EN-Labs 6.1 in 1-to-2 PWM Fan Splitter Cable 22AWG

SKU CH-BV8R-HFGDY

Connects one motherboard header to two PWM fans with only one tachometer signal reported

  • TypeFan splitter cable
  • Length6 inches
  • Cable Length6.1 in.
  • Connector Number3
  • Splits one motherboard header to two PWM fans
  • 1 in cable keeps routing tidy inside the case

  • Only the CPU-fan connector passes RPM signal to motherboard
  • Secondary fan follows PWM control without reporting speed

6.1 in PWM Fan Splitter Cable

This 22AWG splitter connects a single motherboard 4-pin header to two PWM fans. Only the fan attached to the full 4-pin connector reports its RPM signal back to the board, preventing conflicting tachometer readings. The second fan receives the same PWM control signal but omits the sense wire. The black net jacket sleeves the tinned copper UL1007 wiring for tidy cable management.

Sustained 12V Operation

Both fan connectors deliver continuous 12V or 5V power drawn from the motherboard header, so neither fan loses voltage under prolonged load. PWM duty-cycle commands travel to both fans simultaneously, keeping speeds synchronised during extended gaming or rendering sessions. The single RPM feed remains stable because the second connector physically lacks a tach pin, eliminating signal bounce that can confuse fan-curve software over time.

Motherboard Header Current Limit

Total current for both fans is capped by the motherboard header rating, typically 1 A, so combined fan draw must stay within that bound. The 6.1 in length reaches adjacent CPU and chassis headers without strain but cannot span full-tower distances. Builders needing more than two fans or headers spaced farther apart should use a powered hub instead.

Questions about this item

Will the 22AWG cable handle 12 V continuous load without overheating?

The 22AWG tinned-copper conductors are rated for 12 V DC operation and the UL1007 insulation is designed for sustained current in typical PWM fan circuits.

Does my motherboard need a 4-pin PWM header to use this splitter?

Yes, the splitter plugs into a single TX4 4-pin motherboard header and provides two TX4 4-pin outputs for the fans.

If I connect a 3-pin fan to the 3-wire connector will it still follow the PWM curve?

The 3-wire connector carries the PWM control signal so a 3-pin fan will vary its speed with the motherboard curve, but only the fan on the full 4-pin connector reports RPM.
