Aspects of the disclosure provided herein generally relate to a fluid flow network configured to cool subsystems of a substrate processing system. Aspects of the disclosure provide a fluid flow network and method that adjusts the flow of the cooling fluid through each subsystem of the substrate processing system. The methods described herein can include maintaining a flow rate of the cooling fluid through each subsystem over a range of cooling fluid pressures. The methods described herein can further include configuring the fluid flow network to equalize a flow rate of the cooling fluid through similar subsystems such that the flow rate through each subsystem is similar without adjustment.
