The NH-D9L features 4 heatpipes and is 15mm lower than classic 9cm coolers, which guarantees full 3U compliance but also makes the NH-D9L compatible with compact HTPC and Small Form Factor cases that have airflow paths parallel to the mainboard. Like the NH-U9S, the NH-D9L has a 95x95mm footprint and thus provides 100% RAM and PCIe compatibility on all Intel and most AMD based mainboards.
The NH-D9DX i4 3U is the same heatsink as the NH-D9L but comes with
LGA2011 mounting for both Square ILM and Narrow ILM Xeon platforms as
well as support for LGA13x6.
All three new models come with Noctua's NF-A9 PWM 92mm fan for quiet cooling performance. They support the SecuFirm2 mounting systems, come with Noctua's NT-H1 thermal compound and are backed by full 6 years manufacturer's warranty.
All three models are currently shipping. The manufacturer suggested retail prices are as follows:
NH-U9S: EUR 54.90 / USD 59.90
NH-D9L: EUR 49.90 / USD 56.90
NH-D9DX i4 3U: EUR 56.90 / USD 59.90
