Hardware

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.
  • Disabling C-state should reduce noise from the CPU's power circuit, see below instructions:

1. Activate development setup items of the setup menu:

- 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'.
- Now a 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' 3. Back to the tabs menu (2x [Esc] button) -> 'Save & Exit' tab -> 'Save Changes And Exit' -> 'Yes'.

  • Using a Discrete GPU should naturally reduce the noise from the internal GPU power circuit but there's also additional configurations that can be done from the development setup menu that may help:

1. Enter the development setup menu:

- While in splash screen, press [F11]..
- Go to 'Advanced' tab -> 'Setup items availability' -> Choose 'Development'.

2. In 'Advanced' tab -> 'Power & Performance' -> 'GT - Power Management Control' -> Change the two options below:

- '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'

4. Back to the tabs menu (2x [ESC] button) -> 'Save & Exit' tab -> 'Save Changes And Exit' -> 'Yes'.
