Still don't get that, but hey; who am I?I'm assuming the fan curve you mean the dtparam options? if so then yes, thats how i currently have it.you can have your own fan curve i.e. or take ownership of the PWM output via a custom overlay i.e.
https://github.com/raspberrypi/linux/bl ... .dtsi#L370
5 steps is quite limited though, especially since in a matter of seconds the heat can rise to ~70C or higher.
i was hoping to be able to take manual control since i can have it run based on system state. (current spike is followed by rapid heat, or if stuff is off no fan at all)
i also never played with overlays before, i'll need to look at how that works.
since i have a habit of breaking systems... i was trying to have to make as little device tree/overlay changes.
As changing the felt behavior of the on-board fan connector might be over your head why don't you consider to make use of a fan connected to one of the Pi5 HW PWM channels (you have 4 of them in total) available on GPIO?
A simple overlay will invoke a PWM and you will be able to change the duty cycle at will.
The Pi has thermal throttling, so would be surpided if you're able to still break it.
