Table to list temperature threshold levels for 4 speeds of fan settings. Depending on the temperature level, the fans run at diffrent speeds of RPM. There are 4 levels of temperature settings for 4 fan speeds (low, medium, medium-high, high). This table is applicable to only those modules with temperature sensors. For each row, there are 2 temperature threshold values. The high value, if reached causes the fan to run at next high level speed and when it reduces the below the low value, the fan runs at next low spped.
