Up to 54W via S-ATA and 24W via 4-pin
When powered via it’s S-ATA interface (for 12V fans only), the NA-FH1 can run fans with a combined power draw of up to 54W. When using the 4-pin PWM input only (for 5V or 12V fans), the maximum power draw can go as high as 24W.
Caution: Do not place directly on hard disk drives, keep at least 5cm distance. When powering via the 4-pin input from a PC motherboard, please check your motherboard manual for the maximum current of the fan header and make sure not to exceed it.
