I'm planning on buying my first Noctua cooler ever! Is the NH-D15

I'm buying a new CPU next month and I wanted the best cooler possible for it, so I did a research and found out about this specific cooler. I've also heard people recommending me an other brand Thermaltake Peerless Assasin, I personally don't want to risk cheaping out on a cooler. I've been using only stock coolers for now, and I really want to upgrade it finally to a high-end premium one
