CPU-jäähdytin Jonsbo CA40 musta ARGB, 120 mm PWM-tuuletin, 225 W TDP, musta

Jonsbo CA40 BLACK ARGB is a tower air CPU cooler designed for desktop processors. It features a compact heatsink combined with a 120 mm PWM fan and addressable RGB lighting. The cooler is engineered to provide effective heat dissipation for mainstream and higher-load systems while fitting in cases that support a 120 mm fan form factor. Rated for a 225W thermal design power (TDP), this unit balances cooling performance with a smaller footprint and ARGB integration for system aesthetics.

Advantages

The combination of a dense fin stack and a 120 mm PWM fan enables stable airflow and adjustable fan speed to match processor load and noise preferences. Addressable RGB lighting allows synchronized illumination with compatible motherboards and controllers. The compact tower design reduces compatibility issues in mid-tower and some smaller cases and simplifies installation compared with larger multi-fan coolers.

Suitable for

• Mainstream desktop processors requiring up to 225W cooling capacity
• PC builds with a 120 mm fan mounting and limited cooler clearance
• Systems where PWM fan control and reduced noise at low loads are desired
• Builds that include ARGB lighting or require synchronized illumination

Key specifications

• Cooling type: tower air cooler
• Fan size: 120 mm
• Fan control: PWM (pulse-width modulation)
• TDP rating: 225 W
• Lighting: addressable RGB (ARGB) support
• Finish: black

How to use

Mount the cooler on a compatible CPU socket following the included mounting hardware and the motherboard manufacturer’s guidance. Apply a thin, even layer of thermal paste to the CPU heatspreader before seating the cooler. Connect the fan’s PWM cable to the CPU_FAN or SYS_FAN header for automatic speed adjustment and attach the ARGB cable to a compatible ARGB header or controller for lighting control. Ensure the cooler is firmly secured and that airflow direction aligns with your case ventilation scheme.

Recommendations

For optimal performance, pair the cooler with a case that provides clear intake and exhaust airflow paths and enable PWM control in BIOS or fan-control software. Check cooler clearance against memory modules and case components before installation. Regularly clean dust from fins and the fan to maintain thermal efficiency.
