My cpu temperature jump on idle

[khjhpopasa]

When I turn on my new pc and do nothing (idle) my cpu temperature is 38 but every 30 second +\- it jump to 48 I have any problem with my cpu or pc?
my cpu is 7600x
motherboard b650 aorus elite ax
cpu fan pa 120 se.

I have any problem with my pc or cpu temperature jump to everyone?

I saw my cpu all the time 0% usage and every 30+\- he go up to 10 for two second and that time cpu temperature jump as I described above.

and another quastion the temperature on load 10% and idle 48 \ 38 in match, its fine?

That's fine with Ryzen.
Do you live in Australia btw?

 

[jesdals]

Windows will do that and its the same on the 5950x and saw it as well on the 3800x

 

[Frick]

A modern computer connected to the internet does all sorts of things all the time and is thus never truly "idle". Modern CPUs also adjust the clocks and power many times per second (depending on what is going on there and then), and the temperature will never stay the same for long.

i HAD the same problem what fixed it for me was arctic 280mm aio with mx-6 thermal paste and alternate am4 mount temp no longer bounces. what is your cooling solution?

 

[69er miner]

are you disconected from the internet when it occurs?

Open task manager > processes and sort by CPU usage.

Stupid stuff like background antivirus, windows update, and system tray utilities can be active enough that they spin one of the cores up to 4+ GHz briefly. That's enough to generate a sudden 10C blip.

My Ryzen chips have done this for the whole time I've owned them. I saw it first with my 5600X and I still see it with my 5800X3D, based on how many people have similar experiences, I'd say this is expected behavior. It's probably throwing a decent bit of power at the cores to finish some background task quickly and then ramps back down when the task has been completed.

i HAD the same problem

48°C at idle is NOT a "problem". It is not even a symptom of anything wrong. If it was spiking well in to the 70s, 80s or higher, that would be a problem. But 48°C is just warm.

@khjhpopasa - What happens if you start your computer and use it for a few hours, then sit back and sip on your coffee for a bit?

Note when we first turn on (or wake) our computers, all sorts of things start happening in the background - that is, where we don't see. And that's a good thing! Windows may check for and install updates. Our security programs check for updates then run scans. Programs we have starting with Windows may check for and install updates. Windows does other "housekeeping" chores like running Indexing, defragging hard drives, and more.

How much happens and the time it takes depends on several factors, including how long our computer was off (or asleep) before booting it up again. I note you also said this computer is new. Depending on how long the computer sat on the shelf after leaving the factory (or when the OS was installed) may be a factor in how much housekeeping and updating may be needed to catch up to today. When all those tasks are complete, idle temps should settle down and remain fairly consistent most of the time. They will jump up again as your security program, for example, checks for new updates runs some scans. And that's okay.

I agree to check Task Manager > Startup and see what is starting with Windows. If something is listed you don't need starting with Windows, you can right-click on that item then select Disable. HOWEVER, if you are not 100% sure you don't need it, LEAVE IT ALONE!

If it is a program you downloaded and installed (other than a security program), and you don't need or want it to start with Windows, go to that program's control panel and look through the options/preferences menus, then deselect the option to start with Windows.

Sadly, many programs - even great, useful programs - will install auto-updater applets to keep them current. That may be fine if it is a program we use every day. But, just to illustrate, CCleaner is a great and useful program IMO. But it is a program I might use 2 or 3 times a month. I don't need it to install an auto-updater that starts with Windows, then checks multiple times a day for a new update. So I make sure that feature is disabled, and I manually tell CCleaner to check for updates when I run it.

Stupid stuff like background antivirus

Ummm, "stupid stuff"? Background antivirus is stupid? ???

Would you rather the security software not run? Or, every time we boot or wake our computers, the security software comes to the foreground, takes top priority over all other tasks, dominates all system resources and prevents us from doing anything until done?

Nothing "stupid" about it. If not watchful, we many end up with a lot of "stuff" that starts with Windows we don't need running in the background all the time. Some may consider that "stupid". But antivirus software running in the background is not one of them.

fans for up in two sec and make unfunny sound its isn't stable

If you can honestly tell me you've never seen Microsoft Antimalware Executable using CPU/power when it's not scanning anything, and never once had to troubleshoot it misbehaving, then fair enough.

