This was exactly what I needed for my Wraith Prism CPU cooler. I bought my new processor and soon found I couldn't use it as it was a "hook type" cooler which was a lifesaver! It is unobtrusive as it is all black and works absolutely perfectly. The material is plastic I think, but I haven't had any problems with it so far. These are the correct AM4 dimensions (90 x 54mm) but make sure you buy it with reviews like this inspiring confidence in the dimensions. While contemplating the purchase, I came across another post almost identical to this one and all the reviews complained that it was in AM3 format. At least for that I can guarantee that these are the right measurements. If, like me, you're throwing away the standard CPU bracket that came with your motherboard, you can't go wrong for $8.
