What AIO liquid cpu cooler(s) are you using for your 3950x/5950x system(s)?
I have advice on the low price leader. What about the one that keeps it coolest and is most reliable?

The +12V Voltage should be much closer to 12V, not at all +10.08V. That may be why you are resetting, or shutting down. And the running temp of +87.0°C is getting near the temp of automatic throttling.
.....[EDIT].....
What is your PSU that you're using on this particular MB w/3950X?
Have you swapped out ANY cables from this PSU and another PSU? You should always keep the cables with the exact same PSU.
If for some reasons you have the wrong PSU cable causing a substantial voltage drop, or "droop", that could be your problem, or at least part of your problem.
George I fully agree with you about that 12V reading. Tom should look into that. If it’s real I’m surprised the system is even able to stay running at 10v. I’ve seen issues caused by 12v drooping down to even 11.4v let alone 10v.
Tom, do you see this low of voltage when the system is at idle? (BOINC not running at all).
if this value is real, it could be the source of many of your ongoing issues, not just with the CPU processing but also with your constant GPU issues. A new PSU might be in order.
while the temp is high, and it might be good to bring it down, it’s not dangerous. I think Tom is already planning to get some kind of AIO to bring the temps down.
Tom, needs to look at the Monitor page and the +12V reading in the BIOS and verify that it is correct there first.
Then look at the +12V reading via sensors at idle.
The asus-wmi-sensors driver that is polling the motherboard SIO chipset is stable and all of the known bugs have been worked out. It should be showing the actual sensor reading.
In fact the driver is mainlined into hwmon in the 5.17 kernel.
He also should verify with a multimeter what his 12V rails are measuring under load by plugging in a Molex cable to his power supply and use its female connector to probe with the multimeter probes. They fit perfectly. This is the easiest way to access the voltage. You can also probe the wires in the 24 pin connector on the motherboard but that means you have to probe the backside of the socket and shove the probe tip past the wire insulation to contact the metal socket pin and is more difficult unless you have fine needle tips on your meter probes.
Black probe to black wire. Red probe to yellow wire. Outer wires are +5 and +12V. Inner wires are grounds.
I agree that this voltage if verified with a meter is the cause of all his issues.
What AIO liquid cpu cooler(s) are you using for your 3950x/5950x system(s)?
I have advice on the low price leader. What about the one that keeps it coolest and is most reliable?

I don't use any AIO coolers anymore on my active hosts. All are on custom loops.
I think I have one on a closet contest machine still.
The rest are sitting in the closet gathering dust. 7 at last count. Mostly H110's, a couple of old H105's, a H100v2 and a CLC280.
General advice is fit the largest radiator your case will allow. Plenty of 360mm AIO kits out there now. Some even with full coverage Threadripper coldplates.
I have an EVGA CLC-240 on my test bench. But only for convenience. All of my BOINC crunchers have the CPUs (all are EPYC Rome/Milan at 200-240W) on custom watercooling with at least 360mm radiator per CPU.

Personally, I am using a 360MM EKWB radiator and a simple water pump (I bought from Keith), not a D5 or DDC pump, on my 5950X with Arctic 120mm fans (I bought two 5-pack fan kits from Amazon). My 5950X is running at 4.425 GHz & ~145 W Package Power at roughly 60॰C. So I think your pursuit of a higher grade or capacity cooling solution should be after your hunting down the cause of the voltage drops first.
Another thing is your motherboard has only one 8-pin EPS connector for the CPU, not two, or one 8-pin & one 4-pin. This may limit your voltage to your CPU and POSSIBLY be another reason for the voltage to drop to 10 volts while overclocking.
You haven't said whether you MB is a 'gaming' board, or whether it is a 'I' or a 'II', but regardless, they are the same as far as the connector goes.
The 8 pin EATX aux cpu power connector along with the 24 pin provides plenty of power for a cpu.
However, depending on how many gpus he has plugged into the mobo could load the 12V power rail down significantly.
That is why server or workstation boards that have 5-7 PCIE slots intended for add-in cards often provide a dedicated PCIE 6 pin auxiliary power input connector JUST to provide 12V power to the PCIE slots.
It also commonly uses a independent 12V power plane not common to the cpu 12V power plane. So neither cpu load or the gpu or PCIE loads interfere with each other.
George, the XSPC pump I sold you is a D5 variant. Essentially equivalent to the old D5 Vario series with the pump speed selector set on position 4.
Still, a heckuva lot better pump with better flowrate than what you can get in any Asetek derived hardware AIO kit.
And good enough to cool both my twin GTX 1080 Ti's and a 5950X in my latest upgrade.
I was not aware of the pump that you sold me was a variant of a D5. Thanks for the input.
But I agree that it is a much better pump than any Asetek AIO.
Like I said, it is doing just fine with my 5950X and Tom's 3080 overclocked +100 & +1500.
I can barely wait until I get my new Meshify 2 XL case and water cooling 'stuff'. My intent is to put the setup I have now into the new case, and also the two 2070S's (all 3 GPUs water cooled & CPU too) put in there.
