## Long description

The Scythe Kaze Flex 140 Square RGB PWM is a 140 mm computer cooling fan designed to provide balanced airflow and low noise for case and component cooling. Operating at 12 V, the fan's rotational speed ranges from 300 to 1200 RPM and it delivers static air pressure between 0.08 mmH2O and 1.25 mmH2O, enabling efficient air movement through radiators, filters and tight case layouts. The product is available in white and black colour options and is suitable for users who need a quiet, PWM-controlled fan with integrated RGB lighting and solid build quality.
Advantages
The Kaze Flex 140 Square RGB PWM combines a wide RPM range with controlled air pressure to suit different cooling needs while keeping acoustic levels low. PWM control allows automatic speed adjustment according to system temperature, and the fan's square frame and 140 mm diameter support compatibility with common mounting locations and many radiators. The RGB integration provides customizable lighting without compromising the fan's core cooling function.
Suitable for
Case ventilation and chassis airflow enhancement
Cooling of air or water-cooling radiators compatible with 140 mm fans
Replacement or upgrade of existing 140 mm fans to reduce noise
Systems where PWM speed control and RGB lighting are required

How to use
Install the fan in a compatible 140 mm mounting location in your case or on a radiator following the case manufacturer’s mounting instructions. Connect the PWM power cable to a motherboard fan header or PWM fan controller to enable automatic speed regulation. Connect the RGB cable or header according to your case or controller specifications to control lighting. Ensure the fan orientation matches the intended airflow direction for intake or exhaust. Secure the fan using appropriate screws or vibration-damping mounts to minimize mechanical noise.
Usage recommendations
Use PWM control to balance cooling performance and noise, and place the fan where airflow is unobstructed for optimal static pressure performance. Regularly clean dust filters and fan blades to maintain airflow and cooling efficiency. When pairing multiple fans, configure them to work together as intake or exhaust to create a consistent airflow path through the case.
