I didn't know it's possible to switch to DC mode.
I will try it.

Thanks :)

Dear Guysmo,

 

Thank you for choosing ASRock.

 

Regarding your case, B250 Pro4 has 3 chassis fan, chassis fan2 and chassis fan3 can support 3-pin fan.

Chassis fan 2 can auto detect if 3-pin or 4-pin fan is in use.

Chassis fan 3 have to set to DC mode in BIOS, after setting to DC mode, 3 pin fan speed can be controlled.

Thank you!

Yours truly,

ASRock TSD

Hi,

I bought an ASROCK B250 PRO4 and I'm trying to control all fans, they all have 3 pins.
In BIOS, I found the menu to set silent or full speed mode but in any cases, fan speed doesn't change !
If it's not possible with BIOS, which software can do that ? (speedfan doesn't work)

Thank you for your time.
