CPU0: Temperature above threshold, cpu clock throttled help
 

under load my centos crash
any idea the cpu fan its ok

this is the messages in the syslog :

Can you use lm_sensors?
What's the Centos version that you're using?
uname -a?
Have you checked that there is good airflow for CPU fan?

I'd first try powertop to see if it really gets throttled if you don't have to jump thru hoops to install it.

the cpu fan its ok and spining very well and the air flow good as well maybe something in the bios ?

i install the lm_sensoers by yum install

how do i use it

Can't access procfs/sysfs file
Unable to find i2c bus information;
For 2.6 kernels, make sure you have mounted sysfs and libsensors
was compiled with sysfs support!
For older kernels, make sure you have done 'modprobe i2c-proc'!

Try to run You can use this and this guide for help.
Do you have non SMP kernel installed?If so,try to run it.

hi

i have replace my cpu fan and now all is good :

by the way what is Temp3 ???


and 100x for those that help me

Temp3 could be related to power supply temperature,but it can depend on the motherboard,so check your mobo manuals or something related.
