## Summary description

Air CPU cooler Jonsbo CB40 WHITE ARGB with PWM fan control and addressable RGB (ARGB) lighting.

## Long description

Jonsbo CB40 WHITE ARGB is a compact tower air CPU cooler in a white finish, designed for standard desktop systems and small to mid-size ATX/mATX builds. It combines PWM-controlled airflow with addressable RGB lighting to balance cooling performance, acoustic behavior and visual customization. The cooler uses a single tower heatsink and a PWM fan to adapt fan speed automatically according to CPU temperature, while the ARGB system allows synchronized lighting with compatible motherboards or controllers.
Advantages
The compact tower design enables installation in cases with limited clearance while providing effective heat dissipation for mainstream processors. PWM fan control ensures dynamic adjustment of fan RPM to reduce noise at low load and increase airflow when temperatures rise. Addressable RGB lighting provides per-LED control for flexible visual effects and compatibility with common motherboard lighting standards. The white finish offers a neutral aesthetic that integrates with white or light-themed system builds.
Suitable for
 Small to mid-size ATX and mATX desktop builds where cooler height and clearance are limited
 Mainstream office and home PCs requiring balanced cooling and low noise
 Systems where ARGB lighting is desired for synchronized or standalone effects
 Users who prefer a white-themed interior for aesthetic consistency
Key specifications
 Cooling type: air cooler, compact tower configuration
 Fan control: PWM-enabled fan for automatic speed adjustment
 Lighting: addressable RGB (ARGB) per-LED lighting support
 Color / finish: white
 Compatibility: standard desktop CPU sockets on typical ATX/mATX motherboards (check case clearance before installation)
How to use
Install the Jonsbo CB40 WHITE ARGB on a compatible CPU socket following the motherboard and cooler mounting instructions. Connect the PWM fan cable to the CPU\_FAN or designated fan header to enable automatic speed control. Attach the ARGB cable to a compatible 3-pin 5V ARGB header or to an ARGB controller to enable lighting control and synchronization. Ensure adequate case airflow and verify cooler clearance with RAM modules and other components before finalizing installation.
Usage recommendations
For optimal performance, mount the cooler so the fan draws air through the heatsink toward a case exhaust fan. Enable PWM control in the BIOS or motherboard software to allow automatic RPM adjustment. If using ARGB synchronization, use motherboard lighting software or a compatible controller and ensure the header is 5V ARGB. Regularly check and clean the fan and heatsink fins to maintain cooling efficiency.
