It works very similarly to D15S on 12700K but it is a lot smaller and better looking and comes with two flagship NF-A12x25 fans that cost $44 each. I am not worried that this would bend the board and break off during movement either. It feels much more stable because of its size. I think most people should skip D15/D15s and buy this instead. The installation is also easier. I also had a chance to try Scythe Fuma 2 Rev B which cost almost half as much. It is similar in size and performs well but not good enough for 12700K imo. It was definitely running hotter during benchmarks. But if you want to save on cost, I would recommend that, not D15S. This is not twice as good as Fuma 2 overall, more like 20% better. Overall I think the heatsink itself is not anything special, it's the 2x NF-A12x25s that make it work. I think if you buy two of those and put them on a cheaper tower cooler, it would perform similarly. Most of the money here is going to those two fans.
