SKU CH-HAD4-RGF5Q

Reduces fan speed by 30% via a 3-pin motherboard connection to lower noise

  • Reduces fan noise by lowering speed 30%
  • Simple 3-pin connection plugs straight into motherboard header
  • Cuts airflow turbulence for quieter operation
  • No software or BIOS changes required

3-pin fan speed reducer for quieter builds

This adapter connects to a standard motherboard 3-pin fan header and lowers the fan speed by 30 percent, cutting audible noise without removing airflow entirely. It suits builders who want a simple, passive way to quiet a CPU or case fan in a home or office PC. No software configuration or external power is required.

Passive inline adapter that frees a PWM header

The device sits inline between the header and the fan, so the motherboard retains speed reporting while the reduced voltage handles the slowdown. It leaves PWM headers free for temperature-controlled fans and works with any 3-pin fan that draws within the header’s current limit. Builders needing variable thermal curves or support for high-current fans should use active fan controllers instead.

Domande su questo articolo

How much does the 3-pin speed reducer lower fan RPM?

The cable cuts fan speed by 30 percent, which directly reduces RPM and airflow proportionally.

Does the reducer cable itself generate heat or noise during continuous operation?

The passive inline resistor adds no audible noise and negligible heat; all sound and thermal changes come from the slower fan.
