The NA-SYC1 chromax.white is a fan accessory set consisting of three NA-YC1 y-cables that make it possible to run two 4-pin PWM fans on a single fan header and to let the motherboard control the speed of both fans simultaneously. Multiple NA-YC1s can be daisy-chained to control more than two PWM fans via one header. The NA-YC1’s 4-pin connectors are compatible with both 3-pin and 4-pin PWM fans, but PWM control is only supported with 4-pin fans. Thanks to the yellow sleeving, the cables are ideal for creating PC builds with neat, focused aesthetics and are a perfect match for Noctua’s chromax edition fans.
Caution
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.
