Fan speed and Vcore temp?

[Jayson201]

So I've noticed that my fans ramp up pretty quickly, and as does this new "vcore temp" that the Sabertooth 990fx shows. Used to have a board that didnt display that.
Anyway, the vcore temp is at any given time a good 10c higher than the actual cpu temperature. Which idles in current ambient temperatures at 40c.
The issue then is, my fans like to get loud and the way i have them set, they shouldn't get as loud as they do, UNLESS. the fan curve is following the vcore temperature and not the cpu temperature.
Vcore is obviously the vrm/power delivery area, and short of putting a fan on my side panel i don't know what to do to lower the temps or change the curve to follow a different temperature.
Anybody have an inkling of what im going on about?

On top of that, I don't feel I have any control of my fans from within the pc (At least not the cpu fans which runs at a constant 2300 or higher
