Noctua today introduced three quiet CPU coolers for the LGA3647 socket of Intel's Xeon Scalable (Platinum, Gold, Silver, Bronze) and Xeon-Phi processors. Coming in 140, 120 and 92mm form factors respectively, the new NH-U14S DX-3647, NH-U12S DX-3647 and NH-D9 DX-3647 4U cover all bases from large, ultra-high performance workstations all the way to compact 4U size servers. Thanks to their premium-grade Noctua fans, all three coolers are exceptionally quiet and ideally suited for use in noise-sensitive environments.

"Many people tend to think that high CPU core counts and state-of-the-art performance have to go hand in hand with loud cooling fans" says Roland Mossig (Noctua CEO). "Our new DX-3647 line coolers for Intel's LGA3647 based Xeon processors prove that this does not have to be the case. Whether it's a high-end workstation or a 4U server, these coolers allow massive computational power to be combined with whisper-quiet operation!"
