Dedicated AMD sTRX4/TR4/SP3 cooler

The NH-U14S TR4-SP3 is a single-tower air cooler built specifically for AMD Threadripper and Epyc processors on sTRX4, TR4 and SP3 sockets. Its customised larger base matches the socket's contact area and cannot be used on any other platform. The 140mm NF-A15 PWM fan provides automatic speed control for quiet operation. This cooler targets builders assembling high-end workstation or enthusiast systems using supported Threadripper or Epyc CPUs.

SecuFirm2 mounting and NT-H1 compound included

The package supplies the SecuFirm2 mounting hardware designed exclusively for the sTRX4/TR4/SP3 socket, removing the need for separate bracket kits. A tube of Noctua NT-H1 thermal compound is also provided for immediate installation. Because the base is tailored to these sockets, standard Noctua mounting kits are not compatible and cannot be used as alternatives. The bundled accessories therefore define the exact platform support and simplify the build process.

Single-tower design with premium 140mm fan

The cooler uses a single-tower heatsink topped by the NF-A15 140mm PWM fan, a combination recognised for high thermal capacity and low noise. Its dimensions suit typical workstation chassis while clearing most memory slots on TR4/SP3 motherboards. The six-year manufacturer warranty reflects the build quality expected from Noctua's premium line. Daily use benefits from quiet PWM operation and a robust mounting system that maintains even pressure across the large CPU heatspreader.

Questions about this item

Will the NF-A15 fan or NT-H1 paste need periodic replacement on this cooler?

The NF-A15 PWM fan is built for long-term operation without scheduled replacement; NT-H1 thermal compound remains effective for years and only needs re-application if the cooler is removed.

What thermal limit appears first during continuous load on a Threadripper 3990X?

The single-tower 140 mm design reaches its heat-dissipation ceiling before the fan hits maximum speed, so sustained all-core workloads are limited by the cooler's fin-stack capacity.

How much noise and heat does the NF-A15 PWM fan produce in all-day operation?

The NF-A15 runs quietly at low PWM duty cycles and only becomes audible near full speed; heat output matches the CPU's power draw since the cooler adds no active heating.
