Hi everybody

After a few years with phenom II X4 945 , I've now an FX6350 , working really fine. One little thing is disturbing me: On idle , temp (speedfan , or aida 64) jump from12° to22° in one second (12 and 22 just for example) then in the same time , go down to 15°,then 20° ........

But with 100% CPU (aida cpu stress test) , after a few seconds , I have a real straight line 40° .

What is the meaning for this jumping idle temp ?

But when using phenom II with same bios , idle temp was always about 20° , sometimes moving from 20 to 21 , or 20 to 19 . I never had 10° jump !?

Because newer processors are better at saving power when not needed. It's normal.

ok, thanks for these answers.

it's always better to know "the reason why".

Newer AMD processors have multiple "power planes" allowing both the CPU voltage and frequency to be altered based on load. This is why under low load the CPU/APU temp can literally jump 10 degrees almost instantaneously.

Technical ignorance is NOT a destiny it is a choice. Do your homework so that you can make technically informed decisions and not be duped by advertising hype or mis-information stated as fact when its not.
