Noctua NH-U9 DX-4189, 2x92 mm CPU Cooler, Brown

This cooler is engineered for dedicated server and workstation environments utilizing the LGA4189 socket, specifically supporting 3rd generation Xeon Scalable and W-3300 series processors. The design employs a single aluminum fin stack cooled by two 92mm fans configured in a push-pull arrangement. Heat dissipation relies on six 6mm copper heat pipes that extend from a nickel-plated copper base plate to the fin array. This robust material combination ensures reliable thermal transfer performance necessary for consistent operation under high processing loads.

The unit features Pulse Width Modulation (PWM) support, allowing fan speeds to dynamically scale up to 2000 RPM. At maximum operational speed, the cooler generates an airflow of 46.44 CFM with a measured noise output peaking at 22.8 dB. The assembled unit maintains a narrow 95mm width, which facilitates 100% clearance for adjacent RAM slots and PCIe components on compatible motherboards. With a total height of 125mm, the assembly is suitable for integration into most space-constrained 4U rackmount chassis.
