Managed to get a water cooling system installed for my new 9800x3d cpu, for which I wasn't impressed by the noise or temperatures when using a regular air cooler.

This owns. Much lower temps, much lower noise.

Nice, custom loop or AIO? If custom loop what are people using nowadays for water-blocks on their GPU, did EK survive their 'try just not paying their suppliers and employees' experiment?

What's your workload like, mostly gaming? I feel like the sweet spot for AIO cooling of CPUs is something like 30s to 10 minute saturation workloads. Shorter than that and you're not producing enough heat for your cooling system to matter. Longer than that you're saturating the liquid anyway. But for some GPU limited games and some workstation tasks even a "cheap" AIO has way better peak noise normalized performance than even pretty premium air coolers.

It's an AIO named Arctic Liquid Freezer III 360. :) It was supposed to be notoriously difficult to install, but it went fine as soon as I figured out I had the brackets upside down. The smoother, prettier side needed to be facing down to the mb, quite counter-intuitively.

I'm trying to figure out the best activity/cooling curves. I'm using Argus Monitor.

I've got the connector labeled PUMP plugged into the header aio_pump, and I plugged the connector labeled VRM into either cpu_fan1 or cpu_fan2, and the connector labeled FAN into cpu_fan2 or cpu_fan1.

In the program, there's one thing labeled cpufan running at 640 rpm while at 32% speed - I assume this is the vrm. Then there's auxfan0 reporting 1020 rpm while at 32%. And auxfan1 at 1240 rpm(?) while at a fixed 20% - guess this is the pump. I set it at a fixed 20% because it was making a repeating whining or wind blowing noise every second at higher speeds.

a repeating whining or wind blowing noise every second at higher speeds

Hopefully that goes away as the bubbles in the loop make it to the top.

With a 360, I wouldn't expect a load any normal user would reasonably run on a computer that's sitting in the same room as them to fully saturate the liquid in the loop. Maybe a supper long session of Cities: Skylines II, if you have literally Linus Torvalds needs for compiling Linux, or if your room needs an electric space heater so you run a synthetic benchmark/mine to keep warm at night.

I suspect there's something wrong with the fans.

The VRM fan seems to be the culprit for the annoying noise. The noise changes when I regulate its rpm in Argus. Setting it to bios controlled seems to reduce it the most. It's now noise free at idle. That's the most important thing.

The fans pointed at the radiator seem to be a little off-kilter. The graphic on them around the centerpoint moves.

The fans that were delivered with my case were also messed up. They made a much more high frequent irregular noise, due to bad bearings I think. I had to replace them.

Is there an unusual amount of shittiness in the fan production industry right now?

Edit: I swapped the connections. I thought I had VRM on cpu_fan1. It was on 2. Radiator fans was on 1. Now, with vrm on cpu_fan1 and radiator fans on cpu_fan2, the noise is mostly gone, only appearing briefly during ramp-up! Yay! Hardware idiosyncracies. ¯\_(ツ)_/¯

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
