140mm System & Case Fans

PC components emit a lot of waste heat, and whether you opt for an air-cooler, all-in-one hydrocooler or custom watercooling loop your case will need fans to keep everything cool.

This category contains a huge variety of 140mm fans, these used by a huge variety of cases, air-coolers, all-in-one hydrocoolers and watercooling radiators.

Keep an eye out for the airflow, normally measured in CFM (Cubic Feet per Minute) with a higher number indicating more airflow. It's also worth looking at the sound level, normally measured in dBA, with a lower number indicating less noise. Some fans are also optimised for use on radiators, and will be marketed as having a higher static pressure than standard case fans.
