ab350 pro4, the 3-pin (DC mode) fan speed of chasis fan 1 jumper is not adjusted.
chasis fans jumper 2 and jumper 3 have good speed control with 3-pin fan.

Can confirm. I found in a FAQ somewhere that chassis 1 does not work with 3 pin. Other fan connectors work fine with 3 pin.

there is no option for choose dc or pwm in bios.
according to faq.. just auto detect fan type in chasis fan 2, 3.

If you plan to adjust fan speeds according to CPU temperatures and your cooler's fan is PWM-controlled, you can connect cooler's fan to the problematic header (Chassis fan 1), and connect the case fan to CPU header, and change control method from PWM to DC. It's a dirty hack, but may work.
