Ruth's sister 10pcs 4Pin 1 to 2 Extension Cable 20cm internal power cable

10-Pack 4-Pin Fan Splitters

This set provides ten 4-pin 1-to-2 extension cables that turn a single motherboard header into two fan connections. Each splitter is 20 cm long and uses pure copper conductors inside a sleeved jacket. The pack is aimed at builders who need to run more chassis or CPU fans than the board’s native headers allow.

Extends And Doubles 4-Pin Headers

Each cable plugs into a standard 4-pin PWM header and branches into two female 4-pin connectors, letting you add a second fan without occupying another motherboard port. The 20 cm length helps reach fans mounted at the top or rear of the case while keeping routing tidy. No extra power adapters or controllers are required; the splitters draw directly from the header.

Handles Two Fans Per Header

One splitter comfortably runs a pair of 4-pin PWM fans from a single header, giving you up to twenty fan connections across the ten cables. The limit is the current rating of the motherboard header itself, so very high-speed or high-draw fans may exceed what the single header can supply. Builders needing more than two fans per header will need a powered hub instead.
