My general impression of lm_sensors is that you are lucky to get sensible numbers from most things in lm_sensors. Most consumer motherboards get built to save the manufacturer money, so things don't get connected. If a fan records a speed, it is probably accurate, but for everything else I disbelieve most readings. So, if you can get a config that is better, all well and good - but do not hold your breathe. On my own boxen I take the measurements that do not look outrageous (and are relevant - the temperature of the PCI adapter might be accurate, but mostly I care about CPU temperatures), and ignore the rest (I alias 'sensors' to a string of commands to only show what I think might be sensible readings ). > intel5500-pci-00a3 > Adapter: PCI adapter > temp1: +36.5 C (high = +100.0 C, hyst = +90.0 C) > (crit = +110.0 C) > > asc7621a-i2c-0-2e > Adapter: SMBus I801 adapter at 3000 > in0: +1.08 V (min = +0.00 V, max = +3.32 V) > in1: +1.18 V (min = +0.00 V, max = +2.99 V) > in2: +3.22 V (min = +0.00 V, max = +4.38 V) > in3: +5.07 V (min = +0.00 V, max = +6.64 V) > in4: +11.83 V (min = +0.00 V, max = +15.94 V) > fan1: 554 RPM (min = 0 RPM) > fan2: 0 RPM (min = 0 RPM) > fan3: 0 RPM (min = 0 RPM) > fan4: 0 RPM (min = 0 RPM) > temp1: -41.5 C (low = -127.0 C, high = +0.0 C) > (crit = -17.0 C) > temp2: +46.2 C (low = -127.0 C, high = +127.0 C) > (crit = +65.0 C) > temp3: +54.0 C (low = -127.0 C, high = +127.0 C) > (crit = +65.0 C) > temp4: +70.5 C (low = -127.0 C, high = +127.0 C) > (crit = +103.0 C) temp4 might be intended to monitor the CPU package (critical value is 3 degrees higher than the individual cores), or it might be totally spurious. > temp5: -41.5 C > temp6: -84.5 C > temp7: +96.2 C > temp8: +118.5 C Thos are probably not connected to anything. > > coretemp-isa-0000 > Adapter: ISA adapter > Core 0: +59.0 C (high = +80.0 C, crit = +100.0 C) > Core 1: +58.0 C (high = +80.0 C, crit = +100.0 C) > Core 2: +57.0 C (high = +80.0 C, crit = +100.0 C) > Core 3: +57.0 C (high = +80.0 C, crit = +100.0 C) > Those might be accurate, but they do seem high for an idle machine where the motherboard is at about 36 degrees. What generation of processor is this ? I don't grok xeon numbers, but I took a look at what intel say is compatible with that mobo, and if they are like desktop (SandyBridge 2nnn, IvyBridge 3nnn, Haswell 4nnn, Broadwell notionally 5nnn - in practice no Broadwell desktop CPUs have shipped, Skylake 6mmm) then this is just an nnn which implies it goes back to the days when intel was happy to burn power to run faster. If it _is_ a "run hot, run fast" machine, you might want to try a cpufreq driver such as ondemand : yes, that will slow down some things if your CPU supports it. ĸen -- This email was written using 100% recycled letters. -- http://lists.linuxfromscratch.org/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
