Can the D6x00 series be Overclocked in any way to improve 3D playback performance, streaming etc?

Have you prepared bigger heatsink or maybe silent water-cooling system for your overclocked TV?

I also have a satellite receiver (AZbox Ultra) some time ago the manufacturer released a firmware upgrade with a setting option to overclock the CPU without any additional heatsink or fan, this improved the performance for streaming etc.
I therefore wondered if a similar fix was possible to improve the Samsung's performance.

No hope samsung releases new firmware with some low level "hacking" features.
They are preparing new firmwares only to forbid access to TV at all. You can just dream about overclocking. Latest firmwares disabling root access and custom apps like SamyGO.

Samsung already use whole aluminum frame as a CPU heatsink
There is thermal pad located under CPU, back side of the board.
