 You don't have to, it's purely optional. From my experience built in (in BIOS) performance modes work well. Limit your power or apply custom fan curves only if you have issues. As soon as you click Apply in the ``Fans + Power`` section BIOS will consider your fan curve as "custom"! (no matter if you modified it or not)
 
 #### How does G-helper control my fan speeds?
-**It doesn't.** Your BIOS does (same as in case with Armoury). What G-helper can do - is (optionally) set a custom fan profile to current performance mode consisting of 8 pairs of temperature + fan speed % via same endpoint armoury seem to use.
