" rel="nofollow - Hello everyone,

I'm considering the uATX Asrock H170M-Pro4 or -Pro4s for a new build.

Would an owner of either board kindly confirm if the case fan headers (CHA_FAN1 and CHA_FAN2) allow full UEFI control of 3-pin fan case fans?

Greatly appreciate your help, thanks!

Dear Tr0ed,

Greetings, this is ASRock TSD.

All fan headers including CPU and Chassis fan on H170M Pro4 and H170M Pro4S could support to control the fan speed when connecting 4-pin fan or 3-pin fan.

Please note that if you plan to connect a 3-Pin fan, please connect it to pin 1-3.

Thanks!

All the best,

ASRock TSD
