CT140 Reverse ARGB Sync PC Cooling Fans are Thermaltake’s new generation of PWM fans designed to fit all PC usage scenarios. The CT Series Fans have a fan speed of 1800 RPM and are made with specially tuned fan blades that can push the air further. The new Cable-Integrated Daisy-Chain Design provides more flexibility in cable management. With the reversed fan blades, the RGB lighting is fully visible from different airflow directions, and its 9 addressable LEDs can be controlled through motherboard sync software.
