Noctua is on a roll, since they decided to offer some of their most popular products in an all black flavour. When they released the L9i chromax.black we were informed at that time that there will be no plans to offer the same treatment to the AMD variant, the L9a. Like we saw in our previous review, just take any L9i and add the AM4 bracket kit (which is sold separately). Tthat was the workaround to use it between platforms, so you didn’t miss out on the chromax.black treatment for your AMD CPU.

But the L9a is a bit special, since it has a bigger (longer) heatsink over the L9i. Also it will spare you of the trouble of having to buy that extra AM4 kit. We did cover in the past results from comparing the L9i to L9a and discovered that realistically the difference is very small, only 1-2 degrees favoring the l9a and only in high loads. Nevertheless, let’s see now the L9a chromax.black in action !
