You'll need to dive into the registry (regedit.exe), navigate to HKLM\Software\PhenomMsrTweaker and add string values (names: 'Fan1', 'Fan2', 'Fan3'). Each string consists in an arbitrary number of control points separated by '|'. Each control point is defined by an integer specifying the CPU temperature (in °C) + ':' + fan speed in percent (another integer). Linear interpolation is used to connect the control points.
    For example: 'Fan1' = '30:50|40:75': The first fan (most likely the CPU fan) runs at 50% speed at temperatures <= 30°C, at 62.5% at 35°C and at 75% at temperatures >= 40°C.
    If at least one such string is found and a supported IT87xx controller is detected, fan management is enabled. If a fan's string is missing, it is run at 100%.
    An optional DWORD value named 'PwmRamp' may be used to transition slowly to other speeds. Its value specifies the maximum jump of each fan speed (again in percent) from one interval to the next (500 ms).
I just added the FAN1 value to my registry and upon reboot, I am very pleased with how it's working. So, now, kink, do you know which other fans PMt can control? Because SpeedFan normally could only control the one plugged into the CPU header, even though 3 headers are actually PWM rated on my board (790XT-UD4P, with Phenom 940 Deneb).

I would love to have it controlling the 2 fans in the other 2 PWM spots (the so-called "PSU" header and the "Sys1"). I guess I could add the values for FAN2/3 and see if it makes a difference, I'm just skeptical it will.

But regardless, thank you so much for going back to work on PMT (if I can so-abbreviate it) -- I love it, and my temps have never been so low! You rock!!
