Zbook 15 cpu core temperature?

[UUderzo]

Hello.

I'm using a Zbook 15 i purchased some months ago mainly for heavy computing, like rendering or 3d system solving that put the cpu to the maximum power for extended time.
I recenty tried a little app called cpucore because i wanted to know the temperature my cpu works for so many hours a day an i was concerned seeing that after a few seconds of heavy computations the cpu goes to 85-90 celsius degrees, with maximum peaks of 98-100. The cooling fan works normally and it doesn't look it needs cleaning by a visual examination.
Does Zbook accept this working condition or should i be concerned?

Thank you! Umberto

I was able to pull the quickspecs for your Zbook and here is what I found:

Temperature Operating 32° to 95° F (0° to 35° C) (not writing optical)
41° to 95° F (5° to 35° C) (writing optical)
Non-operating -4° to 140° F (-20° to 60° C)

If the temperatures you are seeing are indeed listed in celsius, the system is definitely getting too hot. Make sure that you have good airflow, maybe even try running a small fan to see if that helps. Please give us a call and let us know if we can provide any further tips to keep things running at the optimal temperatures.

Hello Umberto,

The operating temperatures that Kim provided from the Zbook 15 Quick Specs are for the ambient temperatures in which the system will work, not the CPU temperuture which can get much, much, hotter without causing damage.  The same is true for the Nvidia and AMD GPUs, in case you later check the temps on those.

See page 74, Table 25 of the Intel documention, which shows a maximum Tj (Temperature at the die of 100*C).  I'm also not sure if the CPU core reading is correct, because there is a temperature offset value that needs to be included, as an adjustment of the measured value.

I worked on the electrical design for this notebook.

Thanks,
