PC freezes (and stops)

Hi,
I ordered a PC 1 year ago (Jun 2020, order #1763418) and added an NvidiaGTX1060-6G that was in my previous PC, I never had any issue with the PC until this weekend. This weekend, I followed a "well known" Youtube tutorial on how to model and render a 3D Donut in Blender. The first time I rendered my Donut, the PC froze (I couldn't move the mouse, ctrl+alt+del didn't work) so I power-cycled it. After reboot, I tried the render again. This time, after freezing for a few seconds, the pc stopped without warning. "Windows events" didn't log any crash/BSOD.

I am not a PC hardware person. Since I added a GPU that wasn't in the initial build, I first thought about the power supply; asking Google:
GPU (1060): 120Watts
CPU (i7-10700): 214Watts
So the 550W power supply seams enough.

Next, I thought about CPU temperature (PCS had to change the CPU fan during the build). Using Real Temp, the CPU temperature goes up to 100C during the render. I found the maximum temperature for this processor is 100C (https://technical.city/en/cpu/Core-i7-10700). I also used HWiNFO64 but everything is "green" or "orange" (as long as I don't see "Red", I assume I'm OK)

Wouldn't the CPU throttle instead of stopping the whole PC?
How can I be sure the culprit is the CPU? I assume PCS tested the CPU under load, it doesn't make sense that it's what is failing.
I recorded (using my phone) the video outputs of HWiNFO and RealTemp. I am happy to share if it can help (and that it's not obvious to someone knowledgeable that a pc stopping like that is due to X).


Thank you for your time.

That looks to me like the CPU cooler is failing. This is about the 4th of those PCS Frostflows that I've seen fail in about a year I tend to discourage people from getting them because of that.

I would contact PCS and see what they say
