I made some upgrades to my NCASE a few weeks ago, one of which was a Ryzen 3900X. I strapped my Noctua C14 to it and started doing some testing.
I'm finding that I hit the thermal threshold of 95C in Prime95 after about 5 minutes. This results in thermal throttling and the CPU clocks down to about 3.5Ghz.
Current configuration:
Noctua C14 with two 140mm fans set to intake
92mm rear fan set to exhaust
120mm NF-A12x25 next to C14 set as intake
RTX 2080 with Accelero III
2 x NF-A12x25 under Accelero III set to exhaust
My experience with the 3900X seems to mirror that of others. An AIO has been recommended to me as a solution.
Before I pull the trigger, I wanted to poll other NCASE owners. I was always under the impression that air cooling, especially by Noctua, could come close to the performance of an AIO. Maybe with the 12 cores on the 3900X we've reached a point where the AIO shows more benefit.
What kind of noise can I expect with an AIO? I've always liked the noise levels of air cooling, but the behavior of the 3900X is quite different than I'm used to. It sees a lot of rapid temperature spikes which causes the fans on my C14 to spin up and down rapidly. I've tweaked the fan curves as best I can and now I only see this when running Lightroom or under heavy multitasking.
