So I understand the fundamentals with static pressure to "push" through some form of restriction (radiator or dust filter) vs high unrestricted air-flow. But where do you draw the line where "the more you spend, the less return you're actually getting" ? I wouldn't mind if my CPU is running at 60C load instead of 55C if it meant half the cost and/or half the noise level. At the moment I'm eyeballing Noctua fans (NF-P14s) since I don't know any better. Is $20/fan the sweet spot these days? Let me hear your top choices and order of preferences when it comes to case and radiator fans (price, performance, and noise). Do you buy two different types of fans or do you usually just buy an "all-rounder" to keep things simple? I didn't factor in RGB since it is purely cosmetic but if you swing that way be sure to note it.
