Noctuas DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The NH-U12S DX-4677 features a larger, custom-designed contact surface for LGA4677 platforms. Based on the proven, 120mm size NH-U12S heatsink and equipped with two of Noctuas 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-4677 forms a complete premium quality package for quietly cooling LGA4677 based Xeon workstations and servers.
At 70x56mm, the heatsinks copper contact surface is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of Intels LGA4677-based processors, this customised design allows for an optimal heat flow from the CPU over the base to the heatpipes and on to the cooling fins.
