Overclocking

[Glordit]

If you want to play around with high clocks for short(ish) amounts of time - i saw some ppl using one of the closed loop WC systems with the radiator fan detached and the radiator immersed in a bucket of cold water. (apparently adding salt to the cold water also helps cooling further)

Would not recommend using salt in any PC water cooling systems. While salt water is a better conductor of heat it is more likely to cause calcification and corrosion.
