Noctua Premium Grade 92mm Fan CPU Cooler For Intel - Brown| NH-D9DX i4 3U

Keep your processor chill with the Noctua Premium Grade 92mm Fan CPU Cooler For Intel - Brown| NH-D9DX i4 3U from Noctua. Designed for quiet airflow, this cooler features a single 92mm fan and aluminum radiator, as well as a nickel-plated copper heatsink and tubes. Users can install a second fan on the radiator using the included fan mounting clips, and the included NF-A9 PWM fan supplies up 46.44 CFM at 400 to 2000 rpm and 22.8 dBA. An included Low-Noise Adapter allows for even lower noise levels, up to 16.3 dBA, at the cost of a decreased max fan speed of 1550 rpm. This fan uses an SSO-bearing design and has a lifespan of more than 150,000 hours. The Noctua NH-D9DX i4 3U is 100% RAM compatible with Intel LGA 2011, 1366, and 1356 sockets, with no overhang or interference with memory slots. It's also compatible with LGA 2066 slots, and LGA 1366 slots with a Xeon backplate.

3U Compatibility
The NH-D9DX i4 stands only 110mm tall. This is 15mm less than previous 4U-compliant 9cm DX-line coolers and allows the NH-D9DX i4 to also fit 3U cases for applications in fields such as audio or video processing.

100% RAM Compatibility
With its 95x95mm footprint, the NH-D9DX i4 does not overhang the RAM slots on square ILM LGA2011, LGA1366 and LGA1356 sockets. This gives the user full access to the memory modules and guarantees compatibility with tall heat spreaders or optional memory fans.

PWM Support and Low-Noise Adapter
The NF-A9 92mm fan supplied with the NH-D9DX i4 supports PWM for convenient automatic speed control through the motherboard. In addition, the maximum fan speed can be reduced from 2000 to 1550 rpm using the supplied Low-Noise Adapter for even quieter operation.

SecuFirm2 Mounting System
Noctua's SecuFirm2 mounting systems have become synonymous with quality, safety, and ease of use. Supporting Intel's LGA 2011 (both Square and Narrow ILM), LGA 2066, LGA 1356 and LGA 1366 Xeon platforms, the SecuFirm2 mounting included with the NH-D9DX i4 ensures adequate contact pressure on all sockets.

Dual Fan-Ready
The NH-D9DX i4 includes an extra set of fan mounting clips for users who want to achieve even better cooling performance by adding a second, optional NF-A9 to the front fin stack. Using the y-cable supplied with the NF-A9 PWM retail fan, both fans can be connected to one CPU fan header.
