1. A high-pressure fluid system, comprising:

  • a high-pressure pump;

    a component coupled to the pump to receive pressurized fluid from the pump;

    a temperature sensor attached to at least one of the pump and the component at a location at which a heat flux produced by a leak in the one of the pump and the component can be sensed, wherein the component is a fitting coupling the pump to a tool and the temperature sensor is coupled to the fitting;

    a processor operatively coupled to the temperature sensor, the processor comparing a sensed temperature from the temperature sensor to a reference temperature, and the processor indicating that the one of the pump and the component is malfunctioning when the sensed temperature is above the reference temperature for a predetermined period.
