Some weeks ago, we had a chance to review the NH L9i chromax.black cooler, which is designed for small form factor PC with Intel processors. In our tests, we have used the AM4 mounting kit, which is available as a separate product. Since Noctua released the NH L9a-AM4 cooler, which is out of the box prepared for AM4 socket, then it’s time to take a look at this new cooler and compare it to the previously reviewed NH L9i version.
