Fan Speed
(RPM)
A properly functioning fan is an essential component (along with a sufficiently
ventilated, cool operating environment) in order for the device to stay within the
temperature threshold. Each fan has a sensor that is capable of detecting and
reporting if the fan speed falls below the threshold shown.
Current This field displays this fan's current speed in Revolutions Per Minute (RPM).
MAX This field displays this fan's maximum speed measured in Revolutions Per Minute
(RPM).
MIN This field displays this fan's minimum speed measured in Revolutions Per Minute
(RPM). "<41" is displayed for speeds too small to measure (under 2000 RPM).
Threshold This field displays the minimum speed at which a normal fan should work.
Status Normal indicates that this fan is functioning above the minimum speed. Error
indicates that this fan is functioning below the minimum speed.
Voltage(V) The power supply for each voltage has a sensor that is capable of detecting and
reporting if the voltage falls out of the tolerance range.
Current This is the current voltage reading.
MAX This field displays the maximum voltage measured at this point.
MIN This field displays the minimum voltage measured at this point.
Threshold This field displays the percentage tolerance of the voltage with which the switch still
works.
Status Normal indicates that the voltage is within an acceptable operating range at this
point; otherwise Error is displayed.
Poll Interval(s) The text box displays how often (in seconds) this screen refreshes. You may change
the refresh interval by typing a new number in the text box and then clicking Set
Interval.
Stop Click Stop to halt statistic polling.
