At 22C ambient, under Prime95 smallest FFTs, XSPC Raystorm (original, not pro or neo), my 3600 hits 76C 4.1GHz at 1.35V and roughly maintains that frequency. I should note that this was after I greatly tightened down the corner screw nearest to the corner chiplet on the 3600. I don't know if the Raystorm was just not making good contact with the IHS of the 3600 or if putting more pressure on that corner helps because there is a chiplet under that corner. Before tightening that corner all the way down (while leaving the others a few turns looser) I was still hitting 95C under full water.
What version of prime did you run ??
Look at my sig (custom loop), when running prime95 29.8 build 5, PBO on auto, 3800/1900 mhz, using blend test I see peaks of almost 85C.
Does the version you use have AVX2 ??

If we go by past Ryzen chips, you're looking at ~20-22W per core and the only time that would make sense to watercool is when you have 10+ cores. 8 cores would have you at ~180W which is just above the TDP rating of a decent 4 heatpipe cooler and a 6 heatpipe cooler would give you enough thermal headroom with reasonable fan speeds.
Although im in agreement, the more cooler these CPU run, the more consistent and better performing the results are.
Also those of us who already have custom loops we will of course still use them with any CPU
Ive attached a screen shot from a 12+ hr prime95 blend. You can see the relavant information
Im also attaching a picture (the 'ridgy' area is a overlay of how the conductonaut spread) of how my waterblocks head sits on the IHS and its position relative to the CPU and I/O die.
I contacted EK regards the fins positioning but from their answer seems like they are not interested in redesigning a different head for my monoblock
Im very interested to see more results in this thread, hope others will participate soon
