i7 3770 "jumpy" temps

Hello,

I have owned a i7-3770 for over year now, and i have a asetek 570lx water cooler on it.

The idle temp is arount 28C
When i stress the cpu with prime95, or say, turn on a game ,the temps jump to 65-70C instantly, however, when i switch it off, even after running prime or some game for quite some time, the temps go back to 30-35C instantly, and then go back to idle temps within a minute.

I have changed the thermal paste a total of 3 times during the time i've owned this processor, and i can confirm that i have used the right amount of thermal paste each time, and the cooler is seated properly.

Is this normal? It has been like this since the day i got it.

Thank you.
 
I see. So are these temps that im seeing the ones that i should be worried about? Whati mean is, if these temps go over the recommended temp for the cpu, should i be worried, even if after i turn off the load the temps drop that quickly?

The recommended temperature for IB is 105C and below. The CPU will automatically throttle if you reach that temperature. The themal trip is 130C for an instant shutdown.

Fast temperature drop is normal as well as fast rise.

I thought it shuts down at 105C?
 
While CPUs don't really use all that much power, the power density is surprisingly high.

Some rough estimations puts things slightly under 1000 solar constants (the energy of the sun felt from earth) when stock and definitely well over that when overclocked. We all know what happens when you focus the sun with a magnifying glass into a point. The same effect happens when you try to push 150 watts through a CPU just barely over 1cm^2.
