HP Z8G4 freezes at high temperature (at 97 degrees C)

[Mr2D]

I am configuring x2 with Gold 6146 really hot temperature. I often hang, freeze. The screen still displays but the whole system does not respond I have to press the Power button to turn it off. Is this because the temperature is too high? The CPU cooling system of HP Z8 G4 is really bad or CPU Error ?

I have experience with HP from Z800, Z820, Z840 and now Z8 G4 so I can say I am an advanced user
1. Windows 10 Pro for Workstation newly installed
2. SSD I bought new Samsung 970 Plus 2TB to replace the previous WD SN740 nvme 256GB
3. Temperature monitoring with CSV log of HWiNFor64 for DTS temperature for CPU and GPU
4. I removed all Raid Card and 2nd SSD leaving only Video Card Nvidia A4000 and Samsung 970 Evo
5. Ram swapped, I only have 4 total 16GB sticks, instead of running 4, I run 2x16 to 32GB (and swapped in combination)
Result still freezing... Looking at the temperature of HWiNFor64, it is around 97 (at time system freeze)
6. BIOS latest update v02.94
7. Windows to power plan is Utimate Perfomance

And the result is still freezing as usual when the temperature is above 97 degrees with the power plan is Utimate Perfomance (What I know is that high temperature CPU will reduce clock, or suddenly power off, but mine is freezing, all fans are still spinning and can not receive any response from the computer by external devices. I only except pressing the Power key to turn off the power and restart after 15-30 seconds)

All the above factors I eliminate software, and only related to hardware.

The main problem is that I cannot identify which part is faulty to exchange for the supplier, because I buy components from many different suppliers.

The only thing I run is Android virtual machine LDPlayer about 4-5 virtual machines, the configuration I set 2CPU - 4GB ram

All my components are warranted for 12 months and I cannot know where the fault is to receive this warranty.

Thanks for the help !

Can anyone help me?
I found a similar post with the same error as me.
And it seems the HP community is avoiding answering this issue
