We also knew that out of the box the Core i9-9900K would deliver the exact same performance using the be quiet! Dark Rock Pro 4. Rather we budgeted for a solid $75 air-cooler that we would recommend to those looking for enthusiast-level hardware.

At the same time, we weren't out to destroy Intel's price-to-performance either, so we didn't factor in the cost of a more sophisticated, $160-plus Corsair all-in-one liquid cooler. But this wasn't the intention at all, rather we wanted to leverage what they had to offer (again, it's included after all). You could argue we were doing AMD a solid by testing their CPUs with the box cooler as this could swing things in their favor when it came to the value analysis. Moreover, the marginal boost in clock speed had little to no impact on performance. Our day-one testing showed that although the Ryzen 9 3900X and Ryzen 7 3700X boosted better with improved cooling, we were only talking about a minor increase in frequency. We realized this probably wouldn't satisfy everyone but considering it's included in the price and we've seen decent results on previous generations, it's what made the most sense at launch.įollowing up to that testing, today we're going to compare how the Ryzen 9 3900X performs using the Wraith Prism RGB stock cooler against a big 360mm all-in-one liquid cooler from DeepCool, their new Castle 360EX. When we reviewed 3rd-gen Ryzen we deliberately used the included box coolers for the majority of the testing.
