I purchased this cooler on Amazon for use in my Dan A4 v1/Ryzen 3700x build to replace the Noctua L9a (with shroud) I have been using. I used the Noctua backplate and swapped the fan to a spare NF-A9x14 PWM, oriented to blow towards the motherboard (the included fan can not be flipped, the blades will hit the fins). Temps rose quickly to +90C in prime95, which I attributed to the picture above. The bracket stripped when I was securing it, not allowing adequate pressure against the CPU. The mounting screw wasn't cross threaded, I think I received a dud.
