The AMD Ryzen 5 9600X is coming soon, what CPU cooler should I pair with ?
I would recommend going with the Noctua NH-D15 air cooler for the Ryzen 5 9600X. The NH-D15 is one of the best air coolers on the market with excellent cooling performance that rivals many all-in-one liquid coolers. It has a dual tower design with two 140mm fans for great heat dissipation. While it's a big cooler, it will fit in most cases and keep your 9600X running very cool, even when overclocked. Noctua makes top-notch coolers and you really can't go wrong with the NH-D15.
