Hey there MoeSizzlac !,I'm about to build this awesome idea of yours,I'm just wondering if the fan it's just for getting your brain warmed or it has a special role in the voice circuit?.By the way,if the fan is necessary could you share the buying link?(I´m just replaying so you could pay me attention lol).
The fan is necessary for keeping your helmet visor free of fog. It doesn't contribute to the voice speaker at all.

I used 40mm x 10mm cage fans (https://www.amazon.com/gp/product/B07RMY75GH/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1).
