[SOLVED] Alarmed by CPU usage Ryzen 3700x

[DarthBatman]

Hey guys I'm new to PC's build and I recently completed this set up. Ryzen 3700x, msi x570 gaming plus MB, 32gb ram(3200), EVGA 2060 KO Ultra 6 GB, 500 m2 nvme SSD

Currently use this as an editing machine with a little bit of halo reach here and there. I did some minor editing work today in Davinci Resolve and I thought the CPU fan was a little loud for the workload I was doing. It was simple cutting in a timeline, the footage might have been 4k though I can't confirm that.

I did this about 2-3 hours ago and noticed the fan was still loud. So I just booted up MSI Dragon center and was somewhat alarmed to see that my CPU usage was at 79-81%. I was sure that I closed Davinci Resolve when I was finished and I opened task manager to confirm this as well. I attached some photos here of Ryzen Master and Dragon Center.

My main question is whether this is cause for concern or not? Wouldn't the CPU reduce it's usage relatively quickly after the appropriate task? All I've done the last hour or so is browse the web and watch youtube videos. I also notice discrepancy in Dragon Center temperatures and Ryzen Master Temps. All in all i'd love to get this machine to run a little quieter unless it really needs to.

Okay I may have discovered one problem here. I recently downloaded Ryzen Balance power plan and was sure that I set it to the Ryzen Balance setting. I just double checked my power options and somehow it reset to Windows 10 Balanced. So I changed it back to Ryzen Balanced and will reset the computer to see what happens. Is there a way to ensure this change is saved or should it be automatic?

Okay so when I restarted the computer I had some windows updates to install. Once I got back into windows I checked the power plan setting again and it keeps going back to Balanced(Not Ryzen Balanced, just Balanced). So I changed that yet again and specifically changed the power off screen setting to 15 minutes so I could have the option to save something.

Dragon Center now says I'm 0-6% usuage. Idle temp is ranging from 40-49 C

All power plans are customizable and except for defaults practically same. If you set Minimum processor state to 5% and maximum to 100% you get best range of frequency according to load. Maximum set to 99% will limit maximum frequency to CPUs base frequency.
CPU usage % is not tied to any power plans but only what OS and SW demands,best place to find it is in detailed Task manager where you can see what is keeping it up.

+1 to what count Mike said.

Power is independent to cpu usage. Open task manager, expand the details and click on the cpu% column to see what's eating your cycles up.

It's possible an installation program, system update, or virus scan is causing the issue. But its also possible it's a mining virus. Make sure your anti virus is up to date.
