The potential issue for new water-cooled systems is that they are going to be customer installed. This is unlike existing water-cooled systems which are installed by service personnel, which allows for control and verification of the water type and quality entering the system. There is a concern that, on the new customer-installed systems, some customers may use tap water rather than the recommended deionized (DI) water or BTA-treated water. A customer may do this to save cost or because they are unaware of the problems that can result from using tap water in a system. Using tap water without BTA in a water-cooled system can lead to corrosion and build-up of calcium deposits, ultimately costing money in increased service calls, repairs, and warranty claims. Since using service personnel is not an option for these lower-end systems, a solution to detect if customers are using tap water, notify customers and/or the service provider if tap water is used, remind them to use DI water or BTA, and track reliability concerns is a more acceptable solution.
The main point is the incorporation of a water conductivity and BTA sensor into the inlet of a water-cooled system to determine if a customer is using untreated tap water rather than deionized/BTA water, as recommended. This sensor controls a valve to said system. If tap water without BTA is detected, then the valve to the system will not open, and the customer will receive a notification that they should use deionized/BTA water. The notification would protect customers if they use a service to manage their systems. If a customer overrides the valve, a message could be sent to the service center to notify them of a warranty violation, decreased reliability of their system, and the potential for future reliability issues.
