NH-D9 DX-4189 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-4189 4U features a larger, custom-designed contact surface for LGA4189 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-D9’s direction of airflow is parallel to the long axis of the LGA4189 socket, so it is ideal for server builds where the cooler’s fans should work in tandem with the airflow inside the chassis, or for workstation builds where this orientation is required for having the cooler exhaust towards the top of the case. Topped off with the professional SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound, the NH-D9 DX-4189 4U forms a complete premium quality package for quietly cooling LGA4189 based Xeon workstations and servers