For the rest of us, it's not the most well-behaved piece of software, and frequently causes issues with Windows update as the two teams at Microsoft clearly don't talk to each other enough or test things properly. The number of internet threads asking for help fixing high CPU usage with Windows Defender/Antimalware is almost as many as there are threads asking why Windows Update has high CPU usage even though there are no updates to install and the PC is completely up to date.

It's just shit software that frequently doesn't work as intended; If it did work as intended I wouldn't be calling it stupid.

In your BIOS, go to your fan control page and look for "temperature interval" or similar, to stop the cooling fans from ramping up and down so frequently. Many boards default to 1-second polling, and I always set it to the longest number available, typically 3 seconds. That way, unless the temperature spike lasts 3 seconds or more, it doesn't bother adjusting the fans.

Another thing to do is make custom fan curves that are more gentle, even straight lines - if idle for you is 38C, then change it to a straight line between 30% fan speed at 40C, and 100% fan speed at 95C. It'll probably be a bit louder at low load, but you shouldn't get such dramatic changes in fan speeds.

This!

OP: There is nothing wrong with your PC. It's normal Windows behavior, you would see it with any other CPU as well. Also, some background tasks don't kick in until the system is truly idle.

 

[eidairaman1]

If it were unstable your pc would bsod/freeze/crash.

If you really want to test this start with a virgin OS with just the motherboard and GPU drivers and not on the internet at all.

Ummm, you need to describe this better.

It is important to note that a CPU can go from cool to overheated in just a few clock cycles. And CPUs typically have ~3 billion clock cycles every second. Since fans are mechanical and take time to ramp up, it is not uncommon for them to quickly speed up and even overshoot what's needed - just to be safe - then settle back down.

Again, 48°C is nothing to be alarmed about.

What do you mean by "unfunny sound"? A fan that is spinning at a high RPM can indeed make a lot of noise that may even sound alarming - but really isn't. However, a fan that is making a "grinding" noise is bad, and indicates the bearings are worn. This fan needs to be replaced right away, before the bearings fail completely and the fan motor seizes.

As eidairaman1 suggests, if your computer was "unstable" you would be experiencing more drastic symptoms like sudden reboots, shutdowns, lockups. So please explain what you mean by "unstable".

If you really want to test this start with a virgin OS with just the motherboard and GPU drivers and not on the internet at all.

I agree. Or even just booting into the BIOS Setup menu, or into Safe Mode may give some better clues as to what's happening.

If you can honestly tell me you've never seen Microsoft Antimalware Executable using CPU/power when it's not scanning anything, and never once had to troubleshoot it misbehaving, then fair enough.

LOL So one-off anecdotal exceptions render an entire point moot? Not hardly. Anyone who's been around awhile has likely seen similar behavior with all sorts of security and other software that starts with the OS. Just because it is a mystery to you why a program is behaving in such a way does not mean the program is "stupid".

I wipe my ignore list clean once a year and five days in you're already argumentative and looking for a fight right out of the gate. Why are you even here?

There are hundreds of Microsoft KB articles fixing bugs with Windows Defender. It is not opinion or conjecture, it is Microsoft themselves admitting fault, documenting the many faults, and attempting to solve the problems they've created. There's no need to argue or make up some rhetoric to defend whatever asinine point you're trying to make, because the publicly documented issues are all over the web and detailed direct from the source at Microsoft. You can quite literally read through all the KB article descriptions to see a laundry list of problems, bugs and oversights.

Anyway, welcome back to my ignore list; I'm not quite sure why I bother wiping my ignore list because it seems that leopards can't change their spots, but thanks for reminding me why you were ignored in the first place.

You can use a fan control software to adjust the fan speed based on average cpu temp over the last 10 seconds. So a sudden jump won't make a big change to the average.

 

[Bill_Bright]

I am not looking for a fight - only the true and "unbiased" facts so the OPs and other readers can make informed decisions.

And I emphasize "unbiased" because clearly, you are not.

The OP not once mentioned he was using Defender. Heck, he didn't even say he was using Windows. Yet here you are launching another diatribe against Defender and those you believe are defending it.

welcome back to my ignore list

That's wonderful. Thank you!
