Epyc 75f3 cooling choice?

[sth]

Acquired a Epic 75f3 which will be going in a Supermicro SC846 4U chassis with H12SSL-C and 512GB 3200 RAM.
It's a 280W CPU and choices appear to be somewhat limited and results hard to find re cooling performance.
Dynatron A35 or SNK-P0064AP4
Noise isn't a concern? Does anyone have data showing cooling performance under load to compare these two choices?

If you have 4U to play with, Freezer 4U SP3 | Server Cooler | ARCTIC and if you want to play with some fans, there's 3D-prints/Arctic Freezer 4U SP3 120mm fan adapter at main · barichardson/3D-prints

Success story with H12SSL 846 and Arctic 4U SP3
I not sure it will work with that adapter and exhaust fans unless mounted outside somehow

Arctic SP3 4u Rack Case Compatibility list

Thanks! That was the photo I was after. Zipties it is then, if I ever receive the cooler. In the mean time I found used Noctua TR4 cooler, I guess that’ll work for now

I cannot locate the Arctic Freezer 4U SP3 to purchase. Not sure what is up with the global stock.
Not a lot of "good" air options for an SP3 (Milan) that I am considering to OC.

@slidermike I got this answer from Arctic

Hi rtech,

thanks for your request.
The Freezer 4u SP3 has gone end of life and wont be produced anymore. Soon the successor will be released around September circa.
The new Cooler will be called Freezer 4U-M.

The new ARCTIC Freezer 4U-M is now available to purchase from Arctic through Amazon.

I use an A38 on a 7763 and it's fine but noisy when under full load. 4U-M definitely would be a better choice but I'd rather upgrade to water than another air cooler.

I am new to the server cpu market but the two things i have read are:
1 water cooling is expensive and limited choices.
2 for air coolerd the arctic freezer is top dog with excellent thermals.

I do have a ryzen 5900x that is water cooled by an arctic 320. Works great and super price point.

My generic air cooler on the epyc 7543 is mediocre at best. I finally found an arctic freezer 4u and its arriving next week. Based on all the reviews i expect much better cpu thermals under load than the current cooler.

Let us know which water cooler you get @KaneTW .
