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!
