    i buy this 2 days ago, everything was ok, but i've got one problem about PWM fan, smart fan control on BIOS is not work, when cpu idle/load, my cpu fan not go higher or lower, all i can do is set my pwm fan to speedup fan rpm manually (i prefer 1700rpm and it stay on 1700 rpm when idle or load state)

    this is very annoying to brand new mobo like this, my CM seidon 120XL work perferctly in my old mobo, Gigabye 78LMT s2p. never had this issue Before.

    i connect 2 pwm fan to CPU fan header Via Y splitter as before.
    and pump to Sysfan1 (4 pin ) and try to swap this to other (3 Pin )

    Result still same. fan speed, not going up /lower depend on CPU load.


    Any help will be appreciated,

    the smart fan control should have an option for control type, the options should be AUTO, VOLTAGE, PWM
    Make sure you have it set to PWM as auto may not be working correctly

    Hi

    motherboard bios up to date?
    have target temprature setup
    have min and max fan speed sliders equal [set 50/50 to test]

    "Fan control field
    This motherboard provides a fan speed control feature call “Smart Fan Control”.
    Smart Fan Control automatically controls fan speed depending on the current CPU
    temperature and to keep it with a specific operating speed. When the current CPU
    temperature is over the maximum temperature, the CPU/ system fan will run at
    the maximum speed. When the current CPU temperature is under the minimum
    temperature, the CPU/ system fan will run at the minimum speed. In this field, you can
    set the CPU and system fans’ speeds and target temperatures."
