Where noise is an issue, larger, slower-turning fans are quieter than smaller, faster fans that can move the same airflow.

[22] Axial fans may rotate at speeds of up to around 38,000 rpm for smaller sizes. [23]
These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated..
