I bought an AMD Ryzen 3700X for my new PC, when all assembled te noise from the stock cooler was insane, it was not something I could live with. I did some research and it suggested this Noctua cooler was the best combination of price and performance, CCL had it at a great price and for a few quid more I could get delivery next day (Saturday).
It is incredibly quiet, I don't know it on most of the time, I only ever hear it under considerable load, and then only just. Noctua do a bigger fan/cooler, but it wouldn't have fitted in my case, I'm glad, I didn't need it, this is perfect. I did add the extra fan, but I didn't need to, it knocked a couple of degrees off peak temps at best.
