Each FC120 fan features a single cable that transmits both power and RGB data signals that can be daisy-chained in a series of fans to reduce cable clutter. The fan interconnect system removes the need for a hub and makes it easy to synchronize control of PWM and RGB for up to 4 fans Designed with precision, the FC120 features enhanced static pressure and concentrated airflow for outstanding cooling performance Built with high-quality polybutylene terephthalate (PBT) for increased durability and wear resistance
