At one point there was a open source project for a linux client, but it hasn't been updated in forever. Unclear if it would even work with new Aquacomputer firmwares.
I too run Linux as my primary OS. I keep a Windows 10 install around just for games. That's pretty much all it is good for these days. I do most of my Aquacomputer setup in Windows. The good part is that the Aquacomputer stores all of its curves and such on the unit itself, so as long as you don't need motherboard/CPU/GPU sensors to control your system, you don't actually need any software at all, once it is set up the way you like it.
I also have a VM with Windows 10 in it and have installed the Aquasuite software there as well, passing through the USB device, for when I need it.
Same here. Only thing I wish existed is a way to send real-time temperature/sensor info to the Windows VM... I have my curves set up based on water temp, which works for normal workloads, but anything that spikes the temp suddenly, throttles my CPU faster than the water heats up... :\
