 ### Configurable fan profiles
 
-Jetson Orin Devices running balenaOS revisions newer than v6.1.24 and supervisor versions greater than v16.10.0 offer support for configurable fan profiles. You can switch between the options provided by Jetpack by navigating to the Device/Fleet Configuration tab on the sidebar in the balenaCloud dashboard and selecting the desired option. The change will be performed during runtime and doesn't trigger a device reboot. Preloading the [fan profile configuration](/reference/OS/configuration/#fanprofile) before provisioning your device can be achieved by editing the [config.json](/reference/OS/configuration/#about-configjson) file.

You can switch between the options provided by Jetpack by navigating to the Device/Fleet Configuration tab on the sidebar of the balenaCloud dashboard, clicking "activate" on the "Define the device fan profile" configuration option, and typing in the desired value. The input value should be a string, without quotes. The change will be applied at runtime and will not trigger a device reboot.

 ### Configurable power modes
 
-Jetson Orin Devices running balenaOS revisions newer than v6.1.24 and supervisor versions greater than v16.10.0 also offer the possibility for selecting the desired power mode. You can choose between "low", "mid" and "high" or specify the power mode index directly by navigating to the Device/Fleet Configuration tab on the sidebar in the balenaCloud dashboard. Please note that your device(s) will automatically reboot to apply the new power mode. The available power modes indexes for your device type are visible in the host OS in `/etc/nvpmodel.conf`. Preloading the desired power mode configuration can be achieved by editing the [config.json](/reference/OS/configuration/#about-configjson) file and specifying the desired [power mode](/reference/OS/configuration/#powermode) before provisioning the device.
