Continuing the legacy of Noctua’s classic NH-U-series, which has received more than a thousand awards and recommendations from international hardware websites and magazines, the NH-U12S has become a benchmark for high-end 140mm single tower coolers. The TR4-SP3 version is a tailored custom model for AMD’s TR4/SP3 platform (Ryzen Threadripper / Epyc) and features a larger contact surface as well as the latest SecuFirm2 mounting system for socket TR4/SP3. Topped off with the renowned quiet NF-A15 PWM 140mm fan, Noctua’s proven NT-H1 thermal compound and a full 6-year manufacturers warranty, the NH-U12S TR4-SP3 forms a complete premium-quality solution that combines maximum performance and superb acoustics for enthusiast-grade TR4/SP3 systems. Award-winning NH-U12S cooler Tens of thousands of enthusiast users all over the world swear by the NH-U12S quality and performance. Recommended by more than 200 international hardware websites and magazines, it is renowned as being one of the best 120mm coolers on the market. Tailored custom version for TR4/SP3 (Ryzen Threadripper / Epyc) At 70x56mm, the copper contact surface of the TR4-SP3 version is more than double the size of the standard model. Tailored to fit the enormous integrated heat-spreaders (IHS) of AMD’s TR4/SP3-based processors, this customised design allows for an optimal heat flow from the CPU over the base to the heatpipes and onto the cooling fins. 120mm size for excellent performance and compatibility With five heatpipes and the powerful NF-F12 120mm fan, the NH-U12S achieves outstanding cooling performance while maintaining excellent compatibility: At 158mm height and 125mm width, it is short enough to fit most modern tower cases and stays clear of the top PCIe slot on most motherboards. NF-F12 120mm Focused Flow fan Recommended by more than 150 hardware publications and thousands of enthusiasts world-wide, the Noctua’s premium quality NF-F12 Focused Flow™ 120mm fan is renowned to combine superb static pressure, excellent heatsink performance and surprising quietness of operation. PWM support and Low-Noise Adaptor The NF-F12 120mm fan supplied with the NH-U12S supports PWM for convenient automatic speed control through the mainboard. In addition, the maximum fan speed can be reduced from 1500 to 1200rpm using the supplied Low-Noise Adaptor for even quieter operation. Anti-vibration pads and fan-clips for second NF-F12 (optional) For users who want to achieve even better performance by adding a second, optional NF-F12 fan to create a push/pull setup, the NH-U12S includes fan clips and an extra set of custom-designed anti-vibration pads that allow to off-set the rear fan by 5mm to improve acoustics in dual-fan mode. SecuFirm2 mounting system for sTRX4/TR4/SP3 Noctua’s SecuFirm2 mounting systems have become synonymous with quality, safety and ease of use. The TR4-SP3 variant has been completely custom-designed for the new socket and is particularly easy to install: Put on the heatsink, fix the four spring-loaded screws and you’re done! Offset mounting options for better PCIe clearance In order to assure optimal compatibility with SLI and CrossFire multi-GPU setups, the SecuFirm2 mounting for TR4/SP3 makes it possible to offset the cooler by 3 or 6mm towards the upper edge of the motherboard, thereby increasing clearance of the top PCIe slot. NT-H1 thermal compound Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua’s NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability. 6-year manufacturers warranty Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-F12 features an MTTF rating of more than 150.000 hours and the entire NH-U12S package comes with a full 6-year manufacturer’s warranty. 250W TDP Cooling? The AMD Ryzen Threadripper series consists of powerful processors with higher cooling requirements. While standard mainstream processors usually have a TDP rating of 65-105W AMD Ryzen Threadripper (and Eypc) models are available with TDP ratings of up to 280W, which provides challenges not only for the CPU cooler as such but also for chassis ventilation. According to Noctua it could be possible to use this CPU cooler on a CPU with a TDP of 280W, please see this page for further information. It is imperative a second fan is used when using a CPU with a rating of 250W or above, for example the 3rd Gen Ryzen Threadripper, which is 280W. Please purchase a second fan if required. PLEASE NOTE: The NH-U12S TR4-SP3 is a dedicated version for the AMD sTR4X/TR4/SP3 socket. Due to its customised larger base, it cannot be used on any other sockets and is incompatible with Noctua’s standard mounting kits.
