The only option I have is to use the BIOS 'Smart Fan 5', which is less than ideal for a product sold at a premium price.
I would have to install the motherboard System Information Viewer to see Pump Temps, Fan Speeds in Windows, but I have no way of knowing what the coolant temp is.
EK seem to...

There's nothing at all in HWInfo64, and the software from EK is unreliable.
Hopefully you guys can figure this out.
Love your work as always, keep up the good work!
Update:
Loading optimized (stock) BIOS defaults then booting into Windows see's almost identical behavior with this sensor.
It sometimes dips into the high 1.3v range but mostly in the 1.4v range.
So this must be by design.
Thanks Martin!
I have 'Snapshot CPU Polling' enabled and doesn't make much difference.
I should see what this value looks like at BIOS defaults to see if maybe it's a problem with BIOS F34?
Good to know my CPU is ok for everyday use, wish there was more information about this as many are coming...
I'm seeing exactly the same thing as the OP.
New 5800x on Gigabyte Aorus Master X570 (BIOS F34)
Win 11
Latest build of HWinfo64 running
Using PBO with negative -10 all core.
Turned off 'Cool n Quiet' and C-States, and haven't even loaded XMP profile yet.
I am seeing 'CPU Core Voltage (SVI2 TFN)'...
Why are the effective clock speeds shown when my CPU OC in BIOS is fixed multiplier with every C-State turned off. No Speed-step or Speedshift either.
Fixed vCore too, so while my usage of the cores may fluctuate, the core clock speeds do not.
Windows using Ultimate performance mode with min CPU...
Ignore me.....I'm having a brain fart from lack of sleep.
I somehow got onto the idea that because all my intel builds have XMP DDR4 that is always 2T then that applied to all DDR4.
Using compatible Corsair Vengeance XMP 16GB (2x8GB) 3000mhz kit - checked the Asus site.
Asus B450M Plus Gaming - the board came with BIOS 0809 which is from March this year I believe.
Ryzen 2600X
Sticks in A2 and B2 as per manual
Enabled DOCP (XMP) in BIOS 'AI Tweaker' - reports correct...
Thank you for the follow up Martin!
So, the VR VOUT reading is correct:
1.378v at Idle
1.355v under load
I should trust these settings more than the reported vCore of 1.392 (1.395v fixed in BIOS)?
So if I want to keep my actual core voltage under 1.40v, then I can raise the BIOS...
Thanks Martin!
Hopefully AsRock will confirm with some data from a calibrated oscilloscope.
Thoughts on that inexpensive oscilloscope?
Would it give a reading that would be useful?
Martin,
Would this oscilloscope work for measuring VR VOUT?
I don't want or need a several hundred dollar lab unit, this one seems to get good reviews.
I'm attaching stats

Thanks.
I'm emailing AsRock who said they will open a work order and test with oscilloscope.
I also posted in Reddit to see if 'Elmor' might know something about this.
So you think Ada64 Extreme would show different settings than HWinfo and perhaps coded with these controllers in mind...
Ok, so just use BIOS vCore and then assume that under load the VR OUT should be less than the vCore given all the detailed explanations on why fixed vCore with aggressive LLC will always be higher idle voltages than under load due to vdroop by 0.01 - 0.02mv it seems in my case even if just...
Not sure I understand your feedback?
In bios I set fixed voltage to 1.395 and LLC1 (most aggressive on this board).
Under full load the vCore I'm HWinfo and cpu-z shows the same value of 1.392v.
The VR OUT value when under full load shows 1.368v and idle 1.42v.
Not sure if that helps?
I am trying to understand which entry to trust since the VR OUT (true core voltage instead of vCore) and VR loop 1 (VRM temps) are different.
I've attached an image which I hope helps.
All BIOS settings are stock EUFI defaults - no overclock applied so I can show baseline values.
Board is AsRock...
