Air cooler Jonsbo CR-1000 EVO 12 cm Black 600-1500 RPM

The Jonsbo CR-1000 EVO 12 cm Black air cooler is a compact CPU cooling solution designed for mainstream desktop systems. It combines a 120 mm fan with a hydraulic bearing and a rotational speed range of 600–1500 RPM to deliver balanced airflow and acoustic performance. With a rated thermal design power (TDP) of 220 W and a lightweight profile, this cooler is intended to maintain processor temperatures within recommended limits while fitting standard PC cases.

Advantages

The 120 mm fan provides steady airflow with minimum and maximum air pressure values of 0.26 mmH2O and 1.81 mmH2O respectively, enabling effective heat transfer from the heatsink. Hydraulic bearing technology reduces operational noise and increases durability compared with basic sleeve bearings. The cooler’s compact weight of 0.554 kg and black finish make it suitable for a variety of builds where space and visual integration are considerations.

Suitable for

• Mainstream desktop CPUs requiring up to 220 W TDP cooling
• Small to mid-tower PC cases where a 120 mm cooler profile is preferred
• Users seeking a balance of cooling performance and low noise

How to use

Install the cooler according to the motherboard and case manufacturer instructions: apply a thin, even layer of thermal paste to the CPU heatspreader, align the cooler mounting bracket with the supported socket, and secure the unit firmly but without excessive torque. Connect the fan cable to the CPU_FAN or designated fan header on the motherboard to enable speed control. Verify clearance for RAM modules and surrounding components before finalizing installation.

Recommendations

For stable thermal performance, enable PWM or fan curve control in the BIOS or with monitoring software to match fan speed to CPU load. Periodically check and clean the heatsink fins and fan to prevent dust buildup, and ensure case airflow is adequate to maximize the cooler’s effectiveness.
