Power fail or crash due to overheating

Comgrow T300

Hi
The firmware version sent to new T300 is bugged when power fail.
I propose to all T300 user to upgrade to last version v1.5.2 (T300 | Sovol 3D Printer Wiki).

I have build a enclosure around my T300 for print ASA filament. I have add a air extractor.
But T300 is not protected to the heat of bed, then if we have more than 5h of printing the electronics card can have 100°C on it and firmware is crash.
In this case the only solution is power down and wait heat decrease and restart. The new version can continue printing.

Do you have recommandation for me for remove this problem?
For exemple go out the main board to the printer, or add glass wool between bed and main board, or add peltier effect module for cool main board or set only the top of 3d printer in enclose but, not easy to do it, or add fan for air injector below T300,…
Thanks

I built the solution:
I printed a part that channels the outside air blown by a fan and sends it under the 3D printer.
And I also removed the bottom plate of the printer that protects the circuit board.
Thanks
