Intel TAT / CoreTemp / IDCC all different temperatures....

[GGuyZ]

Technically it's not a "fix" just an adjustment of the Tjunction value from 85C to 100c for E4300s which will mean CoreTemp will read 15C hotter now.

Does anyone know what the Tjunction value should be for E4300s?

This does not make sense at all. Since Tjunction temperature does not exist in desktop processors, why would a fix be required? If you are already assuming that a Tjunction temperature exists(which is fault assumption too, as we all agreed), why not use the same Tjunction for E4xxx as well as E6xxx. I can understand why reporting C2Qs as 100c Tjunction makes sense, but I don't understand this logic with the E4300.

This would confuse many users that will now believe their E4300 operates at a much higher temperature. If any fix was to be applied, then it should be on TAT itself. Or instead, reporting only the DTS value(as fgw suggested) might be a better solution.

In RD600 cpu throtlles @ 85c via smartguardian. Shutdown temp set in bios also reads same temp. this is not the same temp that Coretemp displays(61c).

So, unless it's the bios @ fault on RD600, Coretemp is not reading correctly. I have same issue too, reading 19c idle in 25c ambient, using AIRCOOLING.

this being said, coretemp reports same temp across many different boards for same cpu, when voltages/cooling are the same. Although the temp may not be perfectly accurate, it's the best we got ATM.

This is very fishy and may damage the integrity of the conclusions which we all now believe in. While the absolute temp reading CT gives may be incorrect in many cases, it should always start throttling at 85C with C2D cpus, and 100C on C2Q cpus and some E4xxx. Obviously this is not real temperature, but it does indicate the throttling point. If this is indeed so, how is it possible that this guy encountered throttling at 61c in Coretemp?
