Get some 12 volt power adapters, and some computer fans, have them sucking the hot air out of the top.

cut intake holes at the bottom, twice the size of the fan holes up top.

gotta cover the holes when lights are out though. light leaks will lead to a series of problems.

keep it simple... take the top off the cab, and have a box fan blow in from the bottom
that will keep the temp just a couple of degrees over room temp

check out the home improvement stores they carry inline duct fans that are really easy to wire up to a plug and timer. cheap fix. I have to open my box :jointsmile: during the light phase to help with heat, but I have 60k lumens in a small box. I am sure you lose a bit of light but its a quick fix depending on your location.
