I bought this HSF combination after reading several reviews showing it to be one of the quietest on the market, and after years of sitting next to a noisy PC CPU fan, I was finally prepared to pay its premium price. Noctua has a reputation for quality, and this applies to all of the package, be it the fan and heatsink, or even the manual and the packaging itself. In use the fan is barely audible on a Intel Core i5-9400F 2.9GHz CPU and Asus Prime Z370-P II motherboard. Usually such an expensive HSF is found on overclocked PCs. In my case, I just want a quiet PC, and I've now achieved this. If you're prepared to fork out a lot of money, this HSF is the business.
