==General== ==Hardware== ==* This application note applies to Airtop3 is producing audible noise, can I reduce it?==.
* With the voltage changes, the capacitors vibrate from Piezoelectric forces causing them to make audible noise.
* The main source for this noise are from the power circuits of both the CPU and internal GPU.
- While in splash screen, press '''[F11]''' (instead of Delete) in the keyboard.
- Go to ''''Advanced'''' tab -> ''''Setup items availability'''' (first item in Advanced tab) -> Choose ''''Development''''.
- <span style="color:#ff0000">'''Caution''':</span> Now a the full setup menu is open, including options that can impair the Airtop3 stability or functionality, and items that were not checked or don't work. 
2. In 'Advanced' tab -> ''''Power & Performance'''' -> ''''CPU -Power Management Control'''' -> ''''C states'''' -> Choose ''''Disabled''''<br>
3. Back to the tabs menu (2x '''[Esc]''' button) -> ''''Save & Exit'''' tab -> ''''Save Changes And Exit'''' -> ''''Yes''''.
<br><U>'''Note'''</U>: Disabling C-states may reduce power efficiency of the CPU
<br>
<br>
- ''''RC6(Render Standby)'''' -> ''''Disabled''''
- ''''Disable Turbo GT frequency'''' -> ''''Enabled''''
3. Keeping the C-states disabled: - In ''''Advanced'''' tab -> ''''Power & Performance'''' -> ''''CPU -Power Management Control'''' -> ''''C states'''' -> Choose ''''Disabled''''<br>4. Back to the tabs menu (2x ['''ESC'''] button) -> ''''Save & Exit'''' tab -> ''''Save Changes And Exit'''' -> ''''Yes''''.<br><U>'''Note'''</U>: This configuration may impair the performance of the internal GPU meaning it will not pass it's base frequency.
