Hello again,
I just finished installing water cooling kit on my PC and was wondering if these temps look acceptable and if there is anything I can do to improve them if not. Delta T maxed at 12.8C, water temp maxed at 36.1C. This is an hour or so of gaming.

There is a lot of data to absorb there, but if I interpret the labels of your temperature sensors correctly, this looks pretty reasonable, if this is a fully heat soaked system after a period of full load.
CPU's tend to benefit much less temperature wise than GPU's do, presumably because of the heat spreader getting in the way.
Provided this captures a period of high load, I see nothing in this chart that stands out as negative.
You might see a couple of degree improvement in core temps by actually running the pump at full speed, but that's about it.
Thanks for the info. I will do some longer testing to make sure. If I run the pump over 50%, the flow meter makes an awful ticking sound. I've reached out to Aquacomputer and am waiting to hear back about a replacement. I will try higher pump speeds once I get a replacement.
Furthermore, I just realized I've been looking at Tctl/Tdie for reported temp on CPU and I should be looking at Tdie on Ryzen. So... my CPU idles way lower than I thought. I think im happy with this. Thank you everyone for your feedback and help.If the hardware in your sig is current and that is running full tilt with a warmed up loop looks like you are spot on with what you have going on.
Oh, and one final recommendation.
Since you have an aquarium device, maximize your target temp / fan and pump speeds by using setpoint controllers instead of curve controllers.
Curve controllers only work accurately at the max target temp, at every other load they spin the fans faster than necessary, and thus keep the temps below where your intended target is.
With a setpoint controller (aka PID controller) at least than max loads your fans (and pumps should you choose to control their speeds) will target the same target temp at any heat load, and thus at sub max heat loads will have much quieter fan speeds.
Custom PID control is very complicated. People (mostly German manyfacturing engineers) have done Masters and PhD dissertation on getting the PID settings right. The aquaero allows for this under "custom" settings, but I would t recommend it.
Fortunately they have some presets that work pretty well for PC water-cooling setups, so you just choose the desired response speed (slowest, slower, normal, faster, fastest) instead of doing complicated experiments on your loop.
Slower settings lead to more stable fan speeds, at the cost of less accuracy in hitting the temp setting. Faster speeds get to to the temp setting faster, but can lead to rapidly changing fan speeds which can be disruptive, as well as oscillation. (It's hot turn up the fans, shit it's too cold turn off the fans, over and over. I call Thai the girlfriend thermostat effect.)
In my loop "Normal" is the fastest I can use without inducing oscillation.
You may need to set minimum fan/pump speeds for this to work right though, as many fans and pumps turn off below a certain duty cycle percentage, which in and of itself can cause oscillation.
I'd recommend configuring the minimum fan/pump speeds as the slowest duty cycle setting they will actually run at without shutting off.
