I bet you would see astonishing low temps with Conductonaut because the IHS is soldered (using STIM, or Solder-TIM) to the internal chips in that CPU, which is great.
 
Food for thought, but there's not a thing wrong with the temps now.

* Corsair Obsidian 450D Mid-Tower - Airflow Edition * ASUS ROG Maximus X Hero (Wi-Fi AC) * Intel i7-8700K (Delidded, TG Conductonaut) @ 5.4GHz* 16GB G.SKILL Trident Z 4133MHz * Crucial MX500 M.2 1TB * WD Black 500GB (x2) * Seasonic M12 II 750W * Corsair H115i Pro * EVGA GTX 760 SC * Dual-Boot Win7 Home 64-bit/Win10 Home 64-bit (Winver 1909) *

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 just watched this video from Gamers Nexus https://www.youtube.com/watch?v=BbGomv195sk
Very informative.  I had my AIO mounted on the CPU with logo up, which also meant that the tubes were on top.  After watching the video I swapped it so that the tubes were at the bottom when mounted on the CPU.  Initial tests brought my CPU temp at idle down to around 41C constant (I was getting readings the other way around 46C-50C even after a the previous post - it went back up a few degrees) and 100% CPU usage is around 70C. (not running very long though, so it might go up a few more degrees)
 
My next task is to investigate what JayzTwoCents shares in this video - https://www.youtube.com/watch?v=R460NL_wdGc
There is also this one on Gamers Nexus - https://www.youtube.com/watch?v=JscRwIH3OAY
I am getting some heavy fluctuation in CPU MHz and Voltage, so there are a few tests he did in the video that helped stabilize those and maybe it will be another way to help keep temps down.
 
A Few Hours Later:
I am getting temps with about 30% CPU usage using Premiere Pro and After Effects at 52C+/-, but the numbers change depending on what software I am using.
AMD Ryzen Master: CPU-52C
EVGA Flow Control: CPU-60C, Coolant Temp-38.1C
MSI Creator Control: 56-59C but CPU Usage is saying 3-7%
 
It still looks to be manageable as far as temps for now - it would be nice to figure out how to keep temps a little more consistent though.

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.
