Dual 3-Pin Fan Splitter Set

The NA-SYC2 includes two black Y-cables that each let a single motherboard header drive two 3-pin fans. Builders expanding case airflow on headers already occupied can add a second fan without hunting for spare connectors. The set suits systems where fan headers are scarce but 3-pin cooling devices are plentiful.

Continuous Load Behaviour

Each header typically supplies 9.6 or 12 watts, so the combined draw of both fans must stay within that limit. The cable passes the RPM signal from one fan to the board for monitoring while the second fan runs without reporting speed. Exceeding the header rating risks instability or shutdown under sustained operation.

Three-Pin Connector Constraint

These splitters only accept 3-pin fans; 4-pin PWM fans will not fit the connectors. Buyers needing PWM control or 4-pin compatibility must choose a different cable type. The 115 mm length and black sleeving keep routing tidy in tight chassis.

Questions about this item

Will the 3-pin Y-cables add audible noise or extra heat when two fans run all day on one header?

The cables are passive splitters with no active components, so they add no audible noise or measurable heat beyond the fans themselves.

What must already be present on the motherboard for the 3-pin connectors to work?

A standard 3-pin fan header is required; the male plug connects there and the two female plugs accept 3-pin fans.

How does the 115 mm cable length behave when paired with older 3-pin fans that lack PWM control?

The splitter passes the RPM signal from one fan to the board, so speed monitoring works while both fans run at the same voltage.
