So that huge CPU spike, based off what I've seen during normal usage where I'm not maxing out the CPU, I set my own AIO curve. It's very low until it hits 45C then it ramps up some to 60% speed @ 60C and then it's basically straight up to 90%@ 65C and the BIOS makes it be at 100% by 70C no matter what. The auto curve was pretty conservative so I had it start ramping up from 0C-45C is 20% speed (~800 RPM). Then it should hit about 1680 RPM (60%) by 60C, then 90% by 65C, then 100% (~2800 RPM). I'll adjust as I see fit. I keep Ryzen Master open literally whenever I'm on my computer, so I'll watch how it spikes. I didn't like how it spiked to 80C, even though it wasn't going past that. That's 176 degrees Fahrenheit. I didn't take kindly to that kind of heat, so I want to try to enact stronger cooling at an earlier stage.
I also set my fan step up back down to 0 seconds since they won't step up from ~65% until 65C, and then they have a 12 second step down time. That way if it's hoping around, those fans will still be ******* in air through that radiator for 12 seconds no matter what the temp does. I've learned a lot about what heat levels should be under normal usage. This is a 3800xt, so it's gonna get hot no matter what. My max wattage rating on this CPU with overclocking seems to be 142 watts. That creates a lot of heat.
Good news is that it drops very quickly once the processing is over. In literally about a second or two it went from 80C back down into the high 30's, so the cooler is working. I think this 3800xt BISH just gets hot LOL
