It may also be worth checking that the sensors are actually reading
correctly. You can read them using the "sensors" command from the
lm_sensors package or by running:
grep . /sys/class/net/eth88/device/i2c-adapter:*/*-002e/temp*_input
Divide the numbers by 1000 to get temperatures in degrees celsius.
The "internal" temperature sensor (temp1_input) is in the LM87, which is
placed at the corner of the board away from the bracket and the edge
connector.
The "external" temperature sensor (temp2_input) is in the SFC4000.
