The Noctua NH-U9 DX-4677 heatsink features a larger contact area, tailor-made for LGA4677 platforms. Based on the proven NH-U9 heatsink and equipped with two Noctua NF-A9 92 mm fans, it combines high performance with excellent compatibility for 4U systems.
The airflow direction of the NH-U9 DX-4677 is perpendicular to the long axis of the LGA4677 socket, making it ideal for systems where the exhaust fans are in that direction. Complemented by the SecuFirm2 professional mounting system and pre-applied NT-H1 thermal compound, the NH-U9 DX-4677 forms a package for quietly and efficiently cooling LGA4677-based Xeon workstations and servers.
