You probably already saw some extreme cooling overclock videos out there.
This one, using liquid helium on an AMD Phenom II processor beats the 3DMark06 world record with speeds over 7Ghz!

Ok, so maybe you understood nothing of what I just said.
It’s basically a computer reaching extreme speeds by using extreme methods to keep the processor cool.
If you’re not nerd enough to get this video, at least this may serve as a lesson to people in the advertisement industry: Leave it to a big ad campaign to turn nerds doing an otherwise extremely boring task to turn it into something very awesome. xD
