In your case, I'm willing to bet that you have experimented with setting the Manual speed to 1500 RPM at some point in the past. Rather than settling on the 1100 RPM set in the low temperature bound, mine is now stuck on 1300 RPM. In my case, where I had experimented with setting the Manual speed to 1300 in the past, I can reproduce this bug by simply switching from SMART to Auto and back to SMART again. If you play around with the Auto, Manual, and SMART buttons, the app will get 'stuck' at the incorrect fan speed (as you show in your screenshot). Unfortunately, you've also gotten a lot of useless answers from our fellow forum users. Great app, but I see you've stumbled across the same bug as me.
