Good afternoon! Does anyone have MS73-HB1 on hand? Could someone please suggest the dimensions of the VRM radiators? While the motherboard is being delivered, I want to make custom radiators, otherwise it hurts to look at complete radiators (I'm afraid to imagine what temperatures VRM/MOS are at maximum load).
View attachment 41791
Here is me haphazardly shoving tape measure. Can't find my meter... looks 3 and 3/8 inches, or 25.5mm long?

VRMs get about 120c hottest I've stared at. On full load with 8592+, without small 20mm fans i put on there. About 90 otherwise after 24 hours. Running other first board I got with 8480s and with nothing but water blocks, terrible decision. Glued overhead fans on my radiators before to get some flow across those... Any and all flow will drop temps on these nicely.

There was some maker making full VRM waterblock for MS72, tried asking them if they commission set for MS73, said no. Forgot their name though.

Is there a place to download X12DPL-NT6 BIOS version 1.00 to work with the earlier stepping ESes?

thanks. what's the earliest ES that BIOS 1.0 supports? QWxx, or does it also do QUxx/QVxx?
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

you want not realy work with BIOS 1.0
if you look at the RelNotes/changelog you have to manage hundreds of bugs, lack of functionaly etc.
but if you realy try: good luck !

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.

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.
