specific non-linear fan

[uMaoow]

Hello,
I installed afancontrol yesterday and have an issue with one of my fans,
it's a gpu fan primary set to don't activate under some temperatures, it is pretty loud and even if I want to change its operating speed/temp I still want it to don't activate under some temps.
the issue is that its curves aren't linear, it doesn't activate under a 70 PWM, so if i set its line start to 70 it will always be on, if I set it under it regulary triggers the panic mode.
is there a solution to manage that kind of behaviour ?
thank you.

never mind I figured out about the "never_stop" option, sorry for disturbance, thanks again for that program
