Sun Fire v440 Over heat Problem.
Dear Team,
I need some expert advice to my problem.
We have a Sun Fire v440 in our customer Place. Server is working fine and no hardware deviations are found except one problem that processors generating too much heat. I have verified and found that the room temperature was 26-27 degree.
The tempearatures of the processors are also flctuating over the day. If we put a Fan behind the server,the temp decreases to 2-3 degrees . I think due to excess room temp,this overheat issue arises. Is my assumption correct or is there any other factorsare there which related to the overheat issue. Please suggest.
NOTE: No errors found in messages files also
i am sending the logs of the server for better understanding. these are the readings taken after 2 hours duration.

Hi,
I was asked to connect a KVM screen to a Sun Fire V440 last night so I connected it up but no joy and nothing on the KVM screen. I was told that a reboot may fix the problem so connected to the ALOM and rebooted. On the plus side, the KVM screen now works but I lost the ALOM connection.
