120mm fans have enjoyed a massive surge in popularity in recent times, with many case manufacturers now including 120mm fan cutouts as standard. The big advantage of a 120mm fan is that because its blades are larger than any of the other common fan sizes, the fan does not have to spin as quickly in order to produce a given amount of airflow. This means less noise and longer life! With our large range of 120mm fans, there is sure to be a fan to suit any budget and airflow requirement.
