The NH-D9 TR5-SP6 4U is a 92mm size premium quality quiet CPU cooler for workstations and servers based on AMD Threadripper and Epyc processors that utilise TR5/SP6 sockets (sTRX5/sWRX9). Built on the proven basis of the DX model with its dual tower heatsink and full-cover contact surface, the TR5-SP6 revision employs two of Noctua’s award-wi... morenning, PWM controlled NF-A9 PWM 92mm fans in their higher speed variant in order to achieve strong performance and superb acoustics. The NH-D9’s direction of airflow is parallel to the long axis of the socket, so it is ideal for builds where the hot air is exhausted this way. Topped off with the pre-applied NT-H2 thermal compound as well as the professional SecuFirm2™ mounting system for TR5/SP6 that has been updated to meet the platform’s increased pressure specifications, the NH-D9 TR5-SP6 4U forms a complete premium quality package for quietly cooling TR5-based Threadripper workstations and SP6-based Epyc servers in 4U cases. Please note that the NH-D9 TR5-SP6 4U is a dedicated version for AMD TR5/SP6 sockets (sTRX5/sWRX9). Due to its customised larger base, it cannot be used on smaller sockets and is incompatible with Noctua’s mounting kits for these sockets
