Hi Geoweb35,

Thank you for your post.

Here is the Z87 Pro4's fan header information for your reference.

CPU_FAN1: 1A, 4 pin fan header, can't control 3 pin fan speed
CPU_FAN2: 0.5A, 3 pin fan header, can control fan speed
CHA_FAN1: 1A, 4 pin fan header, can't control 3 pin fan speed
CHA_FAN2: 0.5A, 3 pin fan header, can control fan speed
PWR_FAN1: 1A, 3 pin fan header, can't control fan speed

In general, CHA_FAN1 can handle 3 Noctua NF-A12X25 PWM at the same time.

If you have other questions, please feel free to contact us.

Thanks,

All the best
ASRock TSD

Hi, how many Noctua NF-A12X25 PWM (0.14A) fans can i connect to CHA-FAN1 4pins header? i want to know the max amperage for the CHA-FAN1, this information is not included in motherboard manual. Can i connect 3x Noctua NF-A12X25 PWM in CHA-FAN1? thanks.]]> Tue, 18 May 2021 14:12:28 +0000 https://forum.asrock.com/forum_posts.asp?TID=18876&PID=87194&title=asrock-z87-pro4-fan-connector-amperage#87194
