What To Know Before You Buy
Check that you are choosing the LBC version for your CPU and platform, as this model is specifically aimed at relatively flat CPUs such as AMD AM5 and AM4. If you are using Intel LGA2066, the optional NM-i20xx kit is mentioned as required. Review the stated clearance figures if your build has taller RAM or a tight PCIe x16 area.
It is not recommended for Intel LGA1700, LGA1200 or LGA115x, so confirm your socket before ordering.
Common Buyer Questions
Which sockets is this version intended for?
It is described for AMD AM5 and AM4, and for Intel LGA2066 with an optional NM-i20xx kit.
Should I choose this version for Intel LGA1700?
No, it is specifically not recommended for Intel LGA1700, LGA1200 or LGA115x.
How much RAM clearance is stated?
The description states 59mm in single fan mode and 32mm with both fans.
What fan features are mentioned?
Two NF-A14x25r G2 140mm fans are stated, with speed-offset, Low-Noise Adaptors and PWM automatic speed control.
Final Buying View
Choose this cooler if you need the NH-D15 G2 LBC version for a compatible AMD AM5 or AM4 build, or for LGA2066 with the optional kit. The main buying check is socket compatibility, followed by clearance for RAM and motherboard layout.
Why Buyers Choose It
- 8 heatpipes and 20% more surface area are stated, which points to the revised second generation design.
- Two NF-A14x25r G2 fans with PWM and Low-Noise Adaptors are mentioned for automatic speed control and acoustic tuning.
- Recessed lower fins are stated to clear top PCIe x16 on most current motherboards, which is useful in tighter layouts.
How It Works
- Check that your socket matches the stated LBC use case before ordering.
- If you are using Intel LGA2066, note that an optional NM-i20xx kit is required.
- Review RAM clearance and PCIe x16 clearance against your motherboard layout.
- Use the fan arrangement that suits your build, noting that the clearance figures differ between single fan mode and both fans fitted.
Real World Use
In a finished build, this cooler sits over the CPU and its dual tower format means the fit around memory and expansion slots matters. The stated recessed lower fins and RAM clearance figures are useful if your motherboard has tall memory modules or a crowded top PCIe area.
