Idle temps are 58C under water.
used thermal grizzly thermal compound.
CPU Block is Hydro X Series XC7 Water Block
2x Corsair Hydro X xr5 360mm radiator's
room temp is about 72F
water temp according to iCue is 27-32c
Case is Corsair 500D air flow with 10 fans (6 in, 4 out)
Motherboard has updated Bios and is ASUS Strix x570-E

doing blender test (Classroom) thermal throttles the CPU as it reaches 84.5C

You might want to look into changing a few default Asus UEFI settings. By default, they enable MCE (multi-core enhancement) which really pushes the CPU into very aggressive clocks and voltages.

When I disabled that on my Asus motherboard, my Ryzen 2700X ran much cooler.

How would this impact performance?
others have suggested that perhaps I have to much thermal compound.

I guess I assumed with your listed components in your OP, you used the correct amount of thermal paste.

Maybe that should be your first step to check.

Yeah something's gotta be wrong with your cooling setup, if those temps are accurate.

I have a 3900x with a similarly-oversized WC setup: a MO-RA3 rad with 9x120mm fans and a Heatkiller IV Pro block with two D5s. In Blender 2.92 benching classroom, I barely get temps of 62C. My chip has the same 142W power limit as your 3950x so the temps/cooling situation shouldn't be that much different.

I agree that somethings up with the cooling setup with those temps. The amount of thermal interface material won't make any difference unless you don't use enough. Too much just means that you made a lot of mess.

I'd pull the pump, check the spacers and mounting setup, check the contact area of thermal paste, clean everything and reapply thermal paste

there's several articles on this, here's just one. Thermal Paste on the CPU: Consequences of Putting Too Much or Too Little | ITIGIC
