The NA-SYC1 is a fan accessory set consisting of two fully sleeved NA-YC1 Y-Cables for 4-pin PWM fans. The NA-YC1 Y-Cables make it possible to run two 4-pin PWM fans on a single fan header and to let the mainboard control the speed of both fans simultaneously. Multiple NA-YC1 can be daisy-chained to control more than two PWM fans via one header.

Warning:
Common mainboard fan headers support up to 9.6 or 12W (check your mainboard manual for detailed information). Please thus make sure that the combined power draw of the fans connected to one fan header using NA-YC1 adaptors does not exceed this value!

LOADING...

The Noctua NA-SYC1 is a two-pack of black 4-pin Y-splitter cables for PC builders who want to connect and control two PWM fans from one motherboard fan header; only one fan’s RPM signal is sent for monitoring.

Recommended For

  • PC builders adding a second case fan near an existing fan location who want both fans controlled from one motherboard PWM header.
  • Dual-fan CPU-cooler or radiator users who want both PWM fans to follow the same motherboard fan curve while using one header.
  • PC builders with both 3-pin and 4-pin fans who need a splitter that supports either connector type; the fans share the header’s control signal.
  • Builders who want a short, black-sleeved cable to keep a two-fan connection neater inside a PC case.

Real-World Use Scenarios

  • When a dual-fan CPU cooler has two PWM fans but only one convenient CPU fan header, connect both through the splitter so they follow the same motherboard fan curve; the motherboard reads RPM from one fan.
  • When adding a second case fan near an existing one, use one motherboard header for both PWM fans; they respond to the same control signal instead of needing separate headers.
  • When a PC build has more fans than available motherboard headers, use the included splitters to group compatible PWM fans under shared control; check the motherboard manual to ensure their combined power draw stays within the header limit.
  • When fitting a radiator with two PWM fans, connect them to one header so they share the same motherboard speed control; only one fan's RPM is reported, so the reading does not show both fans separately.
  • When keeping a black-themed PC build visually tidy, use the sleeved black splitter cables to connect nearby fans without adding a conspicuous light-colored cable.
