You should be able to pull temps from the C9200 if you SNMP walk the following OID
1.3.6.1.4.1.9.9.91.1.1.1.1.4
The first four values should correspond to the temperature values of the 4 sensors.

You may also need to adjust the sensor alarm thresholds on your NMS to match with the Cisco defined ones in the switch.
Hopefully this is helpful
