The forced convection system defines an outer regulated airflow environment between the socket and the liner, and an airflow generation device is coupled to the outer regulated airflow environment and configured to generate airflow therein. A convection control system includes convection control circuitry and is configured to adjust the airflow generation device and configured to dynamically control airflow within the outer regulated airflow environment to maintain negative gauge pressure therein and transfer thermal energy therein to an external atmosphere. The convection control system further includes a rising edge triggered negative gauge pressure regulation device including pressure control circuitry and an associated valve configured to control the first airflow proportioning device to open airflow paths to outer regulated airflow environment. The convection control system is configured to provide regulated differential pressure forced airflow convection to the outer regulated airflow environment with the rising edge triggered negative gauge pressure regulation device.
