> but really quiet
It’s still gonna be louder than a water cooler if that’s your primary concerns. Otherwise other air coolers are only marginally less silent and just as effective at half (if not less) the price.
In my experience every single (AIO) water cooler I've tried has been significantly worse in terms of noise than a decent air cooler.
Specifically the pumps. Those things have an obnoxious high-pitched whine that I personally find unbearable, especially during low/idle workloads.
It's possible that the actal dB level is lower, but the frequency and sound characteristics matters. A lot.
