PWM Control Case Fans

PWM control enables precise command over your fan speeds, so you can set the exact RPM you want for each fan. Customize your PWM fan speeds to get higher performance or lower noise, exactly when you need it.

What to look for in a PWM control case fan

Look closely at the specs as you’re eyeing a fan in this category.

  • Size: Does your case need a 120mm or 140mm case fan?
  • Bearing type: Check for magnetic dome or standard physical or hydraulic bearings.
  • Static pressure and RPMs: How fast and how hard your fan blows.
  • Control protocol: With PWM fans, check to see what kind of software or programming capability there is.
  • Design: Look for RGB LEDs, LCD screens for readouts, and different colorways.

What is a PWM control fan in a PC?

The abbreviation “PWM” stands for “Pulse Width Modulation”. While most traditional PC case fans simply turn on and off as they’re needed, a PWM fan allows you to control the amount of power and the gradual ramp-up of the fan’s operation. This functionality, when paired with precise control software like CORSAIR’s iCUE protocol, can let you dial in the perfect fan performance for your system. Not only does this help your system run more quietly and take some of the wear and tear off of your fan units, it also ensures that the hottest components in your system have just the right level of cooling for their needs.
