Noctua NH-L9i-17xx chromax.black
The Noctua NH-L9i-17xx chromax.black is a compact processor cooler designed for Intel LGA1700 and LGA1851, combining a height of just 37mm with quiet operation at a maximum of 23.6dB and a fan speed of up to 2500RPM with PWM control support. This low-profile cooler in a black finish is the ideal solution for HTPC builds and Small Form Factor cases, where it offers compatibility with RAM modules and PCIe cards thanks to its 95×95mm dimensions, which correspond exactly to the Intel socket keep-out zone specifications. The cooler is equipped with an NF-A9x14 PWM chromax.black fan featuring AAO technology. The soldered interface between the heat pipes and fins ensures long-term reliability and, together with the NT-H1 thermal compound, provides optimal cooling performance with minimal noise. It comes with the low-profile SecuFirm2 mounting system without a backplate for easy installation.
Key features of the Noctua NH-L9i-17xx chromax.black processor cooler
- Ultra-low profile of only 37mm allows for installation in compact HTPC and Small Form Factor cases with minimal space
- All-black chromax.black design with a black-coated heatsink, black fan and black mounting parts
- Full compatibility with RAM and PCIe cards thanks to its 95x95mm dimensions, which perfectly match the Intel LGA1700 and LGA1851 keep-out zone
- NF-A9x14 PWM fan with proprietary AAO technology and aerodynamic design supports PWM speed control
- The backplate-less SecuFirm2 mounting system, custom-designed for the LGA1700 and LGA1851 sockets, ensures easy installation
- Soldered joint between the heat pipes and fins guarantees lasting thermal performance without degradation
Chromax.black design for modern builds
The entire cooler is designed in an all-black finish, from the coated heatsink and fan with anti-vibration pads to the mounting screws and components. This stealthy design fits into all-black builds and integrates easily with any case colour scheme.
Maximum compatibility and accessibility
The 95×95mm dimensions correspond to the space defined by the Intel LGA1700 and LGA1851 sockets, so the cooler does not interfere with RAM slots or obstruct the surrounding VRMs. On mini-ITX boards, where the PCIe slot is often located right next to the socket, the NH-L9i offers full compatibility with graphics cards. The compact dimensions also make it easier to access connectors near the socket, even on densely populated ITX boards.
Components and long-term reliability
The NF-A9x14 PWM fan uses an AAO frame and aerodynamic optimisations to ensure quiet operation with fully automatic speed control. The included Low-Noise Adaptor lets you reduce the maximum speed from 2500 to 1800RPM for near-silent operation with lower-power processors. Unlike competing solutions with press-fitted fins, the NH-L9i has fins that are soldered to the heat pipes, which eliminates the risk of joints loosening due to thermal expansion and guarantees consistent performance. The backplate-less SecuFirm2 mounting system simplifies installation while maintaining reliability, and the package also includes NT-H1 thermal compound.
