Vszerda
Three-way 4-pin PWM splitter cables connect three fans to one motherboard header for synchronised speed control
This Vszerda splitter cable lets a single motherboard 4-pin header drive three cooling fans at once. One branch carries a 4-pin connector while the other two use 3-pin plugs, so PWM speed control reaches every attached fan. The pack contains three identical cables, ready for builds that need more airflow than a single header can support.
Each cable uses 24 AWG conductors wrapped in a black nylon braid that resists kinking and abrasion during routing. The 10-inch length gives enough slack to reach fans across a typical ATX chassis without leaving excess loops. Dense sleeving keeps the bundle tidy behind the motherboard tray and protects the wires from sharp case edges.
Builders who have exhausted motherboard fan headers can use these splitters to add two extra fans per header without a powered hub. The upgrade makes sense when the board lacks enough PWM headers for front, top and rear intake or exhaust layouts. It does not suit systems that need independent speed curves per fan, because all three fans follow the same PWM signal.
No published specifications for this item yet.
One 4-pin motherboard header splits into three fan connectors: one 4-pin and two 3-pin, letting all three fans run at the same PWM-controlled speed.
Each splitter is 10 inches long with flexible black nylon braid over 24AWG wire, so it routes easily behind motherboard trays and through standard grommets without kinking.
Attach the single 4-pin fan lead to the splitter’s 4-pin branch; the motherboard reads its tach signal and drives all three fans at identical PWM duty cycles.
