I own an octo and never have any problems but a few nights ago I shutdown my pc for the first time in a while (besides restarts for updates) and when I turned it back on my fans are stuck at 100%. Aquasuite always resets to power preset instead of the curve I was using and no matter what I put the power preset to or make a curve for the fans don't change and just keep blowing full blast.

If I close and reopen the software again it's back to power preset and the curve is lost. My virtual sensors are still available.


My computer is literally unusable like this. I have 7 fans and two radiators so when they are going full blast like this I can't even hear myself think.
Nothing inside my computer has changed and I've had no problem for over a year...

I saw your new post expressing frustration that no one has responded to this post so I will give it a go.

This sounds like it could be a profile switching issue. Aquasuite X.45 introduced unlimited Profiles and rule based Profile switching with priority hierarchy. Is it possible that some condition is causing a different Profile to be activated? One where the Octo fan control is set to power preset? Have you confirmed that the Octo profiles are set up properly? Have you checked your Global Profiles and automatic profile switching?

If you are sure that an unanticipated Profile switch has not occurred, some more details might help like manufacturer and model number of the fans you have attached to it, the version of Aquasuite you are running, and the version of firmware the Octo is running. Are the fans each connected directly to an Octo PWM port or are there PWM splitters? Were there any Windows or driver updates immediately before this happened? Is the Octo USB cable plugged directly into a mobo USB2.0 header or is there an internal USB hub? Are there other Aquacomputer devices? What other USB devices are connected? Any new ones?


Since it has been working for over a year, they must be PWM fans. Since you can see the Octo in Aquasuite, the USB connection must be working. Have you tried completely shutting down, turning the PSU off, and pressing the power button a few times to drain any residual charge?

I don't use profiles and never have and the fans wont reflect changes
done to them live. I can do any changes I want and nothing actually
changes. Closing and reopening the software reflects that the settings
aren't saving at all either. Yes I have tried unplugging my psu and discharging any residual power which is actually my first step in troubleshooting anything. Again I don't use profiles and the profile switch is turned off but it shouldn't matter. I didn't update the software or anything since it was working before.

If I save my settings to the
profiles (all of them) nothing changes but next time I start the
software it says "device and profiles don't match" because again it just
defaults to 100%. If I click a profile it will change the settings
reflected to w/e like if I set it to 54% output or something, but again
the fans wont actually change they just stick to 100% and if I close and
reopen the software yet again it is defaulted to 100% but again it
doesn't fucking matter because changing the settings doesn't reflect to
the real world and my fans still sit there at 100% and the software
still reports them at 100%

Here after opening software. It is defaulted to 100%


Here I've changed the settings and the output doesn't change


Here is what I see if I click curve. It is defaulted to not having a source


Here I have added a source but it doesn't matter because again the fans wont reflect any changes made


And
again here is me opening the software again after closing it (and yes I
click the save icon every time) back to being defaulted to power output
100% and the profiles I've saved (just for seeing if it's a profile
issue) are not loaded so it says the profiles don't match, but if I
click a profile the settings will change to that profile but again
nothing actually changes. Fans still just blasting 100% like a jet
engine.

Already done all that and already msged aquacomputer and still no reply.

lost for lost, i'd try uninstalling / reinstalling aquasuite, then going to the Octo System tab to reset it to factory setting and try to create a new fan curve, see if it works.


But still pop an email to aquacomputer support in the meantime, it takes a few days to get an answer so better get it started now in case the Octo needs to get replaced.
