Noctua Releases Three CPU Coolers For Intel’s LGA3647 Xeon Platform

When we met up with our friends at Noctua during Computex a couple of weeks ago, it impressed me a bit to see a couple of CPU coolers destined for Intel’s latest Xeon platform, based around the LGA3647 socket. Clearly, there’s some demand, because beyond these coolers, I saw the platform promoted pretty heavily throughout the event. If the 18-core i9-7980XE desktop CPU isn’t sufficient enough, or you simply require ECC memory (or other Xeon perks), Noctua can help you secure an attractive, and effective cooler for your new build.

The most modestly sized of the three coolers here is the NH-U12S DX-3647, which uses dual 120mm fans. Then there’s the NH-U14S DX-3647, which forgoes a second fan in lieu of a single 140mm (a second fan could of course be added after-the-fact). The biggest of the three coolers is seen in the shots below; the NH-D9 DX-3647 is a dual-tower style cooler with two 92mm fans. The name of the game here is effective cooling with as little noise as possible.

Since overclocking is a non-option with Xeon, these coolers don’t need to boast the ability to cool well under extra stress. That could of course change if Intel decides to make its 28-core desktop chip a reality, but chances are that chip would not use the same socket as this – and even if it does, Intel used phase-change cooling to overclock to 5GHz, so air doesn’t seem like the route you’d want to take anyway.

It’s important to note, even if it’s seemingly obvious, that any one of these CPU coolers is exclusive to this platform. The size of the base makes them unmountable on other platforms. Here’s the mounting kit you can expect to see in the box:

It might be an enterprise-type product, but that doesn’t mean Noctua doesn’t know how to spice things up. Check out the thermal paste application on these coolers:

Almost surprisingly, these coolers are available right now, over at Amazon. The U12S, with its double fans, is priced at $100, whereas the other two are priced at the same $90.
