Noctua 92mm Fan Towers: D9L & U9S
Tower CPU Coolers
Street Price

A new heatsink from Noctua is always worth more than a cursory glance, as this Austrian brand has become one of the most consistent producers of high performance CPU coolers in the past decade. The latest is a trio of tower models featuring a new 92mm fan, models obviously meant to replace the previous NH-U9B SE2: NH-U9S, NH-D9L and NH-D9DX i4 3U.

The U9S features a single fin-stack while the D9L and D9DX feature double fin-stacks. The double fin-stack models are actually identical except for their mounting hardware: The D9L is meant to mount on standard Intel and AMD motherboards while the NH-D9DX i4 3U targets Intel Xeon LGA2011 based workstations and servers. These are the first new coolers from Noctua since the flagship dual 15cm fan NH-D15 was launched in spring 2014.

A scan through SPCR's CPU heatsink review database shows that while we've reviewed a fair number of 92mm and 80mm fan tower heatsinks (mostly years ago before the 120mm fan rose to prominence), the earlier NH-U9B is not among them, a curious omission considering our long relationship with Noctua. The new coolers are welcome additions, given the increasing popularity of smaller mini-ITX and micro-ATX systems for gaming platforms. An initial impression is that they have dimensions not dissimilar to the long discontinued Scythe Ninja Mini, a most useful high performance small tower cooler in its day. Perhaps the new Noctuas can reprise the Ninja Mini's role.

The box and contents. Only the D9L box is shown; the U9S box and contents are nearly identical.

The well-established Noctua system of orderly packaging and useful accessories continues with these new 92mm fan coolers. The heatsink with mounted fan is in one inner box, and a second box contains the hardware in Intel & AMD bags, with a common set of extras. Included are an L-shaped screwdriver, a second set of fan clips, and a low noise fan adapter. Support for a huge variety of CPU sockets is standard, though not the old LGA775 or LGA1366. Users on these outdated platforms are not left entirely in the cold as they are eligible for a complimentary set of Noctua's older NM-I3 mounting kit.
