how long is a piece of string?
overclocking is not a science, nor an art. it's pure luck. there's no way to guarantee a certain overclock out of any particular chip, nor is there a defined limit on how far a particular chip would go.
temperature is a contributing factor, but not the only one. plenty of people use thermo-electric devices called peltiers combined with water cooling to get their chips down below zero degrees C. there's even a handful of crazy overclockers (most of which bizzarly seem to come from japan) who use liquid nitrogen to cool their machines down way below freezing temperatures. even with these temps machines will top out at 4 to 4.5GHz.
a CPU is a device with a bucket load of tiny little gates in it. electrons whiz about these gates in a certain fashion to come up with what you and i eventually percieve as logical data. if for any reason a single electron happens to be in the wrong spot at the wrong time, we get errors, system crashes, blue screens or even worse: damage to our CPUs.
there's only so far a certain architecture will allow a certain type of CPU. you can't just go and grab an old 386, cool it to -100 degrees and expect it to run at 2GHz, it just won't happen.
remember also that you cannot cool a system further than the substance you are using to cool it with. if you are runnign 20 degree water through a water block over a CPU, the CPU won't magically cool to 5 degrees.
5 degrees through water cooling would probably come from pre-chilled water, which costs money to chill. not to mention that if any particular thing is cooled artificially, then there's got to be something else heating up to compensate (go and check behind your refridgerator and see how hot it gets back there).

Just on a freezing note, did anyone happen to read the article about the scientists that recently won the Nobel Prize for their work in quantum mechanics? They were studying the effects of electrons and other such atomic particles at near absolute zero temperatures and discovered some quite amazing things in terms of conductivity.... "super conductivity."... imagine the possibilties..... :scream:
