Each of the three fan units cools an overlapped area in the hub covering 8 slots.
The slots covered by each fan unit are:
•Fan 1 - slots 1-8
•Fan 2 - slots 6-13
•Fan 3 - slots 10-17
These 3 areas have their own temperature sensors. Also, integrated into each
fan unit is a sensor that detects a stopped or slow fan condition.
The Controller module continually monitors all the sensors via the SCI. You can
display the status of the fans and the temperature of the 8260, using the
following DMM command:
