Question Noctua NH-U12A not suitable for GIGABYTE Z790 Master?? Big problem - help!

[mamanana12]

I just came back from the store and as you can see in the picture the fan of the Noctua NH-U12A chromax cannot sit properly because the memory (2) "gets in the way" - The fan then sits above the ram stick
The case is Fractal Design Torrent Black Solid btw

I'm afraid I have to compromise on the cooling of the processor (Intel Core i9-13900K) - How does such a thing happen on such a large motherboard?
I don't know what to do
Will there be a difference in the temps because of it? Did the seller install something wrong? Are the sticks of 2 and 4 necessary for the stability of the system? (3 and 4 will make instability?)
I'm going back to the store tomorrow to complete the built of the pc - any advice and tips are welcome!!

I see a green "V" on NH-U12A chromax.black there!

Which makes this event more strange
Can someone try to explain what is going on here?

 

[Lafong]

Might be an easy explanation.

I can't tell much from your pix.

What case are you using?

Any other variables?

If more information is missing, ask specifically and I'll add it
The seller in the store worked according to the instructions that came with the fan
At least that's how it seemed - did he make a mistake in the installation?

Socket 1700 does require proper a proper mounting adapter.

Notice on that list that it is mentioned on many of the coolers.

"NM-i17xx................................"

Notice that it is NOT mentioned for your cooler, which would imply that the proper adapter is already included or otherwise not needed. I don't know the gory details of what the U12A looks like out of the box.

Possibilities are:

1; Noctua web site is flat out wrong; extremely unlikely.

2; Something unusual in your situation that is not revealed in your pictures.

3; RAM height issue; that is a factor in some situations. Many Noctua coolers are designed so as to NOT overhang ram slots. I do NOT know the details of the U12A, but I'd certainly drill into the specs at Noctua. It should be mentioned. I have not looked.

In some cases on some coolers with some RAM, a fan has to be fudged up a bit to clear tall RAM.

Maybe that's what has happened in your situation. I can't tell from the pix.

Maybe your builder did all he could given your chosen RAM; maybe he has no talent and is a fool. I can't tell from the pix.

I just photographed it from all angles - as mush as possible - the fans are big and it makes it difficult

I just searched for 1 minute.

I was led to believe that RAM you have chosen is 49 MM tall.

https://www.teamgroupinc.com/en/product/delta-rgb-ddr4

That's taller than most and may prevent standard installation. You be the judge. Either the cooler fan will clear the RAM in standard positioning or it won't.

If it won't, maybe the builder did what he could for you.

I have NO idea.

The builder just to check - took another cheaper stick and had the same problem with it too.
Can anyone else shed light on this incident? I want to get back to him tomorrow with answers

Plenty of RAM is under 30 inches tall; that would give you nearly an inch more clearance.

RAM cost is not a factor. Dimensions are a factor.

Don't know if you drilled into Noctua site re details of U12A clearance issues.

Don't know why you chose that RAM.

Can't put my own eyeballs on your situation, so who knows.

You could certainly try varying the RAM slots to escape any clearance issues. Don't know how well that would go over.

13900 is a hot plate. Why are you going air over water/AIO in the first place?

If you do a quick search you'll see the 13900 will definitely hit 100c on air (looked at your cooler specifically) with ease under any considerable load.

 

[ilukey77]

yeah your ram is the problem BUT the heat pipes are the key not the fin stack cooling so much if that makes sense so ..

for reference i tried on my 7800x3d a deep cool AK500 digital using the Noctua NH-U12A fans ( push pull )
with 5 per side heat pipes ( much bigger fin stack than the Noctua ) VS the actual Noctua NH-U12A chromax with same fans with the 7 heat pipe per side the Noctua won hands down !!

My advice is suck it and see its not going to blow you cpu your still using both fans unless you cant put the TG panel on but by your pics that doesnt seem to be a issue ..

really you have 3 options here
1. change your ram
2. change the cooler ( I would go a 360mm aio for the 13900k )
3. ( not really a option just a idea ) use a thermal right LGA1700 bracket like this which is know to help keep the LGA1700 cpu's cooler by reducing Known flex with the cpu in the socket !!

ThermalRight LGA17XX-BCF 13TH Generation CPU Hodler Correction Fixed LGA1700 Buckle Anti-pressure Bending Bracket Pressure Plate​

ali express dirt cheap pay with pay pal !!

All that said the Noctua NH-U12S is like a smaller D15 but even with the D15 the 13900k can be a challenge to cool !!
But unless your stressing the cpu like all the time under gaming it will most likely never throttle !!

