Real Temp - New temp program for Intel Core processors

Or is it the Tjmax value that we see under settings (100C for all cores on my copy of Realtemp) ?

That's right. RealTemp reads the value from Core i7 processors and uses that value as TJMax.

Intel did the play on words with TJ Target not necessarily being the same as TJMax when they released this information for the previous 65nm processors.

By having this information stored within each Core i7 processor it would be possible for them to have a different TJ Max value for each core and software could read that and adjust accordingly. So far, all I've seen used is 100 for this value for all Core i7 processors but maybe in the future Intel will use this capability.

As far as I know this value is only a TJ Target number and actual TJMax may be slightly higher.

Apparently my front intake fan has decided to fail which explains why Everest didn't list it in the screen cap. After manually encouraging it to crank over, it doesn't appear to have any impact on the closed case temps.

ptelles: It doesn't look like CPU-Z is reading the correct core voltage from your motherboard. Everest showing CPU1 at 1.21 volts is likely correct. Your testing shows that TJMax is not likely 100C. It also looks like Intel's TJ Target of 85C for your CPU would be too low.

Based on your testing, my best guess is that TJMax is likely closest to 90C. Intel says that TJMax is not an exact number but I think using 90C will get you accurate temperatures from idle to TJMax. That would put your reported temperatures above your room temperature at a similar amount to what rge found during his testing. rge tested a Dual Core, but based on power consumption at idle, a Quad would only be about 1C higher during this test. Your additional core voltage might also contribute another degree compared to rge's testing.

9C above your room temperature of 25C equals 34C. If you use TJMax = 90C, your reported idle temperatures are going to be right in the 34C range so I'd go with that.

Thanks Uncle. CPU-Z 1.49 apparently mistakes the empty second processor socket's vcore for that of the first processor.

Per your suggestion, I changed Tj Max to 90°C. I also determined that in fact my intake fan did not fail as I had originally thought. With the exception of the CPU cooler, all other fans were under BIOS control. Apparently the BIOS would randomly decide not to start the NB & intake fans at power-on.

I decided to disable BIOS fan control, add 3 exhaust fans to the left side of the case and increase my overclock from 2.83GHz to 2.9GHz.

I ran an eight hour Prime95 blend torture test. Real Temp reported a high of 54°C and a low of 37°C. Ambient room temperature for the duration of the torture test varied between 25.33°C and 27.11°C. Not bad eh? Your thoughts?
