Das zeichnet den NH-D9 DX-4677 4U aus

Unlike bulkier coolers designed for consumer platforms, this unit combines a compact footprint with Noctua's signature quiet, high-efficiency fan technology. The direct-contact heatpipe base and optimized fin stack provide thermal performance that keeps Xeon processors within safe operating temperatures even under continuous load.

Ideal für...

IT administrators and system integrators building or maintaining dense server racks in data centres, colocation facilities, or enterprise environments. The 4U height constraint is a common limitation in 1U and 2U chassis — this cooler is engineered specifically to work within that restriction while still delivering reliable thermal performance.
