The package includes everything we need for the installation, such as mounting kits for all modern sockets (including the not-yet-released LGA1851), NT-H2 thermal grease, low-noise adaptors, and more. Low-noise adaptors won’t be required if our motherboard can adjust the fan speed to the full range.
The proper base is crucial for optimal performance. Since the NH-D15 G2 has three options, it requires some explanation. Noctua described it well on its website and in videos. I don’t think any other brand handles support and documentation like Noctua.
Below is a detailed description of why we asked for the LBC version for our test rig.
Taking platform-specific optimisation to a new level, the NH-D15 G2 is available in a regular, standard version and two specialised variants:
- The regular NH-D15 G2 is our standard recommendation. It uses the same medium base convexity as most other Noctua heatsinks, which makes it a perfect all-rounder that provides optimal results on AM5 with the included offset mounting and on LGA1700 CPUs when utilising the included NM-ISW1 shim washers (or so-called contact frames) to reduce CPU deformation from ILM pressure.
- The HBC (High Base Convexity) variant is specifically optimised for LGA1700 processors that are used with full ILM pressure or have become permanently deformed in long-term use, providing excellent contact quality despite the CPU’s concave shape.
- The LBC (Low Base Convexity) variant is specifically optimised for relatively flat CPUs. As such, it offers excellent contact quality on AMD AM5 even without the offset mounting as well as on other comparably flat CPUs (e.g. AM4, LGA2066, LGA2011, lapped or custom flat heatspreaders, etc.).
The NH-D15 G2 also introduces new fans designed to generate less noise and provide better air pressure – NF-A14x25r. In fact, no other fan on the market has a similar design. The fan specification is in the table below.
