Using latest version from link above I've got:
Found `Nuvoton WPCD377I Super IO'
    (no hardware monitoring capabilities)

removed "lm85" and "i2c-i801" modules

Here are 2 consecutise "sensors" run:

# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +73.0°C  (high = +74.0°C, crit = +100.0°C)  ALARM

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +68.0°C  (high = +74.0°C, crit = +100.0°C)

coretemp-isa-0002
Adapter: ISA adapter
Core 2:      +69.0°C  (high = +74.0°C, crit = +100.0°C)  ALARM

coretemp-isa-0003
Adapter: ISA adapter
Core 3:      +71.0°C  (high = +74.0°C, crit = +100.0°C)  ALARM

# sensors
coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +72.0°C  (high = +74.0°C, crit = +100.0°C)  ALARM

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +67.0°C  (high = +74.0°C, crit = +100.0°C)

coretemp-isa-0002
Adapter: ISA adapter
Core 2:      +67.0°C  (high = +74.0°C, crit = +100.0°C)  ALARM

coretemp-isa-0003
Adapter: ISA adapter
Core 3:      +70.0°C  (high = +74.0°C, crit = +100.0°C)  ALARM

PS: lm-sensors was installed from repository
# sensors -v
sensors version 3.0.2 with libsensors version 3.0.2

PPS: I'm having some problems with the temperature, it reached even 100
