Noctua NH-D15 with NM-AMB12 compatibility issue with MSI X670E ACE

Paizuri Amalgamation · Dec 2, 2023

Title says all.

The offset mounting bars brings the already massive and already close enough to the GPU aircooler even closer to the GPU that you will scrape both the cooler and GPU trying to fit in one or the other, which I don't want happening and assuming others won't either.

Unfortunate but it is what it is. I don't think I will be missing that potential 1-3c reduction on the CPU much.

You need the NH-D15S

Peerless Assassin, Phantom Spirit, maybe Frost Spirit.

Depends on CPU choice, workload, ambient temperatures, and noise target. In what I've looked at a 7950X tends to hit 160 A TDC before 95 °C but not by enough Ta ≥ 30 °C wouldn't frequently be temperature limited.

What Counterclockwise said. Both cool as good, maybe better than NH-D15. There has been some issues with fan bearing quality control, but coolers at top tier.

Isn't that just an NH-D15 with one fan?

Unlike the NH-D15, the NH-D15S is offset base. Still costs 2-2.5x the alternatives mentioned for probably worse performance, though.

What Counterclockwise said.
The NH-D15S is an asymmetrical based ]single fan version of NH-D15. NH-D15S base is offset 8mm so fins reach 67mm toward PCIe sockets and 83mm other way. NH-D15 base is symmetrical with finpacks reaching 75mm both sides of center. End result is NH-D15S has 8mm more room between PCIe and cooler fins. NH-D15 and NH-D15S 150mm width being offset means sometimes bottom fin will not clear all components on some motherboards.

NH-D15 and NH-D15S are 135x150x160mm (LxWxH w/o fans) NH-D15S 67mm of fin toward PCIe
Phantom Spirit 120 series are 110x125x154mm 55mm of fin toward PCIe
Peerless Assassin 120 are 110x125x155mm 55mm of fin toward PCIe
Frost Spirit 140 are 121x140x158mm 57mm of fin toward PCIe

All cool within a few degrees of each other.

Except it doesn't cost as much if one sells the NH-D15, to recoup some of the costs

all 3 of those Thermalrights are also offset, and a good choice as well. Thermalright doesn't have offset brackets yet, but they might be getting announced on CES in January now

There's also the new Noctua NH-D15 G2 coming Q2 next year that's also offset. And u can keep using your Noctua offsets.

Selling NH-D15 to recoup some of cost does not change how much a new cooler costs.
If NH-D15 is sold after installing one of the Thermalright coolers the new Thermalright coolers would be free.

If Noctua doesn't delay it again. Like they have for the last eight years.

Also, to be somewhat pedantic, while the prototypes shown at Computex were offset and it'd be weird if any eventual production wasn't offset, neither of those is actually a guarantee.

Thats what I have over my 7950x3d cpu. At the time I built the rig wasn't aware of the mounting plates they have available but my temps with cinabench hit 84 degrees max load with push pull triple fan configuration with the stock fan in the middle with two quality cfm air pushing low noise fans on the ends and I had just enough room to place two Gskill Trident Neo DDR5 6000 mhz modules. If it wasn't for AMDs ridiculous out of the box hot temps for this cpu I know I would be getting better temps on any other cpu!

Also when I first mounted the heatsink it got in the way of seating the graphics card but turns out I had it mounted backwards. The only other issue you might have though with this heatsink is depending on the case if you side mount your gpu with a riser cable the cooler might get in the way. Probably standard low profile gpu's be fine but any other gpu be an issue. In anycase it has my vote for being a quality heatsink I highly recommend!
