I should have been more clear in my diagram that I was pondering a block with the transducer inside of it, not on the outside. As for the electrostatic idea, that is interesting also, but it would be hard, if not impossible to implement it in a water cooled environment since it would be near impossible to find a cooling solution with a high enough dielectric constant while maintaining the positive cooling attributes associated with water. In both situations, the question of impact upon the electronic functionality of the CPU while either being bombarded with piezoelectric induced energy, or high voltage fields in the case of the electrostatic approach, remains to be assessed.
