Data Center Cooling Fans

Cooling can account for up to 30–40% of a data center's energy bill. Choosing the right fan is one of the most effective ways to cut that cost.

Where Fans Are Used in a Data Center

  • Server and storage racks – internal chassis fans push air across hot components.
  • Row and facility cooling – air handling units and CRAC/CRAH units move conditioned air.
  • Telecom and networking cabinets – compact EC axial fans control heat in tight spaces.

AC, DC or EC for Data Centers?

TypeTypical UseKey Benefit
EC FanFacility AHU, cooling units, high-density racksUp to 50% energy savings, variable speed
DC FanServer internal cooling (24V/48V)Low voltage, precise control
AC FanSimple fixed-speed facility ventilationLow cost, rugged

For most modern data centers, EC fans are the preferred choice: they scale speed with load, stay quiet at low demand and dramatically reduce power draw.

Key Specs to Look For

  • Airflow – enough m³/h or CFM to handle the heat load at your target temperature rise.
  • Static pressure – enough Pa to overcome chassis, filter and duct resistance.
  • Speed control – 0–10V or PWM to tune airflow and save energy.
  • Reliability – ball bearings (e.g. NMB) and long service life for 24/7 operation.
  • Certifications – CE, ETL and, in Europe, ErP 2026 compliance.

Frequently Asked Questions

Why are EC fans better for data centers?

EC fans cut energy use by matching speed to actual demand, run quieter at partial load, and have integrated electronics for simple control. Over a data center's life, this can save significant power and money.

Do ANENG fans come with speed control?

Yes. ANENG DC and EC fans support 0–10V/PWM speed control, and axial sizes range from 120mm to 910mm for both rack and facility cooling applications.

Can ANENG design a custom cooling fan for my rack?

Yes. Share your rack's airflow, pressure, voltage and space constraints and our engineers will recommend or customize the right fan for your thermal requirements.
