As the title asks, I'm looking for a hsf for LGA 3647 or Socket P. I know it's only been out a month or so, but I swear I read of prototypes being exhibited a year ago.

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.

Noctua had a prototype they used in June 2016, using a modified current model. However, they have no plans on making it for consumers. They hint that they may have a socket specific model in a couple of months.

Super Micro has two active coolers, one for 2U and one for 4U. Both look noisy. In an enterprise environment, I'm sure they don't care. Me in my home office, I sure as hell do. I really wanted to start putting a new server together. I've started assembling the parts. I'm waiting on getting the motherboard, CPUs and heatsinks last so that I can return promptly anything that doesn't work. I was hoping that someone would have a consumer solution available.

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.

I plan on using a pair of Intel Xeon Silver 4114 @ 85W each. It's Skylake-SP. I was going to get the Xeon E5-2630v4, but decided to get the latest generation. It's just for me to learn and play on.

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.

I really wanted to go with the Noctua NH-U12S, but it's not compatible with 3647. You ever get the itch to do a build and then have to wait. I've been waiting a long time on this project. I planned it out six months ago. Decided to change the mobo and CPUs yesterday after I found the older motherboard support for newer parts to be lacking. Now, I'm having trouble finding a consumer HSF. LOL

I get the itch factor, I'm just not sure what you're wanting/needing that requires the new platform? I've got NVMe drives and 10GbE NIC's in the Sandy Bridge servers in my sig. Only thing they're missing is USB3 but honestly they're servers and I haven't had a need. Not saying to go the used route, 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.

Yeah, kind of wondering, "Why not ThreadRipper?"

Because most people building servers want features not available on consumer boards. Namely IPMI and multiple Intel GbE or 10GbE NIC's.

Hey XM, do you think there's any reason to get the mobo with a couple of 10GbE nics on-board? Do you think that 10GbE is not quite there yet in the consumer world? I know I could just add in a card later. However, they have a model that has 2 x 10GbE and 2 x GbE on-board. The other similar board just has 2 x GbE. The price difference between the two is $250.

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.

This is not mission critical. I will not be using a redundant power supply. It will be very reliable, but if there is a failure I'll just have to replace parts. I ordered six Noctua 2000rpm 120mm PWM fans. There will be plenty of air moving through the case. It will not be silent, but not obnoxious like those high rpm enterprise fans. :D

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:
http://www.ebay.com/itm/Intel-OEM-X...878946&hash=item2cbbf94529:g:7lgAAOSwwzhZWiij

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....

Well, I think I'm going to delay the project in hopes that a consumer cooler will be available in the coming months. I'm going to update my storage for the time being and then migrate that over to the new build when the time comes. I just can't see myself living with that noise for more than a few days. I don't mind a little noise. It's the intrusive nature of smaller higher rpm fans that get to me. In a closet or in a server room is different. I don't have to sit next to that for hours on end. But this will be sitting right next to my desk. In the pic, I'll be replacing the computer on the right.

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?

20170820024547-633f3c5e.png


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.

Cool. You've already done what I would like to do. What do you need two machines for? I plan on using an E-ATX tower case with larger lower rpm fans. I can't imagine there's any problem cooling a pair of 85W CPUs. I will just be patient and wait until they come out with a cooling solution for my application. Like I said before, I have to live with the machine in the same room.

I could have gone with LGA 2011-3, but once I decided to go new (instead of used) I decided to just go with the latest generation. At that point, there is not much of a cost differential. I already have the power supply and case. RAM, case fans and NVMe are on the way.

I'll probably add to my current storage with a pair of 10TB HGST HDDs and move them over when a consumer cooling solution comes available for the new build. I'm not so much in a hurry that can't wait a little longer. I'm upgrading the video card in my main rig from a GTX 970 to a 1080 Ti this week. That will keep me busy for a bit. I'm also shopping for a 4K monitor. Any recommendations?

I don't "need" two hosts. I like having two so I can keep things running when I do maintenance, and I use replication to backup my SAN.

CPU's I'm not worried about, they've got massive heatsinks on them. My bigger concern is the other components. IE 10G, and NVMe drives. Like I said, mine aren't near danger temps, but you also don't want to be in the same room as those boxes.

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.

I'm sure you could find a fan that ran 1500 rpm. That would be a lot quieter than those officially supported ones. I'm just waiting for Noctua to come out with a heatsink.

You might consider installing EKWB water block. They’ve just released it. https://www.ekwb.com/shop/ek-annihilator-ex-ep
