how to increase cpu temparature linux

I was using psensor and want to confirm that whether the CPU temperature can be increased  through software or not.

Googling gave the first link

Yes, it is possible to increase CPU  temperature.There are various ways to achieve this.

we can use "dd" or a stress generating tool like "stress"

I tried installing in Centos 6.4, 64 Bit.

yum install stress.x86_64


As soon as I issued this command,

stress -c 40

CPU temperature got increased from 40 C to 58 C , core wise .
I measured with the help of psensor tool.

The above command mean, to stress all your CPUs  with 40 threads each running a Complex  Computation.

My System is 2 GB RAM, Intel(R) Core(TM)2 Duo CPU  E7600  @ 3.06GHz with 2 CPU Cores per CPU.

This is the Graph of system prior to run stress.

Core 0: [ Time Vs Temperature]




Core 1 : [ Time Vs Temperature]



After Generating Stress,the graph is shown here.

Core 0 : [ Time Vs Temperature]



Core 1 : [ Time Vs Temperature]
