Liquid cooling distribution in a modular electronic system

A network communication device comprising:

• a chassis;
• a plurality of modules removably inserted into a plurality of slots in the chassis, wherein a coolant is delivered to a first group of the plurality of modules with a first flow control valve in a first cooling loop and the coolant is delivered to a second group of the plurality of modules with a second flow control valve in a second cooling loop;
• a plurality of sensors for monitoring a temperature in the first cooling loop and the second cooling loop;
• and
• a control system for controlling delivery of the coolant to the first group and the second group, wherein the control system controls transmitting a signal to one of the first flow control valve and the second flow control valve to modify a flow of the coolant.
