You will brick the board.

How?

The BIOS file obviously isn't for the board you have or it would work. Different boards have different chipsets, controllers and so on.
Each component has it's own unique microcode it must have to function correctly, if it has the wrong microcode it never works, hence the "Brick" part of it.

That's why, it's to keep you from bricking it.
Always go back with what the board is supposed to have.

The thing is i knew that that's why I did make my own mode using a copy of my original bios but still it didn't work

Keep screwing around till you brick the board. Well, it's your loss.

Chances are the checksum of the file you modded isn't right.
However know this - You could also "Lock" the BIOS chip if the checksum to the file isn't done correctly, that means once it's flashed in you'll never be able to reflash the chip because the file on the chip after it's flashed locks it.

Modding a BIOS is risky, some even refer to it as a dark art and they aren't kidding about it by that term. If you don't know how to mod a BIOS file properly, just don't or you will have a brick on your hands.

You've been warned.

Get a fan controller, you'll be MUCH better off than the way you're wanting to go here.

True why didn't I think about that
But will I be able to have a graf to allow me to change the fan curve depending on the CPU temp?

No, just monitor temps as you run the system under load.
You'll eventually figure out what it needs and be able to deal with it.
