Arrefecedor de CPU Jonsbo CB40 preto ARGB Single-Tower 225W TDP, ventoinha PWM de 120mm

Jonsbo CB40 black ARGB Single-Tower is a CPU cooler designed for desktop systems that require effective heat dissipation and customizable lighting. The cooler pairs a single-tower aluminum heatsink with a 120mm PWM fan and ARGB illumination to provide temperature control for mainstream processors with a rated cooling capacity up to 225W TDP. Its compact single-tower layout and variable-speed fan allow it to balance cooling performance and acoustic levels in typical ATX and micro-ATX builds.

Advantages

The CB40 combines a dense fin stack and direct-contact heatpipes with a 120mm PWM fan to deliver stable thermal transfer and adjustable airflow. ARGB lighting offers customizable visual integration with other compatible components and motherboard software. The fan’s PWM control enables automatic speed adjustment based on CPU temperature, reducing noise during low-load operation while providing higher airflow under heavy load.

Suitable for

• Mainstream desktop PCs for everyday productivity and light content creation
• Gaming builds where mid-range thermal performance and ARGB lighting are desired
• Compact towers and systems with limited clearance that accept single-tower coolers
• Users who prefer PWM fan control and motherboard-synchronized ARGB illumination

Key specifications

• Cooling design: Single-tower heatsink with integrated heatpipes
• Fan size and type: 120mm PWM fan with variable speed control
• Rated cooling capacity: 225W TDP
• Lighting: Addressable RGB (ARGB) compatible with motherboard control
• Material highlights: aluminum fins and heatpipes for thermal conduction
• Compatibility: Designed for standard desktop CPU sockets with typical mounting brackets

How to use

Install the CB40 on a compatible CPU socket following the motherboard and cooler mounting instructions: apply a thin, even layer of thermal paste to the CPU heatspreader, align the cooler base, and secure the mounting hardware to the motherboard bracket. Connect the 4-pin PWM fan header to the CPU_FAN or system fan header for automatic speed control, and plug the ARGB cable into a compatible 5V ARGB header or controller to enable lighting. Ensure there is adequate clearance for RAM modules and side panels before finalizing installation.

Recommendations

For optimal results, configure fan curves in BIOS or motherboard software to balance noise and cooling, maintain case airflow with intake and exhaust fans, and periodically clean dust from the heatsink and fan blades to preserve thermal performance and ARGB functionality.
