HotHardware.com posted a new article in which they experiment with Liquid Nitrogen overclocking.
In order to push the limits of the 975, we decided to leave the safe confines of air cooling and enter the precarious world of sub-zero chilling. Liquid nitrogen, or LN2, is commonly used as a coolant within the overclocking scene and can reach much lower temperatures than air, water, or the phase change cooling you may be accustomed to. While we are used to seeing processors operate in air-cooled settings of around 40'C, the use of LN2 will allow us to push clock speeds all the way down in the -80'C range in order to unlock the overclocking capabilities of both the motherboard and CPU. We paired a Core i7 975 processor with the EVGA X58 Classified motherboard to find out just how far we can go with the X58 platform and Intel's current flagship CPU...Core i7 Extreme Overclocking with LN2
