Noctua NH-D9 DX-4677 4U, Premium CPU Cooler for Intel Xeon LGA4677 & LGA4710 (Brown)

Noctuas 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 Noctuas 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-D9s direction of airflow is parallel to the long axis of the LGA4677 socket, so it is ideal for builds where the hot air is exhausted this way. 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.

At 70x56mm, the heatsinks copper contact surface is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of Intels 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.
