"The US Patent & Trademark Office published a patent application from Apple that revealed their intent to reinvent an ionic wind generator cooling system. This type of cooling system doesn’t use a fan or heat sink. The problem with the current design however, is that it’s only able to cool limited areas within a computer or device. Apple’s reinvention of the ionic wind generator will allow the system to use specialty sensors and mechanisms to redirect cool air to various areas within a computer or device, as needed."
