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-U14S 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 and Noctua’s proven NT-H1 thermal compound, the NH-U14S TR4-SP3 forms a complete premium-quality solution that combines maximum performance and superb acoustics for enthusiast-grade TR4/SP3 systems.

With six heatpipes, a fin surface area of more than 6000cm² and the large NF-A15 140mm fan, the NH-U14S TR4-SP3 provides a superior level of cooling performance that makes it ideal for the most high-end, enthusiast-grade TR4/SP3 systems.

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!

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.

Built with Noctua’s AAO standard and sophisticated aerodynamic design measures, the NF-A15 has built up a reputation as one of the best 140mm heatsink fans on the market.

Pros: - Huge heatsink and fan to cool these huge thread ripper cpu's - Ran some heavy editing and rendering and the heatsinks were super cool and CPU temps under load were VERY cool
Cons: - May not fit all cases or MOBO's. Make sure you know what you are getting into when purchasing this fan. Its only a CON if you didn't do your research, but you must make sure its going to clear your ram, mobo, GPU, etc.
Overall Review: I am running a Thermaltake P3 open case with an ASRock X399 Taichi MOBO, I did have to move the fan up on the heatsink about 1/2" to accommodate the ram sticks. I went with G Skill Trident ram and they are a little tall and hit the fan.
