There is hysteresis for the fans; it's limited to 3 degrees. Usually works but there are some people with Noctua fans especially reporting these spikes.
I think you can manually modify the curve in the BIOS (not 100% sure); I'm pretty happy with the Normal for the CPU and Silent for the rest. I change too often profile to mess with the fans setup.

The temps seems right to me; my 3800x is idling browsing at 40-45 right now. Full max load with AVX is 78 degrees.

I use Process Lasso; it switches between the Ryzen Balanced (which I modified from default with Min CPU usage at 0% and No PCI-e Link State PM) for normal usage to the Ultimate Power plan for games and specific applications.
do you think its the noctua fans causing this ? does any otehr person have this problem with different fans.

also what power settings are you usign in windows 10 amd ballanced or high performance.

cheers

The GB Z390 boards had some bug where DVID mode changing was not working correctly in some situations (especially when changing from fixed to offset, etc) unless you rebooted twice, or changing from offset to fixed would cause overvoltage or the offset applied on top of the fixed, or the fixed profile loadline calibration applied while still in offset mode, until you rebooted a 2nd time (not sure exactly which). These bugs existed since release and were only fixed in the very latest beta bios, after I was fortunate enough to contact an engineer and they were able to reproduce it, I tested it and the latest Master bios fixed it (still not available on the official pages, only on the tweaktown beta bios forum).

A bug where changing from the "default" fixed voltage (1.20v) to auto or DVID still doesn't work at all. Only happens if vcore is set to the "default" as a fixed override value (1.20v). Doesn't happen at any other fixed value (e.g. 1.205v, 1.195v, etc)

May be partially related to your issue. Try to avoid setting a fixed voltage to what the BIOS says is the 'default' and then changing voltage modes from that value. I don't know AMD hardware so I'm probably way out in space here. Sorry.
I believe this went away after a couple BIOS upgrades, it happened with earlier BIOS versions.
I tried to undervolt a little, saw it wasn't working, and happened to run into 2 guys discussing the same issue on some other forum (sorry, can't remember the name).
In the end I managed Default/Offset: -0.062 (instead of the BIOS default of "Auto").
After I applied the suggestion to reboot twice, I could finally see the values I was expecting in HW and Ryzen Master, and was able to finally test the changes properly.

I see battery drain since July, I thought it happened when you were testing the stock cooler, my bad.

Yeah, the pad situation didn't sit right with me either...

I posted an image awhile back from replacing the thermal pad on the chipset. It shows some liquid crap that oozed out of the thermal pads used under the vrms and back-plate. If it were conductive my board would have fried long ago but I'm wondering if that could cause some type short or other issues if it pooled over the battery contacts.

Yeah suppose so, they are Chinese batteries after all lol

I was testing the problem while the pc was off and testing how much power it needs to start working, the fan works as expected. I highly doubt the fan draws enough current even at 100% to cause instability on cold boots. I don't know about others but my pc has 11 fans to start, no RGB and it starts just fine. For the fan to drain the cmos battery is impossible. I can't detect any issues with this board and think it's a cracking MB.
Ok got it; I also had random bios resets due to soc/vddp/vddg settings.
Steep learning curve for me too coming from an i4770k...

But the issue about the cold boot issue they reported is different.
From what I understood it only comes up when the PC has been off for some time.
This should exclude any kind of peak load at boot.

Fingers crossed, for me too so far so good.
On the hardware side, I'm just really disappointed about the thermal pad on the SOC, complete rubbish.
And seems also the pads on the back plate are going to be an issue.
But the VRM part is really top notch and in the same price range I don't think there's anything that can come even close.

A dead battery is sadly pretty common nowadays, more than years ago. Main reason is the proliferation of cheap couriers and poor quality of the batteries.
Often the goods are left weeks freezing at below zero; if your container is unlucky and exposed to the sun on the ship, the whole trip it's a continuous thermal shock from zero to 60 degrees.
These coin batteries are really durable but an excessive temperature can drain them very quickly, especially if the manufacturing quality is so-so.

I guess you misunderstood his issue characterization
He didn't have the LEDs on with the PC switched off, that would be voodoo magic indeed!
Simply the LEDs were set to on by default; he connected the USB cable just to switch them permanently off.
My guess the LEDs are switched off by a tiny permanent electromagnet relay, effectively disconnecting the whole LED control circuit.
Maybe some boards have a grounding issue involving the 3rd or 4th pin of the fan connector? I really don't know.

I'll have nightmares tonight
Every time I see those pictures my stomach starts aching.
I should have replaced those thermal pads but they weren't melted when I removed the back plate.
At least at the time, not sure about now...

Yeah it's unlikely that awful liquid is even minimally conductive. You board would be fried like french chips.
Also there are probably much more delicate signals around there, it'd have caused a mayhem of issues long before draining the battery.
I'm more inclined to think it's some weird design flaw in grounding.

At 20% all the LEDs are disabled with the fan trying to spin, but not fully as there isn't enough volts. So if any power was going to the fan to enable the LED controller then surely the fan would be moving? The fan moves before LEDs switch on. The USB and RGB cables are just for software control. Why isn't the RGB cable connected to the motherboard RGB so you can sync the colours? Stupid

I have noticed a slight battery drain on my board 3.216v. I can't see how this can cause cold boot issues(likely an unstable setting), because if the battery was insufficient then you would just lose your bios settings. And anyway the cmos battery can drop to about 2 volts I think before you lose your settings. If you are like me and never unplug your PC from the mains supply, you'll unlikely ever need to replace it, bit like the backup battery in your alarm clock.

The fan unless it has a different power source for the LEDs has one 12v line for the fan and LEDS. Fan starts spinning at 20% 2.4v approx and LEDs turn on at 30% 3.6v approx. PC on or off, the fan has one source of power, the fan and LEDs run on this same source of power and are not independent when just using the fan header. How this guy had LEDs on without the fan spinning while his pc is off, haven't got a clue, voodoo magic.

To get a dead battery on a recent board is a bit much, I would expect this to happen if the board that was at least a couple of years old, then these would have to kept in -XX'C conditions to deteriorate the battery excessively. I don't think I've ever had to change a battery on mine, even on Intel EX58 motherboard that lasted me 10 years survived on it's original battery (RIP motherboard did me well)

I think we can assume this is not battery related, because the motherboard doesn't care about the battery.

It could be connected or just a side effect.
He didn't connect the RGB cable because he wasn't interested in having the LEDs on.
You are looking at the behavior of the fan and the LEDs while it's on but the issue is showing up while the system is off.

Whatever it is, and we don't even know if his case is similar to the others, I think it as something to do with a design flaw.
Most of the reports came from users using almost a default profile, I don't think it's related to it.
The ErP setting is one of the few that should be considered IMHO.

The loss of settings should happen if the battery voltage drops below 2,7V.
Also there, almost all users with this issue had a battery with full capacity.
Those with a drained battery usually were able to solve it with a new one.

And a drained battery from start it's pretty common, usually means the board was improperly stored in a warehouse too cold.
