When syslog messages display a change in fan speed, you can identify which sensors triggered the
change by checking show chassis and show fan-threshold command output and looking for
sensors with temperatures near threshold
show chassis, show fan-threshold, and fan-threshold commands.
NOTE
A "thermal block" refers to the group of high and low thresholds for all fan speed levels.

Temperature threshold information for modules and fan speeds
Displays...
The temperature threshold information for the various modules. The
<module> parameter indicates the following:
•
MP – The active management module
•
STANDBY_MP – The standby management module
•
SNM – The switch fabric module
•
LP – An interface module
The current setting of the low and high temperature thresholds for the low,
medium, medium-high, and high fan speeds.

Table 37 on page 236, the low fan speed for each
module does not have a default low temperature threshold value,
nor can you configure this value. The "-1" value that appears in the
Fan Speed Low field for each module is a Brocade internal value
only.
