fltProcessorUnitThermalNonCritical

This fault occurs when the processor temperature on a blade or rack server exceeds a non-critical threshold value, but is still below the critical threshold. Be aware of the following possible contributing factors:
   - Temperature extremes can cause Cisco UCS equipment to operate at reduced efficiency and cause a variety of problems, including early degradation, failure of chips, and failure of equipment. In addition, extreme temperature fluctuations can cause CPUs to become loose in their sockets.
  - Cisco UCS equipment should operate in an environment that provides an inlet air temperature not colder than 50F (10C) nor hotter than 95F (35C).
  - If sensors on a CPU reach 179.6F (82C), the system will take that CPU offline.
If you see this fault, take the following actions:
  - Review the product specifications to determine the temperature operating range of the server.
  - Review the Cisco UCS Site Preparation Guide to ensure the servers have adequate airflow, including front and back clearance.
  - Verify that the air flows on the Cisco UCS chassis or rack server are not obstructed.
  - Verify that the site cooling system is operating properly.
  - Power off unused blade servers and rack servers.
  - Clean the installation site at regular intervals to avoid buildup of dust and debris, which can cause a system to overheat.
  - Use the Cisco UCS power capping capability to limit power usage. Power capping can limit the power consumption of the system, including blade and rack servers, to a threshold that is less than or equal to the system's maximum rated power. Power-capping can have an impact on heat dissipation and help to lower the installation site temperature.
  - If the above actions did not resolve the issue, create a show tech-support  file and send back to me...!!!
