Re: sensors/temps question
Sorry to hi-jack...
Where I can I find a decent priced PCI card that does temps (tethered to place on anything or just for case)??
* And is recognized by sensors-detect? |

I don't have my PC with me, it's in the shop (don't remove your CPU and walk around barefoot on carpet), but yes I noticed the same thing it reports temp1 (CPU), temp2 (motherboard), core1 and core2.... Core1 and Core2 always seem to be lower than "CPU" temp. CPU temp seems to match up with what the BIOS says.
It's an AMD AM2 dualcore, if that matters.

Yup I am pretty sure its exactly as thompson42 says. On my system I always see at least a 5-6C difference in CPU vs core temperatures:
Sys Temp: +26.0°C (high = -104.0°C, hyst = -67.0°C) ALARM sensor = thermistor
CPU Temp: +26.0°C (high = +80.0°C, hyst = +75.0°C) sensor = diode
AUX Temp: +26.5°C (high = +80.0°C, hyst = +75.0°C) sensor = thermistor
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +33.0°C (crit = +100.0°C)
coretemp-isa-0001
Adapter: ISA adapter
Core 1: +32.0°C (crit = +100.0°C)
coretemp-isa-0002
Adapter: ISA adapter
Core 2: +33.0°C (crit = +100.0°C)
coretemp-isa-0003
Adapter: ISA adapter
Core 3: +32.0°C (crit = +100.0°C)

Chugging along on 2x 6016/768k DSL Extreme DSL lines and one 6016/768 ATT DSL DIrect line as well as one 10mb/1mb Charter cable line for a combined total of just over 26 meg download and 3 meg up (after overhead). yay! |

Like you, I understand that the coretemp readings are taken from within each of dual cores in the CPU, while the ACPI readings are taken from sensors on the motherboard. My coretemps are usually lower than one of my two ACPI readouts (cores 35C, 34C, ACPI 39C 27C). This doesn't seem too odd to me, since the CPU has that big fan mounted directly on top.
If I max out both cores (two shells, each running yes>/dev/null), then the cores (56C 56C) are hotter than the ACPI temps (40C 43C). |

At the moment its reading:
coretemp-1
core 1 - 42C
coretemp-2
core 0 - 44C
ACPI
TZ01 51C
TZ00 51C
so no, it doesn't always track as it showed in my first post. Sometimes on of the coretemp readings happens to match one of the ACPI readings, but other times they don't. What does always seem to be the same are the two ACPI readings. |

the ACPI is reporting some actual sensor reading, which (if it continues to track like you show there) is "coretemp2"
What sensor the ACPI uses is up to the bios folks.

|  What is the difference between the coretemp readings and the acpi readings for cpu temps? I'm assuming the coretemp readings are taken right from the cpu core, but if that's correct I would have expected those to be higher than the acpi readings.
My readings at the moment are:
coretemp1 - 38C
coretemp2 - 47C
TZ01 - 47C
TZ02 - 47C |
