Default Q about real temp by intel and CPUID monitor

Just put together a box last week and ive been playing around for an everyday usage OC thats not hot (also trying to find a good OC for when I need it). I came upon Real Temp by Intel today and compared it to CPUid monitor. Core temps seem to be around 10C cooler with the program from Intel. Whats your experience and do you have more info on who is more accurate. I included a screen shot.

Cheers Canucks

The thing about core temperature sensors is that they do not report actual temperatures, but the difference in temp from max (TjMax - short for Thermal Junction Maximum). The problem arises in that Intel does not publish TjMax for their chips. HWmonitor probably uses a TjMax of 105 for your chip, while Intel's shows a TjMax of 95.

So when the temp sensors report back a difference of say 65 from TjMax, HWmonitor says the temp is 40 while the Realtemp prog reports 30.

Which one is correct? If the RealTemp program is the most current version (say released after the 45nm chips announced) it probably is accurate. After all, Intel program, Intel chip, right?

This is the first time I've heard of this program, going to try to find it now.

yeah its a new program I found it at Real Temp - New temp program for Intel Core processors - XtremeSystems Forums

thats what i figured intel + intel = should be right

Wow....Real Temp is reading approx. 10C lower! Is this to be trusted?

Maybe test out CoreTemp and SpeedFan along with it to see what other mainstream programs are coming up with?

Realtemp is accurate for the new 45nm chips, not sure what it will report with the older 65nm's though.

Hmm. Did some more digging. This is NOT an program released by Intel. This is based on someone taping a temp probe to a chip and trying to work back from there.

I'm very skeptical of this approach. The sensors measure the CORE temperature, not the heat spreader temp.

While we are all fascinated with the absolute temperature numbers (My cpu runs at 48 degrees under load), maybe we should be more interested with the delta TJ Max or headroom. ( i.e. at load, my cpu runs 17 degrees cooler than TJ Max)

All these programs (Coretemp, Everest, HWMonitor, RealTemp) work on assumed TJ Max numbers and are best guess approximations by the programmers

In short, believe the higher number for now
