So basically im seeing the cpu temp jump around 45c to as high as 70c. Its like its doing something in the background but im not sure what that would be.
I checked the core usage and the last two cores (22 and 23) seem to be the ones spiking the most consistently. Most dont spike at all.
The thing is i did a complete reset of my pc recently and it is after this reset that im having this "issue". Before i did the reset my cpu temp was a lot more stable. Before the reset my temp would only spike when downloading and installing stuff. Now its like its constantly installing stuff.
Does resetting your pc delete all drivers? Perhaps im missing some driver that i had before the reset?

I did a bios update like two months ago so its not that. Also bios isnt affected by pc reset right? If my bios version was F11 before reset it should still be F11 now after reset?
What about chipset driver?

I have the Gigabyte Aorus x570 Master.
Yeah i need to explore the settings a bit i havent really done that ever.

What i did just now is i disabled Precision Boost and Core Perfomance Boost just to see what that does and i feel like things are a tad bit more stable, the fan isnt having a heartattack like it was before however now the cpu is running at 3.6 - 3.7 GHz whereas before it was running at pretty much a constant 4 GHz boosting beyond that ocassionally.
This is a lot more pleasant for my ears, the fan stresses me out more...

Does it just spike and then immediately go back down? If so, no need to worry. All CPUs do this to one extent or another. It's just more pronounced in the Ryzen 3xxx series.

Yes it spikes and goes gown and then spikes again a couple seconds later. It never stabilizes.
I have heard that its "normal" but what doesnt make sense to me is why it was so much different before i reset the pc. It was around 50c pretty much all the time ONLY jumping around when performing updates and downloading games. It was even stable during gameplay.
 
What CPU cooler do you have?

Might as well list all your specs, including power supply.

When you say reset, do you just mean the operating system? Are you using the exact same program (and program version) to monitor your temps as you were using before?

Im using the wraith prism that comes with the cpu. I was using it before the reset as well.

Gigabyte Aorus x570 Master
Ryzen 9 3900x
Sapphire nitro+ rx 5700 xt oc
2x8gb 3600mhz
Corsair RM750x

I mean i did shift restart -> reset pc. Im using the same programs to monitor yes, hwmonitor when idle and browsing and afterburner during gaming.
Thing is i have the case open so i can hear that its behaving differently because the fan is going up and down in speed constantly as the temp jumps around.

It revs up as soon as i open something like the tiniest program, im not sure why it has to work so hard to deal with one program. Even when browsing if i click on something it revs up.

This sounds like something got jostled.
Maybe try reseating the heatsink and fan using good TCG.

Im sorry im not with the pc lingo. What does jostled mean? Also what is TCG? I googled it and got pokemon lol.
I think im getting you though, you are telling me to perhaps remove the cooler and re- seat everything? Maybe even reapply thermal paste im thinking?

I would try updating all the drivers on your computer as a first option... also if your computer is trying to update everything after the reset it maybe overloading the CPU if you are using it while it is trying to update the software, but if you were having slight over heating before the reset you could also check the fan is clean and not to much dust in your computer as well. Or troubleshoot over heating/cooling options for your PC from the manufacturer.

There are no updates running though and its been like this for two days now. Even if it was updating things in the backgroung then surely it would be done by now.
I didnt have overheating before, like i said it was very stable. The fan is fine i can see it right now everything is clean.
 
try to put the power plan in control panel to balanced, it will lower voltages when idle. IF your temp stops jumping you have identified the problem.

It's running Windows in the background, that's what it's doing. If you look in Task Manager you'll probably find upwards of a 100 open processes. The vast majority are idle but many occasionally do something. When one does it's normal for clock speed to spike up from idle to get it done fast and return to idle. Ryzen works different from what you may have seen before, that is perfectly normal when set up properly.

Along with the clock speed spike it's also normal to see a low energy temp spike accompany it. Instead of looking at the temp spikes, which are very low energy and don't heat the processor up much (think of a match in a room...the match is hot but the room isn't) look instead for an average temperature. Ryzenmaster reports an average temperature and so does HWInfo64. The average is a better reading of the true temperature state of the processor.

It also favors certain cores to spike clocks, that's why you see those two sharing in the fun.

The reason resetting your CMOS returned it to doing that is because it removed any settings you made that broke your PC. Congratulations!

I really want to believe you dude but idk... It was just so much more pleasant before when it was stable and i didnt have to listen to the fan go up and down constantly. I know that i can probably adjust the fan curve so that i dont hear it but then my temp is going to be high and i probably dont want that...

This might not be relevant but i will mention it. Before the reset my motherboard was showing code "AO", that was when the cpu was stable. After the reset my motherboard is showing "AA".
The manual for this motherboard is atrocious, it just says "reserved" for code "AA" so that doesnt really tell me anything. code "AO" says "IDE initialization is started", i have no idea what that means...
I have googled both codes and its confusing because some people say that it should show "AA" when everything is working properly but then some people say it might be a cause for concern.

HWmonitor is probably your problem programs like it wake up ryzen cores and that causes the temp spike that isnt really accurate i recommend ryzen master and hwinfo64. And few cores boosting sounds just about right for windows background stuff.

Not really, if i turn HWMonitor off its still the same. I installed ryzen master and its showing 44-45c when im not touching anything however as soon as i move my mouse it jump to 48c. Not opening anything just literally moving my mouse around makes it work... is that normal? Like... does yours do that?

Yup sounds normal, ive got r5 3600 idles around 41c-46c and the second i move mouse etc it goes up by 2c-4c and thats the beaty of ryzen the clocks boosts on "Bursty loads" such as opening a program or navigating around the OS etc.

Yep, sounds normal. It's trying to sleep as many cores as it can but when you move the mouse it's waking one or more cores, more often, to deal with it.

Although it seems a bit high...are you using the stock Wraith? My 3700x will be 32-33C just sitting, start moving the mouse it goes up to 34-35C. But I'm also using a 240mm AIO.

Yup im using the stock Wraith Prism that comes with i think all the ryzen 3000 series cpus. I do have a 360mm AIO but right now im not using it as im waiting for a new case to arrive because the one i have makes things way to tight and actually the aio ends up scraping againts the top of the motherboard.
Those temps you have are amazing man... i hope i can achieve something similar when my new case arrives. I will have 360mm AIO + 7 case fans in there.
