Try using hwinfo64 to monitor temps. It will give you current, max, and average temps. You may see small spikes in temps during gaming (again caused by transistor density). For example playing Wolcen my max temp seen might be 72c. However long periods of play average out to about 55-58c. But, 69c seems good for stock cooler.

Are you using the Ryzen balanced power plan? I have a 3900x cooled by an H110i and at idle I run from 29-40c with an occasional spike. Voltage reads from .360-1.15 volts at idle. What I would suggest is to go to AMDs website and download the chipset drivers direct from them. Once installed you should get access to the Ryzen power plan.

Are you using Ryzen balanced power plan? If not update your chipset drivers directly from AMD. Once you do that the power plan should be available.

Looks good! You probably won't get lower temps on the stock cooler. Your idle voltage looks way better. Takes my chip an H110i to idle in the high 20s-low 30s, and it will spike sometimes (can't do much about that due to transistor density). What's normal load temps like say while gaming or something?

No worries! Hope it helps.

Setting DCOP to 3200mhz is fine. Not even an OC actually as the chip is rated for that. I'm gunna guess you do not have the most recent chipset drivers installed. Go to AMDs website and download the latest chipset drivers from them directly. Also make sure windows is up to date. As long as windows is up to date the driver software will install the Ryzen balanced power plan.

Idle voltage seems high. Are you runnung Ryzen balanced power plan?

Out of curiosity what speed is your RAM running at?

used cpu-z for voltage read

Also on Crosshair VIII Hero. I just enabled D.C.O.P. and left everything else in UEFI alone. After installing and updating window I got the latest x570 drivers right from AMDs website. Enabled Ryzen balanced power plan in control center.

Go to AMDs website and download the latest x570 drivers, also make sure windows is up to date as well (in settings/system/about/version should be 1909). As long as windows is up to date the chipset drivers will install the proper power plan.

Seems good especially with the static voltage. My 3900x voltage is set to auto. Idle temps are around 29-40c. Voltage can bounce between 0.336-1.16v. Using an H110i.

I actually have the hyper 212 black edition on a 5930k when it got moved to be used as a secondary system. Quite pleased with how well it works.

That seems high. What's you vcore look like at idle? Are you using Ryzen balanced power plan? I have a 3900x that idles at 29-40c with voltages between 0.336-1.16 at idle. Using CPU-z for voltage info. That's using an H110i.
