Abstract
A system is disclosed and includes an optical light source to transmit an initial optical signal through a coolant loop, an optical light sensor to receive an initial optical signal response, and in information handling system. The information handling system includes a memory to communicate with the optical light sensor to store the initial optical signal response and a processor to communicate with the memory and the optical light sensor. The processor determines a current optical signal response through the coolant loop and compares the current optical signal response to the initial optical signal response.
