Enlarged contact surface
At 70x56mm, the heatsink’s copper contact surface is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of Intel’s LGA4677/LGA4710-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.

Dual NF-A15 140mm premium fans
The NH-U14S DX-4677 is equipped with two of Noctua’s award-winning NF-A15 140mm fans. This powerful push/pull dual fan configuration allows it to achieve an unrivalled level of quiet cooling performance and makes it the first choice for workstations that require the best possible cooler, period.

Pre-applied NT-H1 thermal compound
Noctua’s much-acclaimed NT-H1 is a pro-grade TIM solution that provides minimum thermal resistance and outstanding long-term stability. Having the paste pre-applied to the heatsink base ensures optimal bond-line thickness and saves precious time in installation. Ideal for system integrators!

Customised for LGA4677 and LGA4710
The Noctua DX-4677 line coolers are dedicated, customised solutions for Intel’s professional socket E1 (LGA4677-1) and socket E2 (LGA4710-2) platforms, which makes them an ideal fit for quiet, high-performance servers and workstations utilising Xeon processors.
