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 (E1) and LGA4710 (E2) 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-speed 2500rpm version), it combines strong performance with excellent compatibility for 4U systems and other space-restricted applications. The NH-D9’s direction of airflow is parallel to the long axis of the LGA4677/LGA4710 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 or LGA4710 based Xeon workstations and servers.
