Almost every sealed mirror box I saw has one ventilation hole with a fan attached to it. 

My mirror box has three additional ventilation holes (see image). I believe these holes help break off the air boundary layer above the mirror rather than cooling it down, but not entirely sure. Are there any disadvantages with them?

This type of system doesn't cool as quickly as some open back mirror cells do.  But it does work.  You should do pretty well with what you have there now if you allow for sufficient time to cool.  My Astrosystem Quantum was similarly built with one fan.  After an hour or so of cool down though, it was ready to rock n roll.

There is a different school of thought that one hole helps to direct flow to the mirror.
