EN-Labs PWMSPL36 PWM Fan 4-Pin to 3×4-Pin Splitter Cable 10

SKU CH-WGY4-69ZY6

A 10-inch PWM splitter cable connects three 4-pin fans to one motherboard header for synchronised speed control

  • Connector count4
  • Connector genderFemale to Male
  • Product typeCable Splitters
  • Product colorBlack
  • Overall length6 in - 10 in
  • DetailsType :PWM fan power cable Length: 10 in Conductor:26AWG Copp
  • Connect three PWM fans to one motherboard header using a 10 inch cable
  • 26 AWG copper conductors deliver 12 V and 5 V power to each fan
  • Master 4-pin connector sends RPM signal for synchronised speed control
  • Two slave 3-pin headers omit RPM pin so all fans follow the same PWM curve
  • Supports both 3-pin and 4-pin fans with unified speed management

PWM fan splitter for triple-fan headers

The EN-Labs PWMSPL36 cable splits a single motherboard 4-pin PWM header into three fan connections. It lets builders run three PWM fans from one header while keeping speed control centralised. The 10-inch length suits typical case routing without excess slack.

Thermals noise and power delivery

The splitter passes 12 V and 5 V lines through 26 AWG copper conductors to each attached fan. Only the master 4-pin connector returns an RPM signal to the motherboard; the other two headers omit that pin so all fans follow the same PWM curve. Total current draw stays within the header's rated limit.

Master-slave connector behaviour

The master 4-pin plug enables software such as AI Suite, Xpert Fan or EasyTune to regulate every connected fan identically. Fans attached to the 3-pin headers run at full speed when PWM control is absent, so speed synchronisation depends on using the master connector. Sleeved black wiring keeps the installation tidy.

Questions about this item

How do I connect the 4-pin female end to my motherboard header and avoid mixing up the master and slave plugs?

Plug the single 4-pin female connector into the motherboard 4-pin header, then attach the fan you want monitored to the 4-pin male lead; the other two 3-pin male leads run at the same PWM speed without RPM feedback.

Will I need to replace the cable if I upgrade to higher-wattage fans later?

The 26 AWG copper conductors are rated for 12 V and 5 V fans; as long as the combined draw of the three fans stays within the motherboard header limit, no cable replacement is required.

What is the first limit I hit when running three fans continuously at full speed?

The motherboard header’s current rating becomes the bottleneck before the 10-inch, 26 AWG cable reaches any thermal limit.
