Planning on buying Noctua DH15 with 3950x.. what sort of blocked stuff due monster heatsink can I expect?

[Windows95]

I plan on getting this:

 

Fraktal define R6

Asus Aorus Pro (no wifi)

Noctua NH 15

RAM: https://www.gskill.com/product/165/326/1562840211/F4-3600C16D-32GTZNC-Overview

 

Will I have problems in terms of the heatsink blocking the ram, or something blocking features of the Aorus Pro (PCI lanes??) or not fitting on the define R6?

 

Im asking because Noctua went as far as releasing another edition (the DH15s) because it was too big for some rams.

 

Im just paranoid im going to spend all this money, then find out shit doesnt fit.

Anyone actually owns this combo by any chance?

The neo is tall, but it's not toooo tall.  And the D15s is more about fitting a GPU in the first slot, some mobos make it block that first PCIe x16

and how do I know that? fucking hell

I'm using the U12A on a 3950X as of this weekend. It's doing extremely well and you won't have clearance issues.

but i will have to raise the second fan making it look like a joke:

 

 

like i said im gonna use a windowed case so not that concerned aesthetics wise, however... doesnt that damage the air cooling thing and make the hair go all over the place? it shoul be going in a straight direction, wouldnt that push warm air around the case?

That was not a U12A.... this is.

AFAIK the U12A is within margin of error from a D15 so...

Then buy one m8y.  If there is one, and you decide that having a 10mm offset is the end of the world, just don't use the extra fan.

[freeagent]

With a D14/15 you can expect to not be able to get to your ram once you install the fan.

Then what's stopping you? You can always move fan to other side if looking cool is what you are after.

my case will not even have a window

 

im just concerned about having a fan sitting halfway on the heatsink will just be pushing warm air all over the case tus making it worse

the offset making air movement weird is what concerns me

 

we need an engineneer and draw air path physics on what happens if you cut the trajectory with that offset

With that logic, it would be better. If front fan is pushing warm air over the heatsink, that is. I'm fairly certain that if Noctua felt like having fan like that would cause issue, they would have used 120mm fan instead. Besides, D15S comes with only single middle fan and difference in performance is minimal to D15.

The NH-D15S is mainly offset to not block the top pcie slot. What increases the ram compatibility is the lack of a front fan. For ram, you can achieve a similar result by running the NH-D15 without the front fan. 

The cooler overhangs the ram so you won't get to see much of the sticks but it fits fine. Here's an example: https://pcpartpicker.com/b/hWyXsY

Please be more specific for the motherboard model. You can see any potential motherboard compatibility issues on the cooler website: https://noctua.at/en/products/cpu-cooler-retail/nh-d15/comp

It's not a huge difference and the center fan does most of the work.

I dont want to compromise with d15s cause its a 3950x after all... any extra cº cooled down is good

 

the mobo is an aorus pro, ram is gskill tridentz neo

There are 4 atx am4 motherboards that have Aorus Pro in the name. You can check the motherboard compatibility list I linked above.

Yep, the green check mark means that there should be no compatibility issues with the motherboard.

At that point just don't get a D15. If you want the lowest possible temps go liquid or just crank the fans to 100%.  The temp difference between the offset turbulence (if there even is any) or running a single fan will all be in margin of error anyway. Hell, if you're that bothered just get some low profile ram and run a D15 as it is.

 

FYI, I've got a 3700x with a D15s (with 2 fans and a black chromax kit) + LP RAM, no exhaust fan and all in an NZXT H200.  At full synthetic load on CPU + GPU with PTO enabled and GPU overclock I get 82C @ 58% fan speed after 2 hours.

I have a noctua NH-D15 and know it works OK with corsiar LP 'low profile' ram.   I had plenty of room.    It would works with some taller ram as well.

Says who? Planning to double the case as a windtunnel to test aircraft design?

Ultimately there will be tons of turbulence in a case anyway due to:

 

1. assymetry in case vent openings

2. Fans not being in absolute center of case

3. Fans not being on center of a single axis befween intake and exhaust openings

4. The mobo fan spitting outward, cpu fan spitting rearward and gpu fans suckingupward and spitting outward againts mobo and opposite side panel

5. Components and cables

 

This will heat up any box allround anyway without throughput of airflow aside of the cpu coolers static p flow to vent the air between the coolers plates.

 

This is why (for positive pressure setup) there are usually 2 or more intake casefans and N - 1 (N being intake fan count) exhaust fans.

 

Its a 5 step thing going on:

1. Die/IHS transfer heat to heatsink pipes

2. Heatpipes distribute heat to the plates/sheets.

3. Heatsink plates transfer heat to airpockets between the sinks sheets

4. Heatsink fans move heat from the sinks airpockets between the sheets to the case internal air volume.

5.The case fans move the heated case internal air volume out while sucking cold(er) air in

Thats what heatsink fans do in general, as intended, see the above. If they wouldnt theyd just serve no purpose.

ive spoken to owners of 3900 with d15 and they report lower temps as far as i can remember

Don't buy that ram then. The cooler is gonna cover it anyway.

Yeah but that's just the H200 with limited airflow.  The point I was making was even though my case is less than ideal, at full system load and <60% fan speed I'm still getting decent temps.
