Noctua NH-D9 DX-3647 4U, Premium CPU Cooler for Intel Xeon LGA3647 (Brown)

Brand: Noctua

Noctua NH-D9 DX-3647 4U Premium CPU Cooler for Intel Xeon LGA3647 (Brown)
Product Description

Noctua’s DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The NH-D9 DX-3647 4U features a larger custom-designed contact surface and supports both square and narrow type LGA3647 platforms. Based on the proven 92mm size NH-D9L heatsink and equipped with two of Noctua’s renowned PWM controlled NF-A9 92mm fans (high-efficiency 2500rpm version) it combines strong performance with excellent compatibility for 4U systems and other space-restricted applications. Topped off with the professional SecuFirm2 mounting system and pre-applied NT-H1 thermal compound the NH-D9 DX-3647 4U forms a complete premium quality package for quietly cooling LGA3647 based Xeon workstations and servers.

^{DX series for Intel Xeon}

First introduced in 2008 Noctua’s DX line CPU coolers have become a standard choice when it comes to quiet premium grade air cooling solutions for Intel Xeon processors. Thanks to their superior acoustic efficiency they are ideal for workstations and servers that run in noise sensitive environments (e.g. audio/video production content creation engineering etc.).

^{Enlarged Contact Surface for LGA3647}

At 70x56mm the heatsink’s copper contact surface is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of Intel’s LGA3647-based processors this customised design allows for an optimal heat flow from the CPU over the base to the heatpipes and on to the cooling fins making them an ideal fit for both Skylake-SP based Xeon Scalable CPUs (Platinum Gold Silver or Bronze Purley series) and Xeon-Phi processors (code names Knight’s Landing or Knight’s Mill).

^{Dual NF-A9 PWM fans}

The NH-D9 DX-3647 4U is equipped with two of Noctua’s award-winning NF-A9 92mm fans in their high-speed 2500rpm HS-PWM variant. This push/pull dual fan configuration makes it possible to achieve a level of cooling performance that is remarkable for such a compact cooler and comes close to the bigger NH-U12S DX-3647.

^{Pre-applied thermal compound}

Having Noctua’s much-acclaimed NT-H1 paste pre-applied to the heatsink ensures optimal bond-line thickness and saves time in installation. Ideal for system integrators!
