i jave ubuntu and every single fan in my pc is running at full speed. (stock amd cpu cooler, 3 front intake, 1 rear exhaust, and gpu). today is my first day on ubuntu so i would like to know if there is any free fan controller software. i dont know how to do it in my bios if that is possible. Linux is still a maze to me. thank you for your time

you have full system control in linux, you don't really need a dedicated application for fan control, you can access all hardware directly and easily script your own scenarios to suit your build exactly. A preset fan control software would not make much sense because of the multitude of hardware configurations in linux. There is stuff available though, mostly in the form of plugins or extensions or .conf files.
You could use Conky to display fan speed and then write a script to adjust that speed. An hour and a half of work at the most.
