Controle board safety

Hello every body i had some trouble with my controle board and i dont now why its happend.
The carbid team send to me a new one and before mounting it , i want to protect it.
So i plug an inverter to prevent all the electrical nocive variations, but i dont know if i had to keep the controle board inside or outside the sound enclosure. can we put a fan on it to keep it cold?

The controller is mounted on a heat sink when is then bolted to a rail which does an excellent job of dissipating heat.

There was a fan with the launch units, but it was not necessary and has been dispensed w/.
