Cooling system accessory Noctua NA-SYC2

The Noctua NA-SYC2 is a fan accessory set that contains two fully sleeved NA-YC2 Y-cables for 3-pin fans. Each Y-cable lets you operate two 3-pin fans from a single motherboard or controller fan header while maintaining reliable signal transmission and a tidy appearance thanks to the sleeved cables.

Advantages

The NA-SYC2 provides a simple and compact solution for expanding fan capacity without using additional fan headers. Fully sleeved cables reduce cable clutter and improve airflow management inside the chassis. The use of standard 3-pin connectors ensures broad compatibility with most fans and controllers that accept DC-driven fan inputs.

Suitable for

• Connecting two 3-pin case or CPU fans to one motherboard fan header
• Systems with limited fan headers where additional fans are needed
• Custom builds and upgrades that require neat cable routing

How to use

Connect the single end of each Y-cable to the motherboard or fan controller header and plug up to two 3-pin fans into the dual ends of the cable. Verify that the fans are securely seated and the connectors are aligned with the header pins. After connecting, power on the system and check fan operation in BIOS or with monitoring software to confirm both fans are detected and spinning.

Recommendations

Use the NA-SYC2 only where the combined current draw of the two connected fans does not exceed the rated current of the motherboard or controller fan header. Monitor fan speed and system temperatures after installation to ensure reliable operation.
