Can exceeding a Core I GPU thermal junction temperature cause the CPU to throttle?

Basically, the title says it all. First, let me preface this by saying that I have no idea about any of this. I'm just curious. The issue has come up while looking at an I3-350M that appears to throttle far below its max temp. In researching the I3-350M it became apparent that there is a specification for a thermal junction temperature that is at the precise level that the I3 seems to throttle under the burn test.

It looks like, in addition to the max CPU temps, at least the I3-350M processor may also have a thermal junction temperature (TJT) assocaited with the GPU that is a different setting than the CPU max temp. According to what I have read, the purpose of calculating the TJT seems to be in aid of the designing the heat sink needed to service the integrated GPU.

The question is as stated in the title "Can exceeding the thermal junction temperature cause the CPU to throttle?" If that is so, how does the chip know that the TJT has been exceeded? Is there a sensor in the GPU?

Does anyone know the answer to this question?

I believe it's called Bi-directional PROCHOT. It collects information about temperature and sometimes control the clock speed of cpu or gpu. It can be disabled or enabled using throttlestop.

 

You are the man! Now I have to read the throttlestop thread. I'm never going to get any work done.

and deliberately bypassing internal overheat safeguards will likely cook your cpu no matter how much additional cooling you add.

be careful out there.

 

The issue is not the CPU. The CPU seems to throttle 15C lower than its max temps. It is the integrated GPU temp control that seems to be the problem. But, I hear ya.

may be moot anyway. I am told by others that throttle stop does not work with Core I processors ... is that correct?

You can not undervolt core I processors,that is what I know.It might be not compatible,but you dont lose anything if you try and see
