Thanks a lot for this information!
I am running mine with a cover (home-made) on top and no ducts, but under stress the rear CPU temp is really high (low 80s Celsius), and the fans are still running slow, although I'm seeing some evidence of CPU throttling (using i7z in Linux). I'm still looking at how to ramp them up in software. As far as I can see, there are no BIOS settings or mobo jumpers to adjust the ramp/speed?I'm pretty sure as long as something is on top to enclose and direct airflow it shouldn't be a problem. I'd definitely prefer to have them though, so please let me know if there's a part number on them
That's to be expected though... one CPU is directly behind the other for airflow, so the second one will naturally run hotter since its "input air" temp is the "output air" of the first CPU. The shroud does seem to force more air around the CPU heatsinks though, so it might be a bit better for keeping the second temp down.I am running mine with a cover (home-made) on top and no ducts, but under stress the rear CPU temp is really high (low 80s Celsius), and the fans are still running slow, although I'm seeing some evidence of CPU throttling (using i7z in Linux).

Edit: I should mention this is only with one of the two boards in the chassis on; probably will be worse with both...
Just a follow up for the thread, I received the risers and they work well. (the part # mentioned in another message. e.g. riser with 2x slots.)My box came in the first configuration, 10gig card no riser. After the thread I emailed the seller esisoinc and they said they would ship me the missing risers. Haven't gotten them yet but thought that I would report that they seemed open to making it right for me.

If you want to keep a PCIe slot open, you could get a 10Gb card on the mezzanine slot. For the OCP project there's definitely a bunch made by Mellanox, but Intel makes them too.Has anyone tested 16gb memory modules? I have not done it yet but am considering a dual node with (Per node):
- 2 2670 CPUs
- 8 16gb ddr3 reg ecc for 256gb
- pcie riser
- Intel dual port tengb nic 520 da2
- Intel 750 1.2TB ssd
- hp power supply modification
I am thinking this would allow one host to be primary and use Veeam nfr for replication to the second node and automated failover for maintenance. Potentially a drag ate 8TB smr drive connected to the main board for slower large storage.
Any ideas or input would be great.
Mine had part number dtafbf03028010130819 rev 3b which doesn't yield any Google results =\
Thanks, I think the Supermicro SNK-P0047PS should work, or am I missing something?Don't know the part numbers, but for the heatsink any LGA2011 compatible ones should work. The Supermicro ones are really well made, look for it.
They refuse to ship the missing parts.Thats terrible, why dont you contact them and ask them to ship you the missing parts?
Great Idea. Measured Mine and same holds true. As long as you have over 24" front to back between the rails it fits, added bonus is we can still mount 19" support equipment like PDU or 10GB switch. Thanks for sharing.My plan in to put it on a shelf and load it from the side of my 4 post rack. The 19" actual width still fits between the vertical posts just not at the very front and back where the holes are.
did you have the shroud on? you need it to help with cooling. if you don't just use a card board to cover the top should work as wellMy Quanta Windmill and 2x E5-2670 and 64GB memory finally came. But I have 2 problems. Can't seem to get USB booting from either ports. And the fan will go into "Jet Engine" mode and make enough noise to drive me crazy after a few minutes. There's nothing in the BIOS to check temperatures and I cannot boot into any OS to check temperatures!
What could have gone wrong?
I removed shroud for OS installation temporarily to let the graphics card fit into the pcie slot. Will put it back when OS is installed.did you have the shroud on? you need it to help with cooling. if you don't just use a card board to cover the top should work as well
