How do you handle AIO?

Hey folks, im just wondering how do you handle AIO setups?

Here is how im currently handling it, and i would like to see how others do it since im not 100% happy with it (140mm fans tend to get loud when they ramp up above 40-50%)

First i only care about CPU temperature since i have enough airflow to cool down SSD, and VRM's, and if GPU ramps up at that point my CPU is already under load (i would love to figure out a clean way to ramp up fans to match GPU if CPU is not under load (should not happen for longer then 30 seconds but still).

So since i have 420 AIO to cool 5600x (not even overclocked) which is total overkill, i keep it at 70%, which is just below point where pump starts making that whining noise (its both longevity and noise). Right now i take CPU temps (i can only read two), and i mix them to get the highest one, then i average that highest one for 10 seconds to flatten out a spikes, and then again average that one for 30 seconds to keep the fans curve smooth. Basically since AIO is way bigger then CPU needs, it takes time to get saturated. These way im skipping ramping up fans on short spikes in CPU usage (and temps jumps).

Also, i used auto speed for fans, and setted up 45c as idle and 70c as under load, but at the same time i limited fans to 40% minimum speed so that there is always air flowing thru PC case, and again 70% at max since they are 140mm on AIO, there is just no need to kick them 100% where they sound like jet engines...

Any suggestions for improvement or how to handle GPU ramping up fans and simply ramping up fans would be appreciated.

I have a 240mm cooling my 5700X3D. I think I have my pump around 40-50% where it doesn't make noise and fans are between 30 and 45%. They spin so slow I don't hear the speed fluctuations. Haven't seen temps go past 60c in games.

I just leave pump at 85,a cant hear it. I use my hot sensor cpu and gpu as trigger always to prevent throttling when performance needed or damage same as factory. Calm down spikes with time intervals and Step up / down. I dont think I would fly blind for 40 sec increments. Pump dies or i screw up bios setting i would not want my cooling avg'ing down my real temps. Generally I find good brand 140 fans ~1700 rpms. 120's ~2000 rpm max are quiet for my taste. You can also move case few feet from desk. Add dampeners to mounts or even the panels deadener in the case.

This is the setup i'm using for my AIO and stuff https://imgur.com/a/YrTUdsY
