To read additional information about checking the current settings of the low and
high temperature thresholds for modules and fan speeds, see “Displaying
temperature thresholds for thermal planes and fan speeds” on page 67.
Changing temperature thresholds for thermal planes and fan
speeds on the B08S
The cooling system in the B08S includes six four-speed fans. The fans operate at
speeds of low, medium-low, medium, and high. In general, each fan speed, except
for low, has a low and high temperature threshold associated with it as shown in
Figure 30 on page 63. The low fan speed has a high temperature threshold only.
