Noctua NH-U9 DX-4677

The Noctua NH-U9 is a high-end heatsink and fan cooling system, featuring a pair of in-line 92mm fans. By using smaller fans than 120 and 140mm designs, this model is able to better fit motherboards where larger versions would block the top PCI-Express slot as well as in slimmer chassis. As with all Noctua models, it provides excellent cooling with quiet operation - though it does sacrifice a little in both of those metrics compared to bigger tower coolers.

This particular variant, the NH-U9 DX-4677, is specifically designed to fit Intel LGA 4677 socket processors like the Xeon W-2400 and W-3400 series.
