"Yes, please do not cover them up! Jaguar draws air through the top vent and expels it out the side
vents. If any of these vents are blocked, it reduces the airflow through the unit and affects the cooling
of the power transistors (MOSFETs). Similarly, we also recommend against placing Jaguar (MDL‐BDC)
modules directly next to each other (touching) so as to reduce any conflicting airflow."
They recommend it, but im not too worried, they have room to vent.
