Three y-cables for dual PWM fans

The NA-SYC1 chromax.black set contains three y-cables that let two 4-pin PWM fans run from a single motherboard header. Both fans receive the same speed signal so the board controls them together. The 4-pin plugs also accept 3-pin fans, though PWM regulation only works with 4-pin models. Multiple cables can be daisy-chained to drive more than two fans from one header.

Combined current stays within header limits

Each mainboard header typically supplies up to 9.6 or 12 watts, so the total draw of the attached fans must not exceed that figure. Exceeding the limit can cause instability or damage the header. The cables themselves add no active circuitry; they simply split the existing power and signal lines. Builders should verify the combined fan wattage against the board manual before connecting several units.

Black sleeving matches chromax fans

Every cable is wrapped in black sleeving for a clean, uniform look that blends with Noctua chromax.black fans. Copper conductors carry the power and PWM signals without extra bulk. The short 0.015 kilogram assemblies add minimal weight inside the case. Connectors are keyed 4-pin PWM types that fit both 3-pin and 4-pin fan plugs, keeping cable routing tidy in compact builds.

Questions about this item

How much power can the NA-SYC1 chromax.Black y-cables draw continuously from a single motherboard fan header?

Common mainboard fan headers support up to 9.6 or 12W. Check your mainboard manual for the exact limit and ensure the combined power draw of both connected fans stays within that rating.

What fan headers and fan types are required to use the NA-SYC1 chromax.Black y-cables?

You need one free 4-pin PWM fan header on your motherboard and two fans with 4-pin PWM connectors for full speed control. The cables also accept 3-pin fans, but PWM control only works with 4-pin models.

Will the NA-SYC1 chromax.Black y-cables control older 3-pin fans the same way as 4-pin PWM fans?

The 4-pin connectors fit both 3-pin and 4-pin fans, but PWM control is only supported with 4-pin fans. Older 3-pin fans will run at a fixed voltage instead of receiving PWM signals.
