Mainline Linux kernels use cooling maps for the GPU. If you are compiling your own kernel, you can adjust the trip points. In the stock configuration, throttling only kicks in at extreme temps to protect the silicon from immediate failure, not to maintain performance.
Many custom builds come with Magisk or SuperSU pre-configured. This grants full administrative control over your filesystem to block ads globally or tweak system parameters.
) while keeping it from running too hot, the community generally recommends switching to a "slim" or "debloated" custom ROM. Recommended Custom ROMs Alice UX / Slimbox:

If you are looking for a Linux server or desktop replacement, Armbian is the gold standard. It provides optimized kernels and a Debian/Ubuntu base. Mainline Linux kernels use cooling maps for the GPU
Boot into recovery mode and flash the custom ROM, following the on-screen instructions.
: Known for its polished "leanback" UI, this ROM is often used on the more powerful Allwinner H616 variant to provide a smoother, more universal Android TV setup compared to stock firmware.
Debloating: Removing junk apps that pin the CPU at 10% load constantly. Essential Installation Tips Many custom builds come with Magisk or SuperSU
The progress bar will begin moving. The flashing process typically takes between 3 to 7 minutes. Do not nudge the cable during this time.
SlimBOX TV is a widely used third-party Android TV (ATV) firmware for budget SoCs. It strips away resource-heavy background tasks found in factory software, which immediately reduces core temperatures.
Connect your H6 box to the PC while holding the reset button (usually inside the AV port or on the bottom).
Download the chosen ROM and the PhoenixUSBPro tool. Open PhoenixUSBPro: Load the .img file into the tool.
Disconnect the power cable and all USB peripherals from your Allwinner H6 TV box.
