Ryzen 3700X Idle Spike of 10°C at 40-50°C

[Scotch]

Hello folks,

I recently received my new build from PCSpecialist on Sunday. I have a concern regarding CPU Idle temperatures and spiking. There has been a few posts I found across the internet stating that Ryzen CPU tend to spike, but still causes concerns.

At Idle my CPU temp is sitting between 40-50°C, but every 5-10 seconds it will instantly jump up by 10C to 60C then slowly go back down to its previous temperature. I also hear the fan speed up and slow down. I'm additionally using Noctua NH-U14S Ultra Quiet Performance CPU Cooler, which should remove any form of cooling issues.

When idle not ever had an experience the temps being so high even at 60°C. I have some what found a workaround where if I use power saver mode my temps stay stable at 35°C constantly.

If anyone has any advice on how to prevent temps being so high and spiking when not in power saver mode it would be really appreciated.

Thanks

During the first few days it's quite common to see Windows doing lots of configuration work In the background - drive indexing for example. In addition, Windows is rarely truly idle, there are many Windows processes that run when the system is otherwise idle.

I see my CPU temps spike every now and then - my keyboard colour changes with temperature so its very noticeable.

Can you post your full specs from the order page?

Please find attached PC Specs @SpyderTracks

@ubuysa That is understandable, especially with background downloads etc. The fact that is consistently spiked CPU temps 10°C every 10 seconds for hours. Just seems like it is automatically boosting itself. Which I somewhat don't mind. But when idle temps hitting 50 then jumping to lows 60's is concerning. I appreciate you taking the time to reply

It does also depend on what you use to measure the temperatures...for example on my 3600, when I look at temps using AI Suite 3, it bounces around between 40 and 70 while doing nothing; CoreTemp it bounces between the low 50s to mid 60s, same with CPUID HW Monitor

I believe it is more to do with the Ryzen temp sensors than the temps actually being that high as there is no real overall difference with my temps regardless of what fan profile I run

Thanks for that, I have been using HW Monitor and Speccy to read them. Both showing very similar scores. But could be a temp reading issue.

If they sit at those "Stated" temperatures for a prolong period within idle, will that not reduce the products life span?

No, not at all, it’s only if they raise out of spec and constantly thermal throttle that there would be a risk to longevity.

If you monitor your cpu usage with task manager, you may find as @ubuysa says that there are a lot of tasks going on in the background such as indexing and it’s not at all idle. This is normal on windows 10 for the first few days of a new installation.

What’s more important is the load temps, if they’re reaching out of spec then it suggests a paste issue which would need to be addressed.

Ohh, well that is a relief. Always been heavily concerned with CPU temps since my first PC disaster of not reapply thermal paste after many years of heavy use.

Thanks for clarifying @SpyderTracks , then for the time being I will just leave it for a week and come back if needed.

Still haven't had time of yet to really test out the pc potential so not 100% sure how it will run with higher demand.

Maybe you could help me understand how is it that my CPU is stable at 35C with no fluctuation on power saver mode, while running same processes? I am aware it is running about 0.5V less than normal mode.

From what I have read before, it is a particular quirk of some Ryzen chips that the reported temperatures fluctuate quite a bit even at idle....I just read that AMD, in some Ryzen chips, deliberately coded the sensors to report 20 degrees higher than actual to ensure good cooling (no idea which chips or whether that is still a business practice)

I did read that as well that temps are "apparently" set higher. Very strange though practice

Power saver mode effectively underclocks the CPU, so it draws less voltage and produces less watts (heat).
