Bug Description

With my profile using
Daemon (tpfand) version: 0.95
GTK+ configuration UI (tpfan-admin) version: 0.96

The fan works and does what it should (raise to 15%, raise to 75% at certain intervals) but the display with the temperature bars does sometimes not get updated when the temperature goes down from the 75% region to the 15% region, it actually does but a yellow part of the bar remains in the 75% region and thus the fan keeps rotating at 75%. I would have to unlock and click something so it gets updated and also then the fan goes back to 15% as it should have before.

It is not a critical bug (the fan just runs too long too fast when the temperature has gone down a long time before).

Isn't that what the hysteresis setting is supposed to regulate?
If the fans turned down immediately after you drop below a certain temperature, your machine would soon heat up again and the fan would repeatedly spin up and down after the temperature dropped again, which is annoying to many people.
That's why let it run for some time after the temperature has gone below the threshhold.
If you want to reduce this time, set a lower hysteresis value in your profile.

Hope this answer helps ;)

To be honest, just leaving the temperature-bar high, even if it is way lower, is not intuitive.
Instead, I would suggest having a value that defines the timedelay in which the fan should still run after the undercut of the set temperature.

I actually like the new "advanced setting" menu with the hysteresis value. That's exactly what I meant, thank you! :)
