To check if my cooling system has something wrong like some people claiming or better say suspecting. The question is what will be differences between processor and room temperatures

As a simpler approach

Use SIV, it s free, without gimmicks and includes some bench but does a good job reporting/managing
The fellow behind, Ray, it is very impressive on his skill set and knowledge


My suggested approach

compare my included screenshot to your system at IDLE. Start off with what temps shoe extreme or have a high deviation so that you can see an outlier before its run at a stress point.

Some caveats,
let the system run idle for at least ten minutes
and have the room at 69F-71F

compare and see what had a significant mean deviation to this in looking for a hot spot:

I thought you are using Silverstone liquid cooler like I use. Then my request to check the temperature has no point.

As to using Windows tools, the problem is that both my MZ73 and both generation processors do not like to boot from even legit Windows installation flash. Probably because these boards need server Windows version and I don't like to pay Bill Gates for that a cent. How did you install your Windows?

Dirty way with not predictable result which i used before was to install Windows on another computer and take the disk to Mz73. It disintegrated eventially

Sir
This whole build was based on air cooling, a quiet cool running all air cooled build.

as for a window install, I installed windows server data center from a iso on a usb drive

Afterwards, once it works fine, I keep a gold backup as a starting point and restore the gold back up for builds

I use Macrium for back up and restore

I’m glad to help, but you sound like you have a lot of other issues going on beyond a bios configuration

With all due respect, where/why would you assume I had the same liquid cooler (any) as you ??


This (my) whole build was based on air cooling, a quiet cool running all air cooled build.

Afterwards, once it works fine and all is well, I keep a gold backup as a starting point and restore the gold back up for builds.

I’m glad to help, as have other members of the community here, but you sound like you have a lot of other issues going on, bios configuration, CPUs, how to wipe a cpu clean, how to do a windows install, power supply, cable connections, hot spots and liquid coolers…

I’m not sure I’m the expert you need

With my update/upgrade I had some left over parts, so I made for her a new rig, a home for my former 4090s

So for my wife ~ I built her a "Min-ime" (Dr.Evil's clone) of my rig:


Mini-Me, the specs are more humble:

Machinist x99 D8, bios .004, with ReBar (yes, a Chinese motherboard of Amazon for $159. I did my research before I bought it and a backup board)
and modified VRM heatsinks
Dual Sabrent TLC, 8GB each nvme’s (OS & D drive)
4x Samsung 860Pro, 4TB each (16TB storage pool)
Dual Xeon E5-2699A V4, 44 cores/88 threads
512GB ram ECC, 2933mhz (running at 2400mhz)
Dual 4090 FE GPUs
Hela 2050R PSU, 2050w
MS Server Data Center 2022 & 2025
Asus PA32UCG-K monitor
SoundSticks III
Keychron pro q max keyboard and mouse
and of course a Lady Deadpool user avatar (she is a Deadpool fan)

Case was a Thermaltake Core P3, same as the one I use / modified, I made protection bars instead of the glass, modified for wiring, support, motherboard and the standard outrigger PSU


Her whole PC is quite silent even under a respectable load, she does rendering, video edits and she’s also a gamer

While it has been said before:
Happy wife, happy life

Its a nice size room, but even with hard floors, the sound of the PCs (considering the hardware) is quite minimal, borderline inaudible when PCs are idle and only a mild fan noise under load. Fan curves were tweaked to accommodate performance but also be silent at the right times.

I had to make a bracket system to keep GPUs from sagging

There are two more PCs/desks in the alcove area for my kids


Yes, I'm guilty of always using the same case as a baseline but I've been doing that for a while, doing back 13 years:

This was made using Titan Vs when they first came out

So the current build of my PC is really just been part of a continual design refinement on air cooling:

So a small update. Have looked for companies that build workstations and saw they also use Seasonic 2200W PX-2200. So now the ovecr current protection LED on the motherboard doesn't start blinking, but everything is the same - fans spin up for a few seconds and BMC isn't accessible afterwards (need to disconnect power to get access to it again).
