ubuntu mod bios using polariseditor

[amd1361]

hi
i would like to switch from windows to ubuntu os,but as far as i know it is really difficult to control and adjust gpu core voltage and fan speed there.my question is that ,how i can edit my rx470 bios using polaris bois editor to first set the fan speed to 48% (all the time) and reduce core voltage about 80 mv.(my ideal fan speed and gpu volt in windows)
i don't want to risk bricking my gpu.
thanks

You have to use windows because ATIFlash won't work even in Linux.

Fan settings are bottom right.. Set you max clock speed, memory, and voltage.

Adjust fan speed to 48% through range and you should be good to go.

You've also got thermal throttling so check that too.. You can also limit the power draw on the card via "Powertune"

thanks for your reply
Is it possible for you to tell me exactly which item at fan setting must be changed to 48%.and which is related to gpu core volt (which must be changed)
sorry but i am a newbie.
thx

Where can I find that version to download?
