I've been thinking about upgrading to an i9-9900k, MSI Z390 Gaming Plus, 32GB Crucial Ballistix Sport LT DD4-2666, and I'm still undecided about which case and CPU cooler to get. I really don't want a bulky case. I want something smaller than my CM690 II case. I also understand the the 9900k has a 3.6GHz base clock and a 4.7GHz all-core turbo clock and I would like to have sufficient enough cooling to prevent it from throttling during CPU stress tests. What would be an ideal CPU cooling/case that will keep it at 4.7GHz all-core turbo without throttling for this CPU in CPU stress tests?
