Cable extension Noctua NA-SYC1 CHROMAX.BLACK

The Noctua NA-SYC1 CHROMAX.BLACK is a set of three high-quality NA-YC1 Y-cable fan adapters finished in black sleeving, designed to let two 4-pin PWM fans run from a single motherboard fan header while keeping PWM speed control for both fans. Each adapter features standard 4-pin connectors that are compatible with 3-pin and 4-pin fans (PWM control requires 4-pin fans). The black sleeving provides clean visual integration in dark or monochrome PC builds and matches Noctua's chromax range.

Advantages

These Y-cable adapters allow synchronized PWM control of two fans from one header without altering the fan control signal, simplifying cable routing and reducing the number of occupied headers. The durable sleeving and molded connectors improve cable longevity and appearance, while the trio pack supplies multiple connections for multi-fan setups. The compact design supports daisy-chaining multiple NA-YC1 adapters to control more than two PWM fans from a single header where motherboard power limits permit.

Suitable for

• PC builds requiring synchronized fan speed control for two fans from one motherboard header
• Small form-factor systems with limited fan headers
• Systems aiming for clean, black-themed cable appearance
• Cooling setups where daisy-chaining multiple adapters is needed (observe motherboard power limits)

Key specifications

• Contents: 3 x NA-YC1 Y-cable fan adapters
• Connector type: 4-pin female to dual 4-pin fan connectors (Y-split)
• Compatibility: compatible with 3-pin and 4-pin fans (PWM control only with 4-pin fans)
• Colour: black sleeving
• Cable width/visible sleeve length: approximately 115 mm
• Daisy-chaining: supported for controlling more than two fans from one header

How to use

Connect the single end of an NA-YC1 adapter to a motherboard fan header and plug up to two 4-pin fans into the dual fan connectors. Ensure that the fans connected are 4-pin if you require PWM speed control; 3-pin fans will run at voltage-based speeds without PWM synchronization. Multiple adapters can be daisy-chained by connecting additional NA-YC1s to further fan connectors when you need to control more than two fans from one header. Always consult your motherboard manual to confirm fan header power limits and avoid exceeding the header's rated combined power draw.

Recommendations

Check the combined power consumption of all fans attached to a single motherboard header and compare it with your motherboard’s specified maximum for fan headers (commonly 9.6 W or 12 W). Use the NA-SYC1 CHROMAX.BLACK for balancing cable management and PWM control in multi-fan configurations, and prefer 4-pin PWM fans when precise speed control is required.
