Abstract
An apparatus is described. The apparatus includes an electronic system having a printed circuit board with electronic components mounted thereon. At least some of the electronic components are coupled to components of a liquid cooling system. The electronic system has a light source and a photosensitive element. The light source is to illuminate an illuminated region of the printed circuit board and/or at least one of the electronic components. The photosensitive element is to detect a change in reflection from the illuminated region in response to the presence of coolant that has leaked from the liquid cooling system within the illuminated region.
