P67A-UD3-B3 software fan control

[pinkythegreat]

Hello,

I am trying to control my 92mm Delta PWM fan (connected to the 4 pin sys_fan2 header) and the Intel stock fan through SpeedFan and EasyTune 6, but the speeds doesn't change if I try to manually set them. The only thing that works is the Smart Fan feature in EasyTune, but it controls only the CPU fan.

BIOS Settings:
CPU Smart FAN Control - Manual
Slope PWM - 0.75 PWM value / C
CPU Smart FAN Mode - PWM

I have the latest BIOS version.

What am I doing wrong?

Oh, I wrote the wrong board model (facepalm)

Actually it's P67-DS3-B3 rev. 1.0
F5 BIOS version. All settings set to default.
