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-A12x25 PWM fans
The NH-U12S DX-4677 is equipped with two of Noctua’s award-winning, next-generation NF-A12x25 120mm fans. This exquisite, state-of-the art push/pull dual fan configuration allows it to achieve a remarkable level of quiet cooling performance despite its relatively compact size.

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.
