" rel="nofollow - Hello so today I purchased 4 corsair LL120 fans and I'm trying to figure out what's the best way to hook them up. I was thinking about splitting CHA_FAN1 and CHA_FAN2. The fan Rate Current is 0.3A and I can't find anywhere how much the CHA_FAN is... I'm assuming 1A like my other asrock motherboard, would that work? Or should I just get a pwm fan hub and run that from CHA_FAN1?

Yes I believe the maximum CHA_FAN current per connector is 1amp on the z370 boards though would be best to stay below that as far as possible. I would think you will be ok piggy-backing 2 of the fans off one CHA_FAN connector, I did that with 2 Rosewill fans but they only draw .2A (200mA) each.
