Claim of US Patent No. 10,194,562

1. An information handling system comprising:an information technology node including a heat-generating component;
a liquid manifold in thermally-conductive contact with the heat-generating component;
a valve to couple facility cooling water to the liquid manifold;
a first temperature sensor to provide first temperature information specifying a temperature of air entering the information handling system;
a humidity sensor to provide humidity information specifying a humidity of the air entering the information handling system;
a second temperature sensor indicating a temperature of the facility cooling water; and
a processor configured to:
determine a dew point temperature based on the first temperature information and the humidity information; and
activate a condensation mitigation procedure if a difference between the temperature of the facility cooling water and the dew point temperature is less than a first threshold value stored at the information handling system, the condensation mitigation procedure to reduce a flow-rate of the facility cooling water to the liquid manifold using the valve.
