Hi forum members, maybe you could help me with this one, I have the above problem on my new motherboard as I cannot seem to be able to set the fan_cha2 speed in any way other that the one already preset, my bios is the last one 3.00, I did run fan tuning in bios and while for fan_cpu and fan_cha1 I can see an option as PWM, for fan_cha2 there?�s none. No pwm control for cha_fan2 is annoying as case fan attached to it runs full speed all the time,thus noise.

Tried to tune it with F-Stream utility, the fan speed is detected at ~ 1350 rpm for all percentages from 10% to 90%.

Currently fan_cha2 as setting, is set for mb temp detection , and profile setting is Silent profile.

Thank you,
