Noctua NA-YC1 Fan Y-Cable Splitter (Floor Stock)

Floor Stock: Workshop Remainders

These come off our own bench. Some were swapped out during in-house upgrades, some are surplus from a build run, and some carry light handling marks from the workshop. Every one is tested and fully functional. Sold as-is at a workshop price.

The Noctua NA-YC1 is a sleeved Y-cable that splits one 4-pin PWM fan header into two, so you can run a second fan off a board that only gives you one fan socket. An easy way to add airflow to a Bitaxe without giving up the header you already use.

One branch is a 4-pin socket and the other is 3-pin. Both fans take their speed signal from the same header and ramp together, but only the fan on the 4-pin branch reports its RPM back to the board, because a single header can only read one tacho signal.

Fits:

• Noctua NF-A4x20 40mm fans
• Noctua NF-A6x15 and NF-A6x25 60mm fans
• Any standard 3-pin or 4-pin PWM fan header

Worth checking that your board's fan header can supply enough current for two fans before you split it.
