they work. but cooling can be an issue if FANs are in a row.
I remember asking you about coolers long time ago. Basically since then I've used what you've recommended - a pair of NH-U12S - officially they are incompatible with MS73, but in reality they fit, however putting fans back on the cooler is harder than it should be (you can't put your fingers between the coolers, so you need to push the bracket in and help yourself with a screwdriver if needed).

not in a server chassis with air shrouds...
Yeah, true. I was about to say that I'm not sure if something like Arctic Freezer 4U would fit and if it would work properly as it would be basically getting hot air from the other cooler. And I can see how 350W might be a problem if you use something like Dynatron S5R1 or S6

Is it worse than 40c air coming from a big array of disks in the front of the chassis?
it is around 50-60c celsius. the problem is the second CPU gets 20c hotter.
heatpipes need temp. delta to work.
to be precise:
sure this works. it is easy because just physics.
with enough Airflow you can handle this.
but your neighbors will call the police because they'll think you're building a jet plane in your living room.

Yeah that makes sense. And how did you know the server I was referencing was in my living room ;)

I need relatively high fan (~4000RPM 80mm fans) speeds to cool my 7V73x to just 60C at idle with preheated 40C air! Luckily the P8 Max fans are not very loud at that speed.

Crazy idea - for the dual CPU case - have the heatsink be exhausting opposite directions, so one exhausts forward and one backward?

you need airflow over motherboard. server mobo are not like WS boards with Heatsinks on every chip, they need continous airflow.
somefriends tried 2x 8251C in Dell T7920 - no way without water.

That's a good point, wasn't thinking of the VRMs and NICs and such.

Depends on the board, but in quiet a few cases if you won't put fans, VRM and/or NIC would overheat quickly. I usually put small 40mm fans in a desktop case near those places and that so far was enough.

BIOS 1.0 for X12SPL and X12SPM supports step 4,5,6 (QWxx/QUxx/QVxx)
X12DPi supports QUxx/QVxx up to BIOS 1.1a
QWxx step 6 is supported by all BIOS/models
Just to confirm, even for BIOS 1.0 X12DPL doesn't support QUxx/QVxx?

correct. BIOS 1.0 X12DPL is officialy available for download (STDsp)
BIOS 1.0 for X12SPL,X12SPM not (TESsp)
STD = Standard BIOS
TES = Test/ES BIOS
sp = signed production key/cert
sd = signed debug key/cert <<-- can't used without also having the debug key/cert.
e.g. STDsp,TESsp is accepted by RoT, TESsd not.

(or anyone with a MS73-HB1) have you updated R10 or R11 bios? I'm on R07 but I'm worried they'll pull support for ES CPU's.
they don't.

RelNotes R11 :
1. [Feature] Fine-tune Redfish display content.

btw: you can back to older BIOS at any time (BMCWebGUI)

only QS = prod.unit with ES bit set.
Yeah, though on previous page there were E5 ESs (in a sense of having production stepping, but at the same time not displaying product string) on screenshots for server Xeons, so I hoped maybe similar thing happened with Xeon-W this time. But I guess - no...
