What is everyone using for a CPU heatsink on these? I'm hitting a brick wall. The cpu socket is rotated 90 degrees similar to other server motherboard setups so nearly any 1851 regular heatsink doesn't work as it goes top to bottom instead of front to back out the rear. Since I've got this in a 4u case it wouldn't work right as it doesn't align with the air flow.

This is what I used on my SM motherboard. It works extremely well with idle temps at 28F and fully loaded temps at 65F. It does allow for front to rear fan orientation.

Thanks, so do you have it oriented so that the metal bottom plate of the heatsink that is a rectangle is perpendicular to the rectangle shape of the CPU? Not aligned with it? The peerless assasin one I think is the same way.
ie I was worried that putting it that way would not cool it adequately as the contact area isn't an exact match for the cpu as it is 90 degrees oriented differently. Obviously graphics below are exaggerated a bit, but you get the point

What motherboard are you using?
On the SuperMicro X14SAE-F the CPU on that board is oriented the same as most other Core Ultra motherboards I've seen.

Ah yes, lucky - the Asus w880 has it oriented differently =/ Why the hell did they do it this way.... I've got a Noctua NH-D12L on the way that you can rotate it. I obviously didn't notice that when I bought it, and almost went with the Supermicro... was just going to take longer to get here
Another thing crappy about this board is the 2x 4x4 Power plugs, had to get extensions for the Supermicro 4u powersupply as they are halfway across the board.

You could always go with a liquid cooling solution since the fans are on the radiator and not the CPU.
Crossed my mind but I'm using a 4u supermicro case, so it would probably have to be external and take up space in the rack.
it's very common for server motherboards to have the RAM slots run horizontally rather than vertically. it allows better airflow over the RAM.
You know if you have a 3D printer or just some skill with cardboard and zipties the fans on those tower coolers don't have to point the way the manufacturer attaches them, they could do a pretty good job blowing sideways if you add a baffle between the tower sections and maybe a partial shroud around the outside to convince the air to flow through the fins.
Thats next step if this noctua doesn't work (looks like it will comes tomorrow). Unfortunately the top side is where possible Sata/u.2 mounting is and bottom close to the PCIE cards - the heatsinks are pretty massive.
I have a Prusa but my 3d printing design skillz have a lot to be desired
Ya, all my other motherboards (dual proc etc) ones are like that - good point on the ram cooling never thought of that. The server mobos by default just had heatsinks/baffle with no fans. Just didn't expect to see it on the w880 board but it does bridge the gap between server and desktop board.
With RAM and even SSD and hard drive prices becoming insane. The only hack would be to buy a preconfigured computer built and sitting on a shelf before the RAM prices skyrocketed.
I know some people are buying a lower-grade box (not the 32GB or 48GB sticks being asked about) by purchasing from Costco and harvesting the RAM and SSD drives at a savings for less than a standalone package of RAM. There are also some used options on Craigslist etc..
I ended up ponying up 820~ bucks for 96gigs of ECC =/ from mem-store about two weeks back. Checked today and it's already at nearly 1k. Sad state of afairs as it's probably going to be a good 1.5 - 2 years of future increases.
Was there anything special you did to get the 4 sticks working? I've got 4 sticks of 48gb from mem-store and they work as each pair, but I can't get them to post with 4 of them.
I've dropped the speed down to 4400 instead of auto (as per Supermicros manual) but can't get it to work. The supermicro board does not have any timing settings I can tweak.
I thought you had the ASUS board as you mentioned above? I did not have to do anything to get the memory I have (4 x 32GB) to work. The X14SAE-F does support 4 sticks of 48GB according to the manual.
I actually have both boards - 192 gig works fine on the asus, does not on the supermicro.
