Well. Here is my experiment with Ryzen 9 3900X.

Processor: AMD Ryzen 9 3900X.
Motherboard: MSI X570-A PRO.
Memory: G.Skill Ripjaws DDR4 3200 CL14 XMP 2.0 ( F4-3200C14D-16GVR ).
Air cooler: Bequiet Dark Rock Pro4.
AIO cooler: EVGA CLC 280
PSU: Corsair HX1200i.

Out of box: 10500 hash/s

Memory DRAM Calculator for Ryzen v1.6.2. https://www.techpowerup.com/download/ryzen-dram-calculator/
Processor: Ryzen 2 gen
Memory Type: Samsung B-Die
Profile version: V1
Memory Rank: 2
Frequency (MT/s ): 3200
BCLK: 100
DIMM Modules: 2
Motherboard: X570

Calculate Fast.

Room temp: 23C

CPU: 4.0 Ghz @ 1.2V - 13150 hash/s @ 230W wall
Cooler:
Default cooler ( Wraith Prism): 90C
Dark Rock Pro 4: 75C
EVGA CLC 280: 67C ( 1200rpm fan )

CPU: 4.2 Ghz @ 1.25V - 13500 hash/s @ 280W wall
Default cooler ( Wraith Prism): +++ better dont try +++
Dark Rock Pro 4: 84C
EVGA CLC 280: 73C ( 1200rpm fan )

anything over 80c will destroy your cpu in a few months

My 3x ryzen 9 3900x all use water coolers.

I have an

evga cooler = https://www.amazon.com/EVGA-Liquid-Cooler-Cooling-400-HY-CL24-V1/dp/B074WH52BW/ref=sr_1_1?
corsair cooler = https://www.amazon.com/Radiator-Advanced-Lighting-Software-compatible/dp/B077G3C6HH/ref=sr_1_4?
fractal cooler = https://www.amazon.com/gp/product/B0719DHG5Y/ref=ppx_yo_dt_b_asin_title_o05_s00?

yet to test

cool master cooler = https://www.amazon.com/Cooler-Master-MasterLiquid-Dissipation-MLW-D24M-A20PC-R1/dp/B075YPG52N/ref=sr_1_3?

and yes the corsair 280mm is best at 66C full speed
the evga 71c
the fractal 69c

what do you consider full speed? 4200 mhs is what i would consider
around 1.25 to 1.3 core to allow for close to 13k hash . do you get 13000+ mhs on the water cooler?
