Many thanks Shoggy :
I imagined that it would be something like that ; a correction to the estimated value, by the impossibility of placing the probes in the best possible place , with regard to the real value .
For example, in CPU , if i can't put the probe in the best possible site ( below the die by example ) the value that will mark the probe, normally , will be below the real value .
Then , I must try to monitor with Everest , coretemp , Motherboard Monitor , etc....( ¿ what would be better for this task ? ) and try to get as much as possible to the real temperature in order to make that correction estimate ...............¿ what I've understood correctly ?
Greetings
