Noctua’s DX line CPU coolers have become a default choice in premium grade quiet cooling solutions for Intel Xeon processors. The NH-U12S DX-3647 features a larger, custom-designed contact surface and supports both square and narrow type LGA3647 platforms. Based on the proven, 120mm size NH-U12S heatsink and equipped with two of Noctua’s award-winning, PWM controlled NF-A12x25 120mm fans, it provides an excellent balance of performance, compatibility and quietness of operation. Topped off with the professional SecuFirm2 mounting system and pre-applied NT-H1 thermal compound, the NH-U12S DX-3647 forms a complete premium quality package for quietly cooling LGA3647 based Xeon workstations and servers. Please note that the NH-U12S DX-3647 is a dedicated version for the Intel LGA3647. Due to its customised larger base, it cannot be used on any other sockets and is incompatible with Noctua’s standard mounting kits.

  • 5 heatpipes and premium grade 120mm fans for excellent cooling efficiency, slim 120mm size for high compatibility, ideal for quiet workstations in noise sensitive applications (A/V, engineering, etc.)
  • Supports narrow and square type LGA3647 sockets for Intel Xeon Scalable (Platinum, Gold, Silver or Bronze, Skylake-SP/Purley) and Xeon-Phi platforms (Knight’s Landing, Knight’s Mill)
  • Two state-of-the-art NF-A12x25 fans (push/pull dual fan configuration), supporting PWM for automatic speed control through the motherboard: silent at idle, full CFM performance when necessary
  • Pre-applied NT-H1 thermal compound and easy, straightforward installation thanks to SecuFirm2 mounting system and included processor clips
  • Trusted Noctua quality backed up by 6-year manufacturer’s warranty
