I would watch your CPU voltage under load to see how high it goes. If you are running "stock" BIOS it probably has a few overclock features turned on by default. I know MSI does that, my i9 10900K was getting cranked up to 1.55v+ under load because the motherboard defaults are set to just crank up the voltage for stability, but if you don't have a strong enough cooling solution, you would see crazy temps. In my case, even 3 360mm radiators were barely keeping my 10900K under 90C because it kept doing that... if I just set up a static voltage even at 1.4v I was hanging in the 30-40C range under load.

Heads up on the Conductonaut and the CLC 280, it will leave a residue you will never be able to remove from the copper block on the CPU cooler. That's what happened to mine... It's pretty much the best you can get for thermal conductive applications but it can get really messy really fast. Make sure to watch a few videos on how to apply it first if you go that route... I had a few too many instances where it just required too much time to get everything clean, even then I still randomly find a small bead of that stuff pop up on hardware I used that on years ago. I pretty much use EKWB's Ectotherm for everything... I have a bunch of that Thermal Grizzly Kryonaut but it's old or something and it doesn't spread as well as the Ectotherm, so that's what I use.

I decided to go with the Kryonaut because I didn't want to leave the residue with the Conductonaut (I did a bit of research before going forward).  If I get to the point where it is an absolute must I might switch.

The ambient temp in the room with the computer is probably around 80F.
The current specs on the system is:
AMD Ryzen Master
42C+/- on idle (2% CPU load)
 
EVGA Flow Control
47C+/- (2% CPU load)
34.7C Coolant Tempt
 
MSI Control Creator
45/50C (2% CPU load)
32C+/- Case Ambient Temp
 
Under load with basic editing of 4K footage in Premiere Pro the temps haven't gone about 66C that is usually at about 25% CPU load.  Rendering hasn't gone about 76C
 
I also undervolted my CPU .05 and that helped a little and boosted my Cinebench score - haven't gotten into overclocking yet.  Will do more testing soon.
