Three-Way PWM Fan Splitter

This pack contains two 4-pin PWM fan splitters that each divide one motherboard header into three fan connections. The cables let a single PWM signal control up to three fans simultaneously, which is useful when the board has fewer headers than the build requires. The 10.6 inch length reaches most fan positions in standard ATX cases. Black PVC braided sleeving protects the wires and resists heat.

Builders with limited fan headers

Suits anyone adding extra case or radiator fans to a motherboard that lacks enough 4-pin connectors. The splitters accept both 4-pin and 3-pin fans, though only the primary 4-pin branch reports speed and responds to PWM control; the two 3-pin branches run at full voltage. Users who need independent speed curves for every fan, or who require more than three fans per header, should consider a powered fan hub instead.

Capacity and headroom

Each splitter handles three fans from one header, so the pair supports up to six fans in total. The motherboard header’s current rating limits how many fans can spin safely; high-amperage fans may exceed that limit. The 11 inch cables provide slack for routing behind motherboard trays or along radiator mounts. Heat-shrink tubing on the connectors guards against oxidation and accidental shorts during installation.

Highlights

  • Connects three fans to one motherboard header
  • PWM speed control on the primary 4-pin connector
  • 6 inch length reaches across the case
  • PVC braided sleeve resists abrasion and heat
  • Heat-shrink tubing protects connectors from oxidation

Questions about this item

What motherboard header do I need to plug this splitter into?

Each splitter connects to a single 4-pin PWM fan header on the motherboard.

Can I use my existing 3-pin case fans with this splitter?

Yes, two of the three branches on each splitter are 3-pin; those fans will run at full, non-adjustable speed.

How can I confirm the PWM fan is actually being speed-controlled after I connect everything?

The fan attached to the 4-pin branch will vary its speed with motherboard PWM signals, while the two 3-pin branches stay at constant full speed.
