Yeah beQuiet!'s products do look great (and offer good bang-for-buck), which was one of the main reasons why I also went for the DRP4 and not Noctua NH-D15. That Cooler Master CPU cooler is great value for 40$.
Yes, I think even the regular Dark Rock 4 without the "Pro" could be slight overkill for the 3600, but if money's not an issue, sure go for it.
I would be leaning more towards something like the Cooler Master Hyper 212 Black Edition, or anything similar. Should give plenty of headroom for overclocking, and you can always add anorher fan to the tower for a push-pull fan configuration for even better thermals.
The Dark Rock Pro 4 is a 250W TDP premium aircooler, which is more than adequate for an overclocked 9900K. The same goes for Noctua NH-D15, which is slightly better in terms of cooling performance (1-3 degrees Celsius), but just slightly louder.
There is no need for a liquid cooler, as TDRP4 does better cooling than most 240mm AIO's for example. Custom-loop liquid cooled setups are a matter of their own.
My 9900K @ 4.8GHz is always way below 80 degrees in gaming, some workloads like Adobe Premiere rendering goes slightly above that, but that is still easily inside safe operating temperatures of the CPU.
I also use ThermalGrizzly's Kryonaut as TIM, so that helps too.
You're absolutely right about the bottlenecking, and that's a quite good plan!
That's alright, I'm also a fan of building budget PC's and getting the best possible "bang-for-buck". The RX 580 is an amazing value card, and I used to have one just a month ago in my "Kolink Rocket" build.
If you'd ever decide to go for a RTX 2080, you should make sure that the CPU isn't a big bottleneck for it.
Great looking build with fantastic components!
Hey, and thank you!
Anything I can throw at it actually, except for Control game @ max with Ray-tracing @ 4K (dips way below 60fps).
I actually did! And thank you for the kind words! That modular PSU (Corsair 600W) is on my upgrade-list for early next year, so I know exactly what you're talking aobut :) Perhaps even getting a Ryzen 7 3700x too.
I first thought you commented on my Kolink build, whoops :b Yeah it's great for 4K Single-players, and for 1440p on esport-titles.
Cheers! Scale is important! ;)
