Dear, I have two simple but important question for my B450M Pro4-F

1) The maximum current output CHA_FAN1 can be used?
2) Seems CHA_FAN2 cannot control the fan speed. Always full speed?

Regards.

Dear Darigaz,

Greetings, this is ASRock TSD.

Regarding question 1, the maximum current of CHA_FAN1 is one ampere.
Regarding question 2, CHA_FAN2 support 4-pin fan only.
If 3-pin fan is used, the fan speed cannot be controlled and only run at full speed.

Thanks!

All the best,
ASRock TSD
