Gateway is it wise to be running temps over 100c (ie. boiling point) in a closed loop water cooler? I've got my boards at 99C overheat.
The temperature is measured at the chip, so it is highly unlikely that the actual water temperature is 100°C when the chips says 100°C.
However, you shouldn´t need to worry if you get a good enough pump and high cfm fans on the radiator.
