A printed circuit board assembly (PCBA) positioned in the sealed enclosure. The PCBA includes one or more major electronic components and one or more minor electronic components. At least part of a cold plate is positioned in the sealed enclosure, is thermally coupled to the one or more major components, and is at least partially submerged in the immersion cooling fluid.
