Different driver. Centos 6.4 uses the coretemp driver which gets the
temperature from the CPU directly. Unfortunately, Centos 6.4 is quite
old when it comes to kernel version, and so is its coretemp driver.
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 ?
