Different driver. Centos 6.4 uses the coretemp driver which gets the

quite old when it comes to kernel version, and so is its coretemp

The displayed temperatures in your version are all wrong; the
maximum
temperature for Atom 330 is 125 degrees C, not 90 degrees C.
You'll have to add 35 degrees C to the displayed temperature.
You could either update the coretemp driver to a later version to
fix this, or add the offset to /etc/sensors3.conf.
Note that CPU temperatures are notoriously unreliable.
"Inaccurate in the low temperature range" is a better way to describe
the situation IMHO. The coretemp values are reliably telling the user
when the temperature gets too close to the high limit.

Well, I'm aware of that, what I want to know is when the fan fails,
these 40mm fans are not that reliable, unfortunately.
Not sure if you can use the cpu temperature to predict if the fans are
working
or not. The CPU can get pretty hot under load, even with the fans working.
Your initial e-mail showed the fan speeds as 0. Are they broken or turned
off
or not connected to the fan speed sensors ?
Guenter
Haven't got a clue why it says that they are 0, they definitely work now
(changed the fans today),
They are 3-pins and connected to the correct header.
Do you get a non-zero speed reported after replacing the fans ? If the reported
speed is still 0, I am not sure I understand what is going on.
