When you OC with Liqiud freon there is really no danger unless your moron and increase the core voltage to 1.90 and try and overkill the cpu. Other than that it \'s all good, though you must know what your doing, or else you asking for a real mess. Also in order to run my Vapochill unit and water cooler for my graphics card I have 550Watt enermax power supply unit. I have temp cpntrol on everything, it\'s great and the investment is well worth it. Think about it, you buy a 2.5 ghz cpu whic can be pumped up into the 3.4-3.6 ghz range. Already you have a cpu faster than any consumer cpu on the market also the unit is versatile, in where the clamp piece can be changed for future cpu upgrades.
