When you open the retail box, you will know it was money well spent.

This fan is dead silent. I had to check to make sure I didn't forget to connect it when I first ran the PC. My Ryzen 5 1600 is at stock clocks and I've never see it go over 64C when gaming. Highly recommend for any slim builds.

Super quiet, especially with the included Low-Noise Adapter! Note that it barely fits with the 'ASRock AB350 Gaming-ITX/ac Mini ITX AM4'; see two pics showing essentially zero clearance between part of the cooler and a couple random sticky-uppy things on the mobo. Being Noctua, the fan's brown, but the innards of my case aren't visible, so I don't care!

This low profile cooler is no problem for the Ryzen 5 1600 in a tight enclosure. Excellent quality and performance!

Surprized by how silent it is even under load. Managed to get overclocking even with such a low profile footprint.

Personally I like the distinct colours very low and fits very nicely in my small case. Soo Far from my testing it keeps the CPU nice and cool.

Great cooler for a sff build, and already having the hardware for a 20mm thick fan was super convenient.

Keeps it cool.

Silent and does a great job of cooling - what's not to love?
