a first flow sensor to sense a flow rate of liquid coolant flowing through a first line having a first pump to push liquid coolant into an information technology (IT) enclosure that includes at least one electronics board;

a second flow sensor to sense a flow rate of liquid coolant flowing through a second line having a second pump for receiving liquid coolant from the IT enclosure;

a third flow sensor to sense a flow rate of liquid coolant flowing through a third line having a third pump to receive liquid coolant from a coolant source, wherein the liquid coolant drawn from the first line is received from at least one of the second line and the third line, wherein the first, second, and third lines are fluidly coupled together at an intersection such that the liquid coolant can flow between the first, second, and third lines; and

a controller to receive sensor data from each of the first, second, and third flow sensors and to control pump speeds of at least one of the first, second, and third pumps based on the sensor data.
