It keeps slowly=20 varying in the 72-76 degrees C range. I'm afraid hardware isn't really my domain, so even though I do have the=20 document it doesn't make much sense to me. What I do gather from from=20 the technical specs=20 (http://download.intel.com/support/motherboards/desktop/dg31pr/sb/e14051001= us.pdf)=20 is that there are thermal sensors in the CPU(s), the I/O Controller Hub=20 (ICH7) and the Graphics and Memory Controller Hub (GMCH). If I=20 correlate that information with the sensors-detect output and eliminate=20 the core temperatures, it seems that the 76 degrees C is in the ICH7=20 (though I could be totally wrong). In any case, from experience, is a temperature of 76C in the ICH or the=20 GMCH a cause of concern? If this is in the normal range for=20 motherboard temperatures I'll stop worrying about my system running hot=20 right now :) If it looks high, I'll ask my hardware supplier to check=20 the board out for faults.
