooling in desktop systems. It integrates a 92 mm fan capable of up to 2000 RPM and a low-profile fin block with overall dimensions of 93 mm width, 63 mm depth and 128 mm height, providing a balance between airflow and compatibility with mid- and small-form-factor cases. The unit is finished in black and weighs approximately 0.35 kg, making it suitable for builds where space and weight constraints matter.

Advantages

The CR-1200E delivers targeted airflow from a 92 mm fan at up to 2000 RPM, supporting effective heat dissipation from the fin array while maintaining a small footprint. Its compact dimensions and moderate weight enable installation in a wide range of computer cases without interfering with RAM modules or other nearby components. The black finish reduces visible reflections and blends with common motherboard and case color schemes.

Suitable for

• Cooling consumer desktop processors in compact or mid-tower PC cases
• Systems using supported sockets such as AM4, AM5, LGA 1700, LGA 1200 and LGA 1150
• Builds where low-profile cooling and unobtrusive aesthetics are required

How to use

Prepare the motherboard and CPU surface by removing old thermal paste and applying a new, thin, even layer according to the thermal paste manufacturer’s instructions. Position the heatsink over the CPU aligning the mounting hardware with the motherboard’s socket mounting points for the supported socket type. Secure the cooler using the supplied mounting brackets and screws, ensuring even pressure across the CPU surface. Connect the 3- or 4-pin fan connector to the appropriate CPU fan header on the motherboard for automatic speed control. After installation, verify clearance with RAM modules and adjacent components and run the system to confirm proper fan operation and stable CPU temperatures.

Recommendations

For reliable performance, use compatible thermal paste and follow motherboard manual instructions for mounting on each supported socket. Configure fan curves in BIOS or system software to balance noise and cooling based on workload. Periodically clean the fan and fin surfaces from dust to maintain airflow and cooling efficiency.
