Have you disconnected the Octo, or the whole computer from the power for a few minutes?
This should help in most cases.
Thanks for the reply. I turned everything off and left the power off actually switched off the PSU for a day with no change. I completed uninstalled the software and removed all the settings, same thing happens after a reinstall.
Whenever I change any settings on a fan nothing seems to update. If I then exit and re-enter the software all settings have reverted back to everything sitting at 100%.
