•
Two remote thermal diode sensors for direct monitoring of processor temperature and
ambient temperature sensing
•
Power supply monitoring of five voltages (+5 V, +12 V, +3.3 VSB, +1.5 V, and +VCCP)
to detect levels above or below acceptable values
•
Thermally monitored closed-loop fan control, for all three chassis fans, that can adjust
the fan speed or switch the fans on or off as needed
•
