LIAN LI UNI FAN SL140 140 mm RGB PWM Case Fan 2-Pack with Controller, White

The LIAN LI UNI FAN SL140 140 mm RGB PWM Case Fan 2-Pack with Controller, White is a two-fan set for computer case intake or exhaust cooling. Each 140 mm fan operates at up to 1,500 RPM. Maximum airflow is rated at 70.5 CFM, providing substantial air movement through a compatible case. Static pressure reaches 1.67 mmH₂O, which helps the fans move air past typical internal restrictions. The stated noise level at maximum speed is 30 dB.

The white fan frames are 25 mm thick, matching the standard depth used for case fans of this diameter. Integrated multi-colour LED lighting adds configurable illumination to a coordinated PC build. A UNI HUB controller is supplied for centralised fan and lighting management. PWM support allows speed adjustment through the controller or a compatible motherboard according to cooling demand. This set is designed for case airflow and does not support processor sockets or CPU mounting brackets.

• Fluid Dynamic Bearing: bearing type used in both supplied fans
