Check and make sure your fans are working using the command "sh env".

All fans are ok, The fan is running high but that will be due over temp alarm. The inlet & chassis temps are okay, so not sure if this a bug in the IOS or a faulty sensor.

This has occurred on two routers in different locations with the same IOS both occurred shortly after a reload and recording the same 127c temp.
