Abstract
A method and apparatus for lowering integrated circuit chip ambient temperatures uses negative pressure to induce cooling liquid flow, rather than prior art positive pressure approaches, thereby preventing undesirable cooling liquid leakage outside of the cooling region. The cooling liquid is deaerated to eliminate performance degrading air bubbles, which are a by-product of the negative pressure approach.
