Thank you!!
You don't. Only CHA_FAN1 is able to be controlled, and only if using a 4-pin fan. CHA_FAN2 doesn't support fan control. I use a 3-way fan splitter that cost around $5 on newegg.

I have an Asrock AB350M PRO4 motherboard with 2 chassis fans. The 1.
one connected to my cha_fan1 4 pin connector with a 3pin cable,
it works fine. I can controll it's speed.


But the other connected to my cha_fan2 3pin connector with a 3pin cable running at full speed and not even appear at A-tunning utility at FAN tuning(but the program can see it bcs at the 1st picture it shows it's rpm).


How can I change the cha_fan2 speed?

Thank you!!
