Noctua DX-3647 coolers keep Xeon Scalable chips cool and quiet

Noctua is known for quiet and effective cooling solutions typically topped off by uniquely-hued fans. The company's offerings carry premium price tags, but so do the Xeon Scalable and Xeon Phi processors that Noctua's LGA 3647 coolers are designed for. The DX-3647 family of coolers is designed for use exclusively with Intel's jumbo socket and has members with pairs of 92-mm or 120-mm fans, or a single 140-mm rotating air mover. All three new models have copper bases and heat pipes along with aluminum fin stacks.

Noctua NH-D9 DX-3647

The NH-D9 DX-3647 is the smallest of the bunch and uses a pair of fin arrays interleaved with two of 92-mm Noctua's NF-A9 PWM fans. Those spinners have a maximum rotational speed of 2500 RPM. The D9 is the the company's only offering for server builders using 4U enclosures. The key number among the D9's specifications is probably its 5.3″ (13.4 cm) height.

Noctua NH-U12S DX-3647

Noctua's NH-U12S DX-3647 uses a pair of NF-A12x25 120-mm fans as the bread around a single aluminum fin array. The U12S is the heaviest of the bunch at just under 36 oz (1018 g) with its fans attached. The unit's 6.2″ (15.8 cm) height means it isn't going to fit in a 4U server rack without a hot rod-style hole cut in the lid.

Noctua NH-D14S DX-3647

The NH-U14S DX-3647 is the biggest of the bunch at 6.5″ (16.5 cm). Its 34-oz weight with its fan (957 g) is a little lower than that of the U12S, though. The cooler has mounting spots for both 120-mm and 140-mm fans for buyers who don't want to use the included NF-A15 spinner.

The Noctua NH-D9 DX-3647 and NH-U14S DX-3647 coolers come in at a cool $90 each at Amazon. Getting the middle child NH-U12S DX-3647 will require trading away a whole portrait of Benjamin Franklin. The company says all three LGA 3647 models will fit both the square and the narrow versions of Intel's plus-sized server socket. The manufacturer backs the coolers with a six-year warranty.

    Noctua, my anti-RGBLED hero.

    Wow, Socket 2066 is already a pretty tiny niche.

    Consumer coolers for enterprise level Xeons (and 28-core marketing stunts that may or may not actually make it to market in realistic quantities) is a tiny niche of [i<]that[/i<] tiny niche.

      It isn’t THAT tiny – Mindfactory numbers put it at about 5-10% of revenue, depending on the month.
      But yeah, slice seems too tiny for 3647 and 2066 to coexist. I believe 3647 will replace 2066 as the HEDT. 2066 seems pretty pointless these days. The only scenario where it is relevant is “I want higher MT performance than i7 8700k or extra PCIe/memory, better ST than offered by TR and I don’t care about perf/$ all that much”.
      I believe this is a pretty small niche that is getting smaller when Intel releases 8C desktop chips and TR2 hits.
      3647 might be pretty irrelevant from the point of buying one due to cost, but at least it would offer marketing opportunities and bragging rights like the 16C and 18C do now (and won’t when TR gets to 32C).

        5-10% of revenue is misleading, since the median selling price of a socket 1151 chip is €170 whilst the median selling price of a socket 2066 chip is €1395

        In other words, based on those Mindfactory numbers, socket 1151 outsells 2066 by a factor of about 125:1.

          Still, it sets Noctua in my mind as one of the few go-to high-end cooler companies.

          Revenue may be less important than reputation. There’s literally no one else who covers the high end in a similar way.

    This is pretty much another confirmation that LGA3647 is going to get the HEDT treatment.

      Intel has to respond in some way to AMD 32/64 CPU.

      As Newt stated so eloquently.

      Wonder how neutered it will be. snip snip snip

      The current 2066 [i<]subtracted[/i<] 4 cores from the densest skus and dropped ECC from 2011v3. That was no angel either, they managed to lock 1P xeons in the middle of the life cycle and add pointless segmentation of pcie lanes coming from 2011.

    They’re just so pretty. I love that their color scheme hasn’t changed in forever.

      • JustAnEngineer

      They’ve introduced new colors in the past few years.

      My Noctua NH-D14 could even keep my FX-8320 (clocked at 4.7-4.8Ghz) running cool, but DAMN the fins would cut the cr@p out of my fingers when I had to fiddle with it or anything around it especially memory modules. AIO coolers are a little more “finger friendly”.

      Yes, love to show off that no-nonsense “I just care that it’s cooling”-look,

      oh wait…
