A method, apparatus, and system are described for an ionic wind generator. The ionic wind generator may have a first electrode that is elevated off a surface of a device that the ionic wind generator is intended to cool. A first surface of the first electrode is in contact with a first surface of a first post that elevates the first electrode off the surface of the device that the ionic wind generator is intended to cool. The ionic wind generator causes a generation of ions that are then drawn through an interstitial atmosphere from the first electrode to a second electrode to affect a velocity of local flow over the surface of the device between the first electrode and the second electrode. The flow from a forced flow device also affects the velocity of local flow over the surface of the device between the first electrode and the second electrode.
