Three-Pack PWM Fan Splitter Cables
This set provides three Y-type splitter cables that let two 4-pin PWM fans run from a single motherboard header. Both fans receive the same PWM signal so their speeds stay synchronised, while the RPM signal from one fan is reported back to the board for monitoring. The black sleeving and connectors keep cable runs looking clean in chromax-themed builds.
Upgrade From Single-Fan Headers
When a motherboard lacks enough fan headers for every cooler or case fan, these splitters remove the need to leave fans unplugged or running at fixed voltage. Daisy-chaining multiple cables can extend control to more than two fans per header, provided the combined power draw stays within the header's 9.6 or 12W limit. Builders who need independent speed curves for each fan cannot use this passive splitter.
Fits Standard 4-Pin Fan Headers
Each cable splits one female 4-pin connector into two male 4-pin connectors that also accept 3-pin fans, though PWM control only works with 4-pin models. The adapters work with CPU coolers, case fans, mining rig arrays or fan controllers such as the NA-FC1. No extra software or drivers are required — just plug into an existing header and route the sleeved leads to the fans.

Questions about this item
Will the 4-pin connectors on these splitter cables fit both 3-pin and 4-pin fans?
Yes, each female connector accepts both 3-pin and 4-pin fan plugs, but PWM speed control only works with 4-pin PWM fans.
How do I install these cables without exceeding the motherboard header power limit?
Connect the single female end to the header and plug two fans into the male ends, then verify the combined fan draw stays within the 9.6 W or 12 W limit stated in your motherboard manual.
Can I daisy-chain multiple splitter cables to run more than two fans from one header?
Yes, multiple cables can be daisy-chained, but the total power draw of all connected fans must not exceed the 9.6 W or 12 W header rating from your motherboard manual.
