I would start with I don't like that these guys sell locked (non-K) CPUs on Z590 motherboard. The only advantage Z590-A offers over B560 ones is option to overclock K-chip, which they don't even offer you... Add to this that Z590 are significantly more expensive boards and in addition this Asus is quite pricey compared to others Z ones and what it represents. If you wonder, B560 isn't some cheaper garbage for third world, but being able to offer the same quality just reasonable choice for somebody buying non-K chip.
Z590-A is less conservative about Power Limits, but it really doesn't matter, if it's just webbrowsing and chess computer. This CPUs paired with strong GPU and running demanding games pulls <100W, so conclude that with 11700 this passive cooler will just need to deal with another 10W of power than 11400 in such gaming scenario, which according to your words won't even happen.
I forgot my thought about you using case fans in summer with passive build. If you need to do it in terms of needing to lower your CPU's temps to comfortable ones and then fans need to run that fast that you can even slightly hear them - leave this approach. If something like will be needed with new computer we discuss, just buy yourself this thing: https://www.scytheus.com/ninja5
I personally use it with my 9700K, so can guarantee that you won't hear it with two fans running 500, maybe even 600 rpm without sticking your ear to it as normal people don't. Due to it's construction left fan will also serve as case's exhaust fan. So staying literally silent then it will just kill your passive cooler + case fans thermally. No joking - maybe due to your age you use some hearing enhancement, which when you sit next to your computer lets you detect cougar sneaking into your neightbours garden... than I can't discuss :]
