Claim 10:
11. An immersion cooling system comprising:
a tank containing a two-phase fluid, the tank configured for immersing an information handling system; and
a temperature monitoring system comprising:
a component surface temperature sensor configured to measure a component surface temperature for a component and generate a surface temperature signal corresponding to the component surface temperature;
a fluid temperature sensor positioned a distance from the component and configured to measure a fluid temperature and generate a fluid temperature signal corresponding to the fluid temperature; and
a processor coupled to the component surface temperature sensor and the fluid temperature sensor and configured to:
receive the surface temperature signal from the component surface temperature sensor and determine a component surface temperature based on the surface temperature signal;
receive a fluid temperature signal from the fluid temperature sensor and determine a fluid temperature based on the fluid temperature signal;
determine a contaminant is present in the fluid by performing one or more of:
calculating a difference between the component surface temperature and the component surface temperature threshold value and determining the component surface temperature exceeds a component surface temperature threshold value,
calculating a change in the component surface temperature over time and determining the change in component surface temperature over time exceeds a component surface temperature change value, and
calculating a difference between the component surface temperature and the fluid temperature and determining the difference between the component surface temperature and the fluid temperature is more than a temperature difference value; and
communicate a signal that residue is present in the two-phase fluid based on one or more of the component surface temperature exceeding the component surface temperature threshold value, the change in component surface temperature over time exceeding the surface temperature change value or the difference between the component surface temperature and the fluid temperature being more than the temperature difference value.
