Should I install the fans in push or pull on the radiator?
We strongly recommend a push setup for the best acoustics: mount the fans so they push air through the radiator rather than pull air from the radiator. For performance, the results are similar with both push and pull.
Where should I install the radiator in my PC?
In general, if you wish to prioritise your GPU temperature, install the radiator at the top of your case. To prioritise CPU temperatures, install the radiator at the front of your case instead.
Can I use the NL-LC1 cooler on sockets other than AMD AM5/AM4 & Intel LGA1851/1700?
Free mounting parts can be requested through the Noctua website to install the cooler on older platforms such as LGA1200/115x, LGA20xx Square ILM, AM3+.
