Cooling System Accessory Noctua NA-SAC1

The Noctua NA-SAC1 is a set of three fully sleeved NA-AC1 3‑to‑4‑pin adapter cables that enable connection of standard 3‑pin fans to 4‑pin peripheral (Molex) power supply connectors. The adapters feature a loop‑through design on the 4‑pin connector so additional devices or further adapters can still be connected.

Advantages

The NA-SAC1 provides fully sleeved cables for improved durability and neat cable routing. Its loop‑through 4‑pin connector preserves the ability to chain other peripherals or adapters, and the adapters are compatible with standard 3‑pin fans, offering a simple and reliable means to power additional cooling devices from a PSU peripheral connector.

Suitable for

• Connecting standard 3‑pin fans to a PSU 4‑pin peripheral (Molex) connector
• Powering additional case fans when motherboard fan headers are limited
• Cleaner cable routing where sleeved adapters are preferred

How to use

Plug each 3‑pin fan connector onto the 3‑pin end of an adapter cable and insert the adapter's 4‑pin peripheral connector into a matching PSU peripheral (Molex) outlet. Ensure connectors are fully seated. If required, use the loop‑through socket on the adapter to connect another peripheral or adapter. Verify fan operation after powering on the system.

Recommendations

Use the NA-SAC1 adapters when PSU peripheral connectors are available and motherboard fan headers are occupied. Avoid forcing connectors; align pins carefully to prevent damage. Because these adapters convert to a non‑PWM 4‑pin peripheral feed, fan speed control may be limited by the power source—use only with compatible fans and configurations.
