Hi,
The system pumps fresh cool dielectric to each component on the server as required, in a precise, engineered way to keep the component within design specification. Each server is individually flashed with new firmware to remove errors related to fan RPM. Worth also mentioning that the pumps used also provide similar data to fans, RPM etc. The health of the system is measured very precisely and can all be monitored remotely. I am talking from experience designing and using the system.
