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.  Attention! 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!


  • Y-type splitter cables for running two fans on one fan header
  • Two 4-pin PWM fans can be controlled simultaneously via one PWM fan header; RPM speed signal of one fan is transmitted to the motherboard for monitoring
  • 4-pin connector supports both 3-pin and 4-pin fans
  • Black connectors and black cable sleeving for clean optics
