HANNORD PWM Fan Splitter 1-to-4 Braided 10 in 2 Pack

SKU CH-23KE-64ZBV

Connects four case fans to one motherboard header using a 10-inch braided cable with one 4-pin and three 3-pin male connectors

  • ColorBlack

Style 2 Pack

  • Connect four fans to one motherboard header

  • One 4-pin plus three 3-pin connectors simplify mixed-fan builds
  • Single tachometer line gives accurate speed feedback
  • 10-inch length fits compact and full-size cases

2-Pack Braided PWM Splitter

Each pack contains two 10-inch cables that connect four case fans to a single motherboard header. One 4-pin female plug splits into one 4-pin male and three 3-pin male connectors, all wrapped in black braided sleeving. Only the 4-pin branch carries the yellow RPM signal wire back to the board. The cables suit 3-pin and 4-pin PWM fans alike.

Builders adding multiple fans to one header

Ideal for owners who want to run up to four fans from a single CPU or chassis fan header without buying a powered hub. The design reports speed from only one fan, so all four spin at the same PWM duty cycle. Not for users who need independent speed curves per fan or full 4-pin monitoring on every connector. Also unsuitable if the header cannot supply enough current for the combined fan load.

Single RPM wire on one branch

The splitter provides just one tachometer return path, meaning the motherboard reads speed from a single fan while the other three follow the same PWM signal blindly. This limits per-fan monitoring and failsafe detection. Check that your board header can deliver the total amperage required by all attached fans before installing.

Questions about this item

What does the 1-to-4 split mean for fan control on a single motherboard header?

Only one of the four connectors carries the RPM signal wire, so the motherboard reads speed from that fan while all four fans receive the same PWM duty cycle and spin together.

How does the 4-pin PWM header on the board limit what the splitter can do?

The board header supplies one PWM signal and one tachometer input; the splitter passes that single signal to four fans but can only report speed from the one 4-pin branch.

How much clearance does the 10 inch cable need between the motherboard header and the fan mounts?

Each cable is approximately 10 inches long, so allow roughly that much routing space from the header to the furthest fan.
