Hi,

I have a Cisco 2921 Router with actually no clients working on it but the CPU temperature is 76 degree celsius. Is this normal? I think this is too hot.

My room is aircondishened to 21 degree celsius. What can I do?

Thanks a lot

Sebastian

Include the complete "show environment".

That Iwill tell you if the values are normal or not.

seems a bit high but depends on cpu load, what is the speed of the fans?

My 2921 is humming around @ 20-30% cpuload and look fine.

You can try updating IOS.

Thanks Paolo,

but well, I think 76 celsius is not normal especially with 0% load... maybe upgrading could solve the problem. does somebody has any other idea?
