difference between temperature shown by Bios and sensors (Examined/Solved - lm_sensors 2.5.0 I2C 2.5.0 Linux 2.2.15)
|Reported by:||contact||Owned by:||somebody|
okay, this is more a question, but a bug report, but i hope it is okay !
I have compiled lm_sensors into kernel 2.2.15, so i do not have to load modules,
it's easier ;-) But if i use sensors i get about 31-31C for the CPU, after a
certain time of no activity on the machine. If i reboot instantly and go into
the Bios i always see > 40C for the CPU. I can't imagine that the CPU heats up
so much in a few seconds, so why is there such a gap between the value shown by
the Bios and sensors ? Which value is more reliable ?
Thanx in advance !

lm_sensors and I2C 2.5.0 compiled into kernel
--- Our package reports the 'real' temperature.
BIOSes often add a 'fudge' factor of 5-10C to account for
the fact that the sensors are a small distance away from the CPU.
If you would like to add a fudge-factor yourself you can do
so inside the configuration file /etc/sensors.conf.
