Which should you buy, Corsair ML140 PRO RGB or Lian Li UNI FAN SL140?
The Corsair ML140 PRO RGB suits quiet RGB case airflow and builders who dislike loud RGB fans, though it is not built for thick radiator duty (insufficient static pressure) and Maximum-CFM case airflow. The Lian Li UNI FAN SL140 is the one to take for mixed 120/140mm UNI FAN SL builds and quiet open-air intake and exhaust, though it is the wrong buy for radiator duty needing higher static pressure and builds without a case window. Our rating of the Corsair ML140 PRO RGB (8/10): A quiet, glowing 140mm fan best suited to case airflow rather than radiator duty.
