Microphones consume very small power, only tiny amount heat generated and could even not be detected. (Total maximum with 8 microphones, 1.09 watts)
The small holes are not for thermal consideration, but for cable through.

Hi. The reference to a "thermal exhaust port" on your sphere microphone ... I'm pretty sure it was actually a "Star Wars" joke.

--best regards
music > microphones > a recorder of some sort

probably because the sphere resembles the Empire's Death Star to the member who typed the joke.    Just guessing, but I am sticking by my guess    >:D
music IS love

When you get confused, listen to the music play!

Cannot say CSM88 is the finest Blumlein stereo microphone, but...
It is the only single body, 1/2" true condenser Blumlein base on a pair of single diaphragm structure.
All the other single body is large condenser (not single diaphragm), or ribbon.
Or, it is single diaphragm, 1/2" true condenser, but not single body (have to mount them together).

So, I came up with this design: Almost single body (pre-mount into a minimum size, and operate as if it is single body), still Blumlein stereo and 1/2" true condenser.
But, user can re-configure easily, and the capsules can be mounted elsewhere, to form a different pickup setup.
Which one you prefer?
