• Twelve super bright Rainbow LED lights for striking and clear illumination. • 120 mm fans, the most common size for computer cases and radiators. • Provide optimal cooling performance and quiet operation, ideal for maintaining the internal temperature of the system. • The PWM function allows the motherboard to adjust the fan speed according to cooling demand, which helps reduce noise levels. • Hydraulic bearing that reduces friction and extends the fan's lifespan. • Mounting system with anti-vibration rubber pads on all four corners to reduce noise generated by vibrations. • Bidirectional installation: can either expel hot air or bring fresh air into the computer case. • Includes a triple pack of case fans for computers.
