Noctua NH-D9 DX-4677 4U CPU Cooler For Xeon Socket 4677

Manufacture # Noctua | Model # NH-D9-DX-4677-4U

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-4677 4U features a larger, custom-designed contact surface for LGA4677 platforms. Based on the proven, 92mm size NH-D9L heatsink and equipped with two of Noctua’s award-winning, 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. The NH-U9’s direction of airflow is perpendicular to the long axis of the LGA4677 socket, so it is ideal for systems where the exhaust fans of the chassis are in this direction. For systems that require the airflow to go parallel to the long axis of the socket, please choose the NH-D9 DX-4677 4U. Topped off with the professional SecuFirm2 mounting system and pre-applied NT-H1 thermal compound, the NH-D9 DX-4677 4U forms a complete premium quality package for quietly cooling LGA4677 based Xeon workstations and servers.

Features:

• 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.).
• The new DX-4677 line coolers are dedicated, customised solutions for Intel’s professional LGA4677 platform, which makes them an ideal fit for both 4th generation Xeon Scalable CPUs (Platinum, Gold, Silver or Bronze) and w9, w7, w5 or w3 series Xeon processors for workstations.
• 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 LGA4677-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.
• LGA4677 processors require plastic CPU carrier frames for installation, which are included with retail boxed CPUs and available separately via Intel sales partners for tray CPUs. The SecuFirm2 mounting for LGA4677 is compatible with all types of carriers (E1A, E1B, E1C).
• Thanks to its compact footprint (95x95mm with center fan only, second fan can be installed on either side depending on available space) and a total height of only 134mm, the NH-D9 DX-4677 4U provides excellent PCIe compatibility and is small enough to fit most 4U size rack-mount enclosures.
• The NH-D9 DX-4677 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-4677.
