Noctua’s DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The NH-U12S DX-3647 features a larger, custom-designed contact surface and supports both square and narrow type LGA3647 platforms. Based on the proven, 120mm size NH-U12S heatsink and equipped with two of Noctua’s award-winning, PWM controlled NF-A12x25 120mm fans, it provides an excellent balance of performance, compatibility and quietness of operation. Topped off with the professional SecuFirm2™ mounting system and pre-applied NT-H1 thermal compound, the NH-U12S DX-3647 forms a complete premium quality package for quietly cooling LGA3647 based Xeon workstations and servers.
Caution
Please note that the NH-U12S DX-3647 is a dedicated version for the Intel LGA3647. Due to its customised larger base, it cannot be used on any other sockets and is incompatible with Noctua’s standard mounting kits.
