Plenty of airflow and keeps my CPU cool as a cucumber even at it's lowest RPM. Love the blue LED on it and the fan controller is pretty neat. I hooked it up to the back of my case and put the wires in the watercooling port, looks fancy imo. This thing is LOUD, though! (Unless you keep it at the lowest setting, which I do) And I've cut my hands up on it quite a few times just bumping it. It's also pretty bulky.

The heatsink is excellent and looks great to boot. The fan is just so-so. It's not the quietest in the world. It has a manual speed control knob which might seem like a nice feature, except that I forget to adjust it meaning I end up leaving it on high most of the time just to be safe. Annoyance aside, it keeps my CPU frosty even under load.

from completed build Ryzen upgrade to Purple Menace

One of the best cpu air coolers i think for the size and compatibility with m-atx cases and some m-itx cases. Since the entire unit is made of pure copper the heat dissipation is insane, running the Ryzen 5 1400 at 3.7/3.8 GHz at 25-26C idle and just under 60C on full load using Prime95/Aida64.
