You want it on till 30c? You can change its fan curve to something like
. The problem with that is the PC will end up with a fever that'll bring thermal throttling and other bad bad problems and issues. Also if you made a curve like that MSI AB would spit back an error. EVGA Precision XOC would do the same.
That obviously can't be what you want so you just do the opposite.
. Some fans may not stop. They may have a minimum speed.
