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.]]> Tue, 25 Apr 2017 00:21:34 +0000 https://forum.asrock.com/forum_posts.asp?TID=4863&PID=27874&title=ab350-pro4-chasis-fan1-speed-control-not-working#27874 <![CDATA[ab350 pro4 chasis fan1 speed control not working : there is no option for choose...]]> https://forum.asrock.com/forum_posts.asp?TID=4863&PID=27437&title=ab350-pro4-chasis-fan1-speed-control-not-working#27437 Author: boltless

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

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.]]> Sun, 16 Apr 2017 23:23:25 +0000 https://forum.asrock.com/forum_posts.asp?TID=4863&PID=27388&title=ab350-pro4-chasis-fan1-speed-control-not-working#27388 <![CDATA[ab350 pro4 chasis fan1 speed control not working : ab350 pro4, the 3-pin (DC mode)...]]> https://forum.asrock.com/forum_posts.asp?TID=4863&PID=27363&title=ab350-pro4-chasis-fan1-speed-control-not-working#27363 Author: boltless

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.
