Update:
Windows wouldn't even boot anymore due to a CRITICAL_PROCESS_DIED BSOD on boot.
Really seems like whatever the problem has been, it has been corrupting data!
So I removed the four screws from the block on the CPU, then lifted it off.
Then four springs fell onto the motherboard as I was lifting it.
Then it hit me instantly.
Some MORON had put these springs on the WRONG SIDE!
They were supposed to be directly under the screws!
On THAT side it would interfere with contact between cooling plate and the CPU!
So I fixed that and redid the thermal paste.
Thanks to you and all the rest of you who mentioned to check this!
I was pretty sure I'd be home free after this fix.
Not exactly.
I reinstalled Win11 on the 4TB SSD.
Within 10 minutes or so it rebooted on me. Nooooo!!!
Event viewer showed this again:
A fatal hardware error has occurred.
Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 30
I then installed the AMD chipset drivers, and then did "Load Optimized Defaults" in the BIOS (which is resetting it, I THINK)
(I had done those things previously to no avail).
And THEN....
I had over 6 hours of uptime!
During that time I ran AIDA64 system stability test for an hour, temp peaked at 64c
Then I ran Prime95 torture test (blended) for an hour and fifteen minutes, temp peaked at 80c for a few seconds multiple times.
As I was writing this post, with a smile on my face it FROZE AGAIN. Then I rebooted and it froze again while I was trying to finish this post.
Torture testing and system stability tests were passed, but it freezes on this webpage while I'm writing this?
That's the update.
This is how have I have my AIO setup. Had to put it this way so the 4 DIMMS could fit (not all present at the moment)
That is suspect. At idle, my (slightly older) 3950X is below 40° C, and when playing CPU intensive games, it is not pushing much above 60° C. If you're doing 'basic' things and it climbs to 73° C, then I suspect that your heatsink is not making proper contact.
How is the radiator mounted in your system, and have you watched the GN and / or Jayz Two Cents video on proper mounting? Since you changed the orientation of the cooler on the CPU that might be causing an issue.
Also, double check to see if that model is not known to have issues with problematic gunk inside the pump and cooling fins, I know there were some AIOs that had an issue like that, that you may not have experienced before simply because the (previous) orientation overcame the buildup, but now changing it around *is* causing issues.
This thread has links to both GN and JTC vides regarding orientation:
Hi all, after a lot of debate, I ordered the EK AIO 360MM rgb: https://www.amazon.com/gp/product/B0842YK4L5/ref=ppx_yo_dt_b_asin_title_o01_s00?ie=UTF8&psc=1 To cool my 10850K which can do 5.0 all core and possibly more. When I asked about air vs CLC vs AIO, people mentioned having proper...
