The Noctua NH-U14S DX-3647 CPU Cooler (NH-U14S DX-3647) is designed to provide excellent thermal management and quiet performance for Intel Xeon LGA3647 processors.  Specially engineered for maximum compatibility with LGA3647 CPU sockets, the NH-U14S DX-3647 CPU air cooler features high-quality aluminium fins, a large 70mm x 56mm copper base with pre-applied NT-H1 thermal compound, copper heat pipes, an NF-A15 140mm with PWM support, and Noctua's SecuFirm2 mounting kit.
 

High-performance 140mm fan

The Noctua NF-A15 PWM fan is engineered to deliver a maximum airflow of  140.2 m�/h rotating at a top speed of 1500 RPM.  Its SSO2 bearing lets it prevent the fan's acoustical noise from extending past the 24.6dBA level while giving the fan a high MTTF life expectancy of more than 150,000 hours.
 

The DX-3647 version of the single heatsink tower Noctua NH-U14S offers the best cooling performance for Intel Skylake-SP and Intel Xeon-Phi processors.  It is the best CPU cooling option for enthusiasts intending to build a high-end workstation or server based with an LGA3647-sized processor.
