12700k idle temps in bios and windows

[ekwong7154802dc]

I just bought a 12700k chip and installed it on a MSI z690 Pro wifi DDR4 board with a NH-D15 Noctua cooler. My idle CPU temp in bios is 27 degrees C and CPU socket is 28 degrees C. It is normal for the CPU core temp in MSI center to jump to 39 to 45 degrees when idle in windows? I run the stress test on CPU-Z and I get to 65-66 degrees C.

Why is idle temps in bios so much cooler than in windows with the 12700K? Is anyone getting the same jump in idle temps in bios and windows? I do have Adobe creative cloud loaded on the computer...that seems to draw alot of CPU usage in the background. Could that be making my temps jump at windows startup?

I found a fix on youtube for my 100% CPU usage in windows issue on youtube if anyone has the same issue. Search youtube for "Mikethetech" and his video how to fix 100% CPU utilization bug. It worked for me and my idle temps are now below 30 degrees C.

Windows always runs some background task. Rest assured, your temps are fine. Mine are quite worse (NH-U12A).

The temps are only the symptom. Higher CPU load causes higher power draw causes more heat. So you have to look what's causing the higher CPU load.

Now, you said you solved it, so i assume you removed something from autorun that was causing high CPU load? Care to post what you did?

Certainly not, he has a Noctua NH-D15, like me. During idle, any recent Intel CPU should draw around 10W or so, 15W at the most. My CPU temperature is 28°C with that in Windows.

With an NH-U12A it might be higher, but not above 45°C. So if you have even higher idle temps than 45°C, check if the heatpaste was properly applied, or if your airflow through the case is good.

There is a bug in win 11 where a service will go stupid running when it should not be using about 5% to 10% of CPU

Check in Task manage to make sure they not running non stop or using to much CPU if running as it is designed to it should use less than 0.5% of CPU at most.

Mh, at stock (which on that board means unlimited power limits) I got similar temps at idle (<30C) but ~80/82C on full load (prime95). At 150W/150W I get 68C full load.

Yeah, if you were talking about temps under load, then ok. But he was talking about strangely elevated idle temps.

Yep, I wanted to highlight that if he was getting good temps under load, then his heatsink made proper contact, and the cause of a high idle temp/power draw was to be investigated elsewhere (e.g. OS background tasks: note that this varies according to system config and installed apps).

Look up "Mike the tech" on youtube and how to fix 100% CPU utilization bug.

Went into CMD and typed the following and it fixed it.

PowerCfg /SETACVALUEINDEX SCHEME_CURRENT SUB_PROCESSOR IDLEDISABLE 000
PowerCfg /SETACTIVE SCHEME_CURRENT

Ok, that influences the current Windows power plan. Can you click the start menu and enter power plan to see this:

This should always be on "Balanced". Sometimes, installing certain crappy tools like - *ehum* - MSI Center, will needlessy set the power plan to High Performance. Or it might even mess with the Balanced settings, i'm not quite sure, and i don't want to install MSI Center to check. So then you would have to set it back to Balanced and it would run cooler again. I think those two commands from above just try to make the High Performance power plan act more like the Balanced one again. But i would like to know what plan is selected for you.

It's currently showing "Ultimate Performance" ... might be a new choice in my Windows 11. Is that Power option screen shot from Windows 10 ? I don't see "Ultimate Performance".

That is strange that my new 12700k build shows the "ultimate performance" which isn't shown in your screen shot or in my older pc a 9700k. My new 12700k build was a fresh install of windows 11. My old PC had windows 10 which I updated to windows 11 and doesn't show "ultimate performance".

Aha, yeah, this Ultimate Performance will have been the culprit. It sets the Minimum processor state to 100%, meaning, even when there is no CPU load from any program, the CPU will always clock at the highest frequency. Obviously, this isn't very efficient, for home users it makes no sense at all. You want all the power-saving mechanisms fully active, so the CPU draws the least power when there's nothing to do. When there is CPU load, it will wake up within nanoseconds anyway, so this "Ultimate Performance" (and even "High Performance") power plan makes even less sense.

What i assume that your command lines have achieved is to activate some power-saving in idle again for this power plan. Setting it to Balanced should achieve the same.
It's entirely possible that MSI Center did this. Especially if you use some feature in there that you're not 100% sure of what it does. For example, don't try the settings to supposedly improve performance, it may try to overclock your CPU, and that is not advised. Especially not automatic OC, but also not manually.

Thanks. I might have clicked on something to boost performance in MSI center or download something from MSI center. Now I wonder if it over clocked my CPU. MSI center should explain what the boost performance does to the system.

Power plan would be set automatically when different User Scenerio being set in MSI Center as screenshot shows.
With Extreme Performance Mode selected, Windows Power Plan would be set to Ultimate Performance:

 

[citay]

Yeah, i wonder i how many people click on "Extreme Performance", not having the slightest idea that it will cause much higher than necessary power draw without actually doing much for performance.
That's one of the reasons why i usually advise against installing MSI Center.
