Remote diode 1. Might be ambient. > Which is the true cpu temp ? Core1 from K8temp or CPU temp from dme1737. What's the meaning of life? Who knows? No seriously, I can't speak for the k8temp but certain CPU types are broken and return bogus temp values. You might want to send the output of 'cat /proc/cpuinfo' to the list and have Rudolf M. take a look at it. For the dme1737 temps, either RD1 or RD2 can be the CPU temp, that depends on the board layout. It just happens that the current sensors.conf file labels RD2 as the CPU temp. But given the fact that RD2 (CPU) temp rises when you exercise the CPU and that it's the higher of the two is a strong indication that it is indeed the CPU temp. As for the accuracy of the reading, that depends on 2 factors which are controlled by the board manufacturer and BIOS implementation: 1) The conncted diode has to be of type 3904. If not, the reading will be bogus. 2) The temp offset needs to be initialized properly by the BIOS. If not, the reading will be off. Check out the following link for guidlines on how to calibrate/validate your CPU temp readings: http://www.silentpcreview.com/article191-page1.html > I ran a kernel compiling loop to 'burn' the cpu a little and both rose > about 8?C. > But is either a true figure ?
