The Akasa AK-CBCA29-15BK PWM fan cable adapter is designed to expand your cooling capabilities. This adapter converts a single 4-Pin PWM fan header on your motherboard into two 4-Pin PWM fan connectors, enabling you to connect and control two PWM fans simultaneously. The 15cm cable length provides sufficient reach for convenient fan placement within your system. By using PWM (Pulse Width Modulation) control, the fan speeds can be automatically adjusted based on temperature, optimizing cooling performance and minimizing noise. Supreme Components International is an authorised distributor of Akasa products, ensuring you receive a high-quality, reliable component. This adapter is ideal for users looking to improve airflow and cooling in their PC build without needing additional fan controllers.