Thank you very much, I'm leaning towards replacing the memory
My memory now is: Team Group Delta RGB DDR5 32GB 7600 (2 x 16GB) FF3D532G7600HC36DDC01
I want to stay on 7600 and I have 2 options which are QVL with my motherboard (GIGABYTE Z790 AORUS Master):
1. G.Skill F5-7600J3646G16GX2-TZ5RK
2. Corsair (ver. 5.43.01) CMT32GX5M2X7600C36
Do you have a website that shows the sizes? Google doesn't really help me here

It's a little too late for me to replace the fan - if that was an option I would definitely consider it

Right now i'm with: Team Group Delta RGB DDR5 32GB 7600 (2 x 16GB) FF3D532G7600HC36DDC01

I'm thinking of switching to:

If the two 7600 options are also the same sizes as my current one - it's important for me to know now so that I simply don't waste time on this idea

modern AIO's are really decent ive been using my NZXT x63 across a few builds on and off now with no issues..
the likely hood of the pump to just stop is unlikely in actual fact your more likely to upgrade your CPU before the AIO dies ..
BUT
I get the safety of a air cooler ..

the Gskill z5 RGB cl30 6000 32gb i use ( while expo and sweet spot for AMD ) fits fine on my rog crosshair x670e gene using the Noctua NH-U12A with push pull config no issues with ram clearance ..

So im almost 100% sure that the Gkill z5 rgb will be fine to use with that cooler regardless of mobo !!

i think you will find the team group your using with it weird shape is the issue

dominator ram may be a issue the vengence stuff is much lower but no rgb..

G.Skill MESG-F5-7600-3646-16 Trident Z5 RGB 32GB 7600MHz DDR5 RAM Memory​

That will fit no issues as its the same as what i use ( just for AMD ) lower latency and speed !!

To clarify the fan will sit on or just slightly off that ram as there is 45mm to 46mm clearance on the cooler with the rgb and heat sinks the ram measures at about 46mm so it will be tight but the fan will not sit up like it does now 100% sure

I don't care about rgb
Do you have any site information that proves it is smaller? I will lose health if I buy this and it is the same size

i updated the post with the ram size i can assure you it will work fine !!

How tall are the memory modules?
The height of the memory modules are listed as follows:

DDR5 Memory Series
Ripjaws S5: 33mm (1.30in)
Flare X5: 33mm (1.30in)
Trident Z5: 44mm (1.73in)
Trident Z5 RGB: 44mm (1.73in)
Trident Z5 Neo: 44mm (1.73in)
Trident Z5 Neo RGB: 44mm (1.73in)
Zeta R5: 31.2mm (1.2in)
taken from Gskill ( i just stuck a ruler in my system and measured about 45mm to 46mm ram height then measured the NH-U12A cooler from coldplate to fin stack and roughly go 45 to 46mm so it will fit 100% )

So just to understand you: if I don't care about RGB - The lowest in size for sure is: Corsair CMT32GX5M2X7600C36
Over the G.Skill F5-7600J3646G16GX2-TZ5RK?

I really don't care about RGB - I just want to smaller one

NO G skill is the smaller stuff check my previous post with the sizes !!

i cannot find the sizing chart on the corsair ram but from builds ive seen on youtube its quite high ..

BUT i know the Gskill stuff and the Noctua cooler because i have both of them and it fits no issues !!

the fan may sit up like a 1or 2mm higher but its not going to sit as high as the current ram !!

your current ram is 49mm high from website spec sheet the Gskill z5 is 44mm per website spec sheet i measured 46mm but it was a rough measurement ..

 

[ilukey77]

the other option is have you tryed mounting the cooler the other way around so that the smaller bracket is closer to the vrm and the longer bracket is closer to the ram basically pushing the cooler closer to the VRM heat sink not the ram !!

!! Actually now im looking at the cooler i have flip it 360 first before buying ram !!

its quite a big heat sink there more than big enough for the LGA1700 SOCKET

Not following the logic at all. You can swap and put more money towards different RAM hoping the cooler which is the problem in the first place will fit but not just replace the cooler with something that will definitely work?

I really don't get why you are obsessing on the cooler and magically obtain compatibility rather than just swap the damn thing out.

I have no advice beyond what I mentioned. Good luck, let us know how it goes.

Frectal Torrent is a case whose whole principle is air cooling
To do an aio on this case is to miss the point of the case itself - and almost 100 percent to damage the cooling of the gpu
The king of the case is the 4090 gpu - this case with the "stock" fans cools the video card very nicely and you will be surprised that it also cools the processor in a stunning way when the processor is on a fan cooling

Thanks for the help - a few questions:
I don't live in the US or Europe and to replace the ram I'll stand to lose about $33-40.
That's the situation I'm in now. I'm willing to lose it if the fan sits properly - perfectly 100%.

In the measurement I made now, the fan "comes out" 15 millimeters. (But they don't sit close together as you can see in the pictures - I guess if they sat close together the number would be smaller)
Are you saying that if I switch to Gskill it will "come out" 1 or 2 millimeters?
It is important that I understand because you wrote: "your current ram is 49mm high from website spec sheet the Gskill z5 is 44mm per website spec sheet i measured 46mm"

Explain to me how I will end up with 1 or 2 millimeters if the whole difference between them is 5 millimeters according to their website and according to your measurement the difference is only 3 - Did I get something wrong?
