Tcontrol works by reading "too low" when it's below a "certain temperature point" but then "too high" when above that same "certain temperature point". The temperature point looking at documents seems to be near 55C real Tcase.
Ok, so if I got it, 55C its the "breaking" point, Tcase(real temp)<55 Tcontrol read low temps. So my readings are "low" Tcontrol=CPU 57C; Cores 48C full load, can I make an logical conclusion that my Tcase<55C?

As you can see some posts before I got photos from my system running, the white fan is at 110CFM and blow air over PWM HS, and i feel the difference between PWM/CPU, I know is far from be accurate reading, but reflects the software reading difference values, in bios CPU temp reads 28 and PWM 45.
Only the MSI runned fine 2750 @1.3v.

Well, I have some temp probes cables, and still have an K7M board with pins to connect, so if I put the probe between CPU and the socket (I have one able to insert there, just don't know here), can I read Real temp in the K7M system?
