A liquid cooling leak sensor unit for an information handling system includes a cold liquid reservoir, a non-conductive material, a rigid conductive component, a wicking material, and a leak sense controller board. The non-conductive material is in physical communication with the cold liquid reservoir. The rigid conductive component is in physical communication with the non-conductive material. The wicking material is in between and in physical communication with both the cold liquid reservoir and with the rigid conductive component. The wicking material transfers liquid from the cold liquid reservoir to the rigid conductive component. The leak sense controller board is coupled to both the rigid conductive component and the cold liquid reservoir. The leak sense controller board detects a leak in the cold liquid reservoir in response to an electrical change between the rigid conductive component and the cold liquid reservoir.
