Linux - CPU Temperature above threshold

Hi ,

I have ProLiant DL380 G4 server running with Linux on it

Getting following error in syslog.

Mar 15 16:30:51 BSICMDBDR kernel: CPU3: Temperature above threshold
Mar 15 16:30:51 BSICMDBDR kernel: CPU2: Temperature above threshold
Mar 15 16:30:51 BSICMDBDR kernel: CPU2: Running in modulated clock mode
Mar 15 16:30:51 BSICMDBDR kernel: CPU3: Running in modulated clock mode

Any idea what to do about this pleas?

Thanks and Regards
Rajeev

CPU2 and CPU3 are not receiving enough cooling. The CPUs are slowing themselves down to prevent overheating damage.

Things to check:

- Is the server room too hot? (See the server's manual for specifications.) Increase cooling if necessary.

- Is the airflow into or out of the server blocked by dust, dirt or unorganized cables? Clean & reorganize if necessary.

- Is there dust build-up in the CPU heat sinks? (This might happen if the server is in a very dusty environment.)

Fan failure is another option?
