Try this.

Smart Fan Options - Disabled

CPU Fan Mode - this depends on fan type.
For a retail 4 pin Intel fan, it should be PWM.
For an aftermarket 3 pin fan, it should be VOLTAGE mode.

Then, try Speedfan from . (the speedfan download)

You can control the fans with Speedfan. Disabling the control
in the BIOS, means less chance for interference. It might in fact
work, that leaving it enabled in the BIOS, still allows Speedfan
to override it. But if you have problems, you can disable
the setting in the BIOS, to give Speedfan more of a chance to
adjust it.

Best guess,
