The Inte i9 is THE latest thing, so very recently released that we only have sketchy information from those who managed to get to see it. Apparently th chip gets very hot. To demonstrate its amazing clock speed on challenging its limits at exhibition, two professional overclockers very carefully used liquid nitrogen to cool the chip.
To reach these clock speeds on all 8 cores as the i9 did on demonstration, liquid helium is necessary to cool the chip and this seems likely to remain the case for all in its last.
Overclocking is the process by computer developers to be able to stack all of the hardware that they can into one device in order to get the maximum amount of processing speed. When a computer is larger and has more processing capacity, more fans are needed in order to cool down the computer. Fans can be found on all computers and they are there to cool down the computer. With space very small in a very overclocked computer, liquid helium is able to get into all of the spaces inside of the computer so they all will be assured of being cooled down. With all of the parts of the hardware being compressed so tight, a regular fan miight not be able to adequately cool down the parts. Liquid helium can be able to cool down the parts and that is the reason that the Intel i9 processor and hardware setup uses liquid helium.
