## Long description

The Noctua NH-U12S DX-4677 is a premium air cooler designed specifically for Intel LGA4677 platforms. Based on Noctua’s proven 120mm NH-U12S heatsink, it features an enlarged 70x56mm copper contact surface, five heatpipes and a dual-fan configuration with two NF-A12x25 120mm PWM fans. The package includes the SecuFirm2™ mounting system with Intel-compliant parts, a pre-applied NT-H1 thermal compound and a Torx® T30 mounting tool for straightforward installation in Xeon workstations and servers.
Advantages
The enlarged contact surface is tailored to the large integrated heat spreaders of LGA4677 CPUs, improving heat transfer from the CPU to the heatpipes and fins. Two next-generation NF-A12x25 PWM fans in a push/pull setup deliver a balance of high cooling capacity and low noise, while PWM support and the included y-cable allow automatic speed control from a single motherboard header. The pre-applied NT-H1 thermal compound ensures optimal bond-line thickness and faster installation. SecuFirm2™ mounting using standard Intel parts ensures compatibility with E1A, E1B and E1C carrier frames and a familiar installation procedure.
Suitable for
Cooling Intel LGA4677 Xeon Scalable CPUs in servers and workstations
Quiet workstation environments (audio/video production, content creation, engineering)
Systems requiring reliable long-term operation and easy installation by system integrators

How to use
Fit the cooler using the included SecuFirm2™ mounting system and the Torx® T30 tool, following Intel LGA4677 installation guidelines and using the appropriate carrier frame (E1A, E1B or E1C). Ensure the pre-applied NT-H1 thermal compound remains intact on the contact surface until mounting. Connect both NF-A12x25 PWM fans to the supplied y-cable and attach the cable to a single motherboard fan header to enable automatic speed control. Verify clearance in your chassis and around the CPU socket before final assembly.
Usage recommendations
Install the cooler on a clean CPU surface and verify compatibility with your carrier frame type (E1A/E1B/E1C). Use the motherboard fan control (PWM) to allow automatic fan speed regulation and maintain regular dust cleaning intervals to preserve cooling performance and quiet operation.
