Eight black 4-pin fan speed reducer cables with male and female connectors

Vszerda

Vszerda 8pcs Temperature Control Fan Speed Reducer 4 Pin Male Female

SKU CH-BGGB-5MQW2

Eight temperature-controlled cables automatically slow 4-pin PC fans when components run cooler

  • Temperature-based speed control reduces fan noise
  • 4-pin male-to-female connectors fit standard PWM headers
  • Eight cables included for multi-fan setups
  • Lowers RPM without BIOS changes

Eight Temperature-Controlled Fan Reducers

This pack provides eight 4-pin male-to-female adapters that automatically lower fan speed when system temperatures drop. Each cable inserts between a PWM header and a fan, allowing the motherboard to regulate RPM based on thermal load without manual intervention. The connectors suit standard PC cooling fans and require no external power or software configuration.

Automatic Speed Reduction for Quieter Operation

The temperature-sensitive circuitry reduces airflow only when cooling demand falls, cutting acoustic noise during light workloads while preserving full speed under heavy loads. Builders who need constant maximum airflow regardless of temperature, or systems lacking 4-pin PWM headers, will not benefit from this automatic behaviour.

Highlights

Questions about this item

Will the temperature-sensing wire on these 4-pin fan reducers degrade and need replacing?

The temperature-control line is a passive cable assembly with no moving parts or active electronics, so there is no component that wears out under normal operation.

What limits sustained use when these reducers are left in a hot chassis?

The plastic connector housings and wire insulation set the practical ceiling; prolonged exposure above their temperature rating will make the materials brittle before any electrical failure occurs.
