wow talk about a mega socket...

i have not seen a heat sink so far... im assumming its gonna be a vendor exclusive with complicated air shroud.
Given this is effectively an enterprise only socket (at the moment at least), you're going to have a hard time finding non-enterprise oriented heatsinks. What is this system being used for and what is it going in? I don't see Skylake-EP/EX out yet which would mean this is a Xeon Phi build or just future planning. If Phi, besides the fact those aren't designed as general purpose processors, they're a 215w-260w TDP. That's going to require a pretty significant amount of cooling. The SNK-P0070APS4 is listed as 38db which isn't shabby considering what they're having to dissipate. Noctua's Threadripper cooler is listed at 23db and that's a 180w TDP.
Fair enough, didn't realize those were LGA 3647. Does beg the question what they are using all that die space for considering the specs on that processor. Either way, I'd suspect you're going to need to wait a few months to see any consumer oriented products. Or make your own. Buy the previously mentioned SNK-P0070APS4 and replace the fan with a Noctua. Given you're only dealing with an 85w TDP, that shouldn't be a problem.
Yeah, kind of wondering, "Why not ThreadRipper?"just trying to understand the desire to go with LGA 3647. What are you gaining going with that? It doesn't sound like you've bought anything yet that would lock you into that choice.

Because most people building servers want features not available on consumer boards. Namely IPMI and multiple Intel GbE or 10GbE NIC's.
If $250 isn't a big deal, I'd get the one with 10GbE onboard. You can still use them as GbE ports in the mean time and then when you get 10GbE switches you don't have to power a server down and swap hardware.
However, there's one caveat. 10GbE NIC's run really hot. In the servers in my sig, they are the hottest component in the system. Since you have noise concerns, it's something to keep in mind.
Fair enough. Just for reference, the 10GbE chip is running 15c warmer than the E5-2670 V2 in the same box with enterprise fans.
BB the nic isnt a problem...
You can get a intel 10gbe for about 100 dollars on ebay:

The problem is the switch.
Its because it bascially needs to be a PC with multiplul 8x PCI-E lanes to handle 10GBe Traffic.
So they get quite costly.... very costly...
I Dream of getting a reliable + Cheap 10gbE. AS i would love to tie my NAS's with my Server together on a 10GBE line, for faster file transfers.
But until then... sigh.... im stuck on LACP with a managed switch....
So, do you think that is a problem? I value your opinion. This is what you do.
Hard to say without knowing what else is going in the build and case/environment details. Also, what have you already purchased or are you dead set on LGA 3647?

That's a Supermicro 6027R-72RFT with 3x 7,000rpm fans on "power optimized" mode (3,700rpm at the time of the above picture). Room temp is 75f. Nothing's remotely close to danger temps but that's with a lot of airflow, no GPU's, less than half the memory slots populated, and decent room temps.
I'm thinking of building a Tower / 4U system) around a Supermicro X11SPM-TF (https://www.supermicro.nl/products/motherboard/Xeon/C620/X11SPM-TF.cfm) and an Intel Xeon Silver 4108.
I asked Supermicro Technical Support about low noise CPU coolers such as a Noctua and was told: If going for something like a Noctua then please be aware that we generally don’t support low noise fans, if the fan starts spinning under about 700RPM you can start seeing issues with the fan constantly revving up and down as a result of the system going into a “panic” mode, revving up all fans to maximum when a lower threshold is reached.
Noctua Technical Support confirmed this and stated: Most of our fans spin at around 300-500 rpm at idle. This often causes issues with Supermicro motherboards as it interprets the low fan speed as a failure. As a result of that, the motherboard would make the fan spin up constantly. The main issue in your case is that we're still working on LGA3647 coolers. They should be available sometime this summer/autumn.
Added this reply as it might prevent others from making a costly mistake. The only suitable CPU cooler of which I am aware is the SNK-P0070APS4 (https://www.supermicro.com/ResourceApps/Heatsink_Matrix.aspx).
I would be interested to hear of any other quiet LGA 3647 CPU cooler options for 4U enclosures where the idle spin speed is above 700 rpm. A quick look at the PWM fans on QuietPC.com (https://www.quietpc.com/casefans) didn't find any with a minimum speed above 700 rpm.
