Once a program shuts off, my CPU temps always go back down into the 30C range immediately. The AIO is set up on a factory auto curve so it's only like 800 RPM at idle. It seems to not go past 60-65C so far, so I bet that's when that AIO starts really spinning up like a madman. I think it does 2800 RPM unless it goes into to overheating where it'll do 3500 to save the CPU. I'm probably gonna run the Ryzen Master all the time and just check up on temps as I go along, until I trust what I built and get used to it.
