[UPDATE] A solution to issue #1 has been found:

I just wanted to provide this update in case it might be helpful to others. This solution may have already been posted in these forums elsewhere. I know that I had read it a couple of times during my web searches about the issue, but I didn't understand the fix at the time.

As described in the issue below, when you manually set the fans to a percentage speed, it doesn't permanently save to the onboard memory. In order to ensure that the fans don't spin up to 100% on boot, you have to set a 'failsafe speed' for all of the fans. Create a software sensor that references a real sensor. Then set the 'failsafe speed' to something reasonable. I went with 35%, but this build is packed with 140s. Then save the settings as a profile (not sure if this step is necessary, but it can't hurt). The fans should now run at the failsafe speed upon boot until the Aquasuite service or your preferred software takes over control. If you are using a different software for fan management, be sure to disable the Aquasuite service from startup to avoid any potential conflicts.

Howdy! I'm having two issues with my AquaComputer QUADRO fan hub and the Aquasuite software. I don't know if they are related or not. My use case is that I'm using 'Fan Control' in Windows 11 and 'Cooler Control' (formerly Coolero) in Linux on my new build. I needed a new fan hub because my preferred control programs aren't detecting the sys fans on my MSI x870e mobo and I didn't want to pull my Corsair Commander Pro from a different system. The AqauComputer hubs seemed to be pretty highly recommended, so I purchased the QUADRO. Both programs are recognizing and controlling the fans on the hub with no issues using the relevant plugins.


Issue 1: The QUADRO's default behavior keeps resetting to spin the fans at 100% prior to the loading of the background services of the control software. In Windows, I terminate the Fan Control service, launch Aquasuite and the Aquasuite service, and set the fans manually to 35%. I believe this is supposed to save the setting to the onboard memory of the hub. The fans will then run at 35% like they are supposed to. I then terminate the Aquasuite service and set it to disabled in 'services.msc'. I relaunch 'Fan Control' and ensure that it is set to auto start at Windows login. The fans will correctly run at 35% upon system boot until 'Fan Control' or 'Cooler Control' takes over for one or two system boots/reboots. After one or two boots, it seems that the QUADRO hub resets it's memory and starts spinning the fans at 100% again. I have repeated this process multiple times and it has behaved this way each time.


Issue 2: When launching Aquasuite, Windows blocks the Winring0 driver due to the inherent vulnerabilities. A comment in these forums indicated that AquaComputer was working on a new driver to replace it 5 months ago. Have there been any status updates on that? Other developers moved away from it's use. 'Fan Control' switched over to the PawnIO driver a day or two after Windows blacklisted Winring0. I don't know if this is related somehow to my main issue with the fan speed. Please let me know if I am missing something.
Thanks for any advice!
