Acessório de sistema de refrigeração Noctua NA-SYC1, preto, 150×111×29 mm, 60 g

The Noctua NA-SYC1 is a set of two fully sleeved NA-YC1 Y-cables designed for 4-pin PWM fans. Each cable allows two PWM fans to be connected to a single motherboard fan header so the mainboard can control the speed of both fans simultaneously. Multiple NA-YC1 cables can be daisy-chained to control more than two PWM fans from one header, making the NA-SYC1 a compact accessory for expanding fan connections while maintaining synchronized speed control.

Advantages

The fully sleeved design provides durable insulation and a neat appearance, while compatibility with standard 4-pin PWM headers ensures reliable speed control by the motherboard. The compact dimensions and low weight make installation simple and unobtrusive in most PC builds. Black colouring matches common system components for an integrated look.

Suitable for

• Connecting two 4-pin PWM case fans to a single motherboard fan header
• Daisy-chaining multiple PWM fans for synchronized speed control
• Expanding fan connections in compact or multi-fan PC builds

How to use

Plug the single end of each NA-YC1 Y-cable into an available 4-pin PWM fan header on the motherboard. Connect up to two 4-pin PWM fans to the dual outputs of each Y-cable. If needed, plug additional NA-YC1 cables into the same header to daisy-chain more fans. Verify in the BIOS or fan control software that the motherboard detects the connected fans and controls their speed via PWM.

Recommendations

For proper fan control, use the NA-SYC1 with PWM-capable 4-pin fans and ensure the motherboard header supports multiple-fan loads. Check motherboard fan header current limits before connecting many fans to a single header to avoid overloading.
