I installed a sensor reporting utility on my Ubuntu machine (a desktop machine) and it reports drastically different temperatures for the ACPI CPU reading and the ISA Core 0/Core 1 reading.
The ACPI says the CPU temperature is 31.5 C, but the ISA adapter reports the Core 0 is 55.0 C and Core 1 is 56.0 C.
Why do the "CPU" and "Core" temperatures differ? Are these sensors in different locations on the motherboard?
