You would also run two other risks that would scare the heck out of me.
If one or both of your cooling fans can't take the constant running and they fail; or if your thermostat decides to stick closed, your next step is replacing the engine. It will continue to get hotter until the pistons and journals will swell up and seize in their holes causing complete destruction of the engine. At this point its even doubtful that it can be rebuilt since critical parts will have gone way out of spec. You will have just made a boat anchor out of a perfectly good engine
