Note if planning to dual boot Thelio

Windows drivers - to my knowledge - are not currently available for the custom hardware System76 includes with the system. This includes the fan controllers.

So unless I am missing something, if you want to boot any other OS on the system, you need to unplug the fans from the custom hardware, and plug them into the motherboard to avoid having the system overheat.

Why dual boot? My goal is to be able to run Windows in a VM, under the PopOS host. But to really make this functional, aside from the configuration itself, I need a KVM, and the one I want is backordered with dependencies on China getting back to work.

So in the meantime, dual-boot seemed like a good option. The machine seemed really quiet; not loud as reported by other users. Then I noticed that the top of the case was getting really hot when under load. So I checked temps with CoreTemp, and found that the 3990x hit a max of 92C!

Looking at the Gigabyte fan configuration utility, I noticed it only had one fan connected - and then I found out that the custom hardware that is part of the Thelio is only supported on Linux, and is responsible for controlling the fans. Ergo, most of the fans likely were not running at all.

At least with the Gigabyte TR board, it does have enough fan headers to connect all of the fans directly to it. So it's not overly difficult to switch them over, and then fan speeds can be controlled in other operating systems using the Gigabyte utility. Still, something to keep in mind if you're considering dual boot with a Thelio. Also, I hope that now that they are connected to the MB, it will still cool fine when switching back to running PopOS.
