This is surprising and might be where the alarm comes from. What output do
you
get if you load the coretemp driver ?

coretemp-isa-0000
Adapter: ISA adapter
Physical id 0: +38.0 C (high = +81.0 C, crit = +91.0 C)
Core 0: +36.0 C (high = +81.0 C, crit = +91.0 C)
Core 1: +35.0 C (high = +81.0 C, crit = +91.0 C)
Core 2: +35.0 C (high = +81.0 C, crit = +91.0 C)
Core 3: +34.0 C (high = +81.0 C, crit = +91.0 C)
Core 4: +37.0 C (high = +81.0 C, crit = +91.0 C)
Core 5: +38.0 C (high = +81.0 C, crit = +91.0 C)

> PCH_CHIP_TEMP: +0.0 C
> PCH_CPU_TEMP: +0.0 C
> PCH_MCH_TEMP: +0.0 C
> intrusion0: ALARM
> intrusion1: ALARM

Are those not connected ?

The intrusion headers are not connected, also, I have not dug into it but
when you try to ignore the PECI or those PCH* lm_sensors seems to ignore the
rule.

sensors3.conf:
ignore PCH_CHIP_TEMP
ignore PCH_CPU_TEMP
ignore PCH_MCH_TEMP

$ sensors |tail -n 4
PCH_CHIP_TEMP: +0.0 C
PCH_CPU_TEMP: +0.0 C
PCH_MCH_TEMP: +0.0 C

Ignoring intrusion works though:
ignore intrusion0
ignore intrusion1
