According to one embodiment of the invention, a method for preventing the failure of a system, which includes one or more pipes, or one or more cooling jackets, or one or more fluid cooled system components carrying a fluid, involves detecting one or more pressure levels of the fluid in the one or more pipes at one or more points, then comparing the detected pressure levels to a corresponding one or more predetermined limitation values. If the detected pressure levels exceed the corresponding limitation values, a shut-down signal is generated. The shut-down signal triggers the adjusting of one or more systems responsible for causing thermal variations of the fluid, preventing the system from failing while allowing the system to continue operation shortly thereafter.
