SKU CH-XR04-EM5V6

120 mm PWM chassis fan provides quiet cooling for ID-COOLING systems

  • 120 mm fan fits standard case mounts
  • PWM control adjusts speed to thermal load
  • Silent operation keeps system noise low
  • ID-COOLING compatibility simplifies installation

120mm PWM case fan for quiet builds

This 120mm fan uses PWM control to adjust speed automatically, keeping noise low while moving air through a chassis. It suits builders who want a straightforward cooler for everyday desktop use.

Practical limits of 120mm PWM cooling

A single 120mm fan cannot match the airflow of larger or multi-fan arrays, so heavily overclocked CPUs or multi-GPU setups may need additional cooling. Buyers who want higher static pressure for dense radiators will find this fan insufficient.

Questions about this item

Should I pick the 120 mm PWM version or a different size?

The fan is a 120 mm PWM model, so choose it if your case has a 120 mm mount and your motherboard provides a 4-pin PWM header for speed control.

What does the 120 mm PWM rating mean once the fan is installed?

It means the fan fits a standard 120 mm mounting pattern and the motherboard can vary its speed automatically through the 4-pin PWM signal, keeping noise low at idle and raising airflow under load.
