Heating issues

I built my pc just over a week ago. I am running the Ryzen 7 7800X3D with the ASUS X670E-E Gaming motherboard. Initially the temps were around 45C to 50C at idle however I was facing some problems with the ram running at high speeds. The system would not post if I set the speed to anything above 5000MHz and had to perform a bios flashback to get it running again. I was not confident on updating the bios but finally decided to do it around 3 days ago. Now, after the bios update the ram runs at 6000MHz but idle temps have been ranging from 50C to even 63C. I ran Cinebench R23 3 times non stop the max it reached was 82C. I am using the Asus Ryujin III 360 AIO.  Did Asus get around to fixing the voltage issues on their motherboards for the AMD X3D processors? If not should I manually try and undervolt the cpu? I am running Bios version 1709.

Hi buddy, as an Intel man, I can't comment too much on AMD stuff but I do know that undervolting on either platform is now pretty much a given since the out-of-the-box settings on most motherboards ask for far to much vCore / SoC voltage.

 

Assuming the idle temps you detail are normal for AMD processors and you don't have any problems with how the cooler is seated then knock some voltage back from the CPU and take it from there.

 

Like I said, I don't know what the baseline / norms are for the recent AMD processors so hopefully someone else here might be able to give you a better idea on that front.

Temperatures seem fine to me. ASUS did fix the voltage issues in later BIOS revisions so you are safe.
The AM5 7000 series will always try to hit a temperature limit before anything else, they are designed completely different than ANY other CPU's on the market. They WANT to hit a max tempeature before clocking down etc. Seeing 50-60c idle is very common and your Cinebench temps look great.

Please check out the the 2 videos, they are the same video as you can tell but timestamped correctly to explain how they work.  Hope this helps.
You can also check out Jayz's video on this matter, its a long one but fun with a lot of information.

A bit high but not really worrying

Did you try undervolting /Curve Optimizer ? It was already good on Zen3 but seems miraculous on Zen4 to manage temps
