...yeah.
Thinking about taking a few concepts to cooling a computer.
I have seen sanitizing done with two very close frequencies, which creates "pockets" of extreme heat and pressure.
The thermoacoustic module uses extremely low frequencies contained in a large metal housing to cool newer refridgerators without harmful refridgerants or anything of the sort.
Just thinking of a way to create a box that would be mountable to a heatsink with two small speakers. Experimentation ^^
