I have my first Haas complete, and I want additional cooling for the box,
I have the two evercools on the back end of the haas box, and I have
slots cut in the bottom for air to suck into the box... the inlet slots are
cut in the bottom of the hass box.

I plan to mount one or two micro fans (round shape) into a board
using a jigsaw, then I will attach the board to the bottom of the haas
so that the micro fans push air into the slots to allow more airflow
and better cooling.

My goal is to create enough air push to be able to run the evercools
on a lower (quieter) setting.

My question is how can I make these little fans variable speed ??


Thanks
