The problem is that Tjunction or TjMax is not properly documented by Intel so individual software developers can not write temperature monitoring programs that are 100% accurate across their entire line of processors. It's a guessing game and the only company to blame is Intel.
The calculation is simple:
core temperature = Tjunction - DTS
Intel documents how to read the digital thermal sensor ( DTS ) value but does not document how to read the Tjunction value which is needed. Without knowing the correct Tjunction it is impossible to calculate an absolute core temperature value. One person from Intel implied that there is no way to read Tjunction from a processor which may or may not be true.
An assumed Tjunction of 85C for the E4300 results in idle temps below ambient which is impossible so it is assumed to be 100C.
Unfortunately the developer of CoreTemp also assumed that the new E6300 / E6400 cpus built on the same Allendale core must also have a Tjunction of 100C but TheRapture proved that to be wrong in his above post.
Here's what seems to be true:
Tjunction:
E4300 = 100C
All other presently available Core 2 desktop processors have a Tjunction of 85C. This includes the original revision B2 Conroe based processors as well as the E6300 / E6400 revision L2 processors.
Laptop processors have a Tjunction of 100C. This includes all Core Solo, Cord Duo and Core 2 Duo mobile processors:
T1300, T1400, T2300 to T2700, T5500, T5600, T7200, T7400, T7600
CoreTemp 0.95 works properly on all processors except the revision L2 E6300 / E6400.
If you have a revision L2 E6300 / E6400 then use CoreTemp 0.94.
coretemp 0.95 kann nicht stimmen, weil dann hätte ich schon 50°C idle mit ner wakü und 75°C unter last.
bei den 4xxx Modellen wird aber weithin gesagt das0.95 richitg ist. Evtl. mal den Kühler neu aufsetzten?
