The right server fan must move air through a restrictive path, respond to changing load, report its health, and keep doing so for thousands of operating hours.

EC fans and DC fans both play an important role in modern thermal management. Although their names are sometimes used loosely, they are not simply interchangeable labels. The right choice depends on your available power source, system size, control requirements, energy target, operating environment, and total cost of ownership.

A 120mm PWM fan is a widely used thermal-management component in servers, industrial cabinets, power supplies, EV chargers, storage systems, and other electronics.
