Has anyone achieved CPU temperatures colder than 15 15 11 11 (C) for a quad core? If so, how did you do it? Is there a a huge performance difference if the system runs colder?
(The temperature was achieved as part of an experiment: http://www.youtube.com/watch?v=21iajieA2WM)
Actually temperatures too cold can get you in cold bug territory and create boot problems until the CPUs heat can offset the cold enough to successfully boot, that's not something you'd want to be experiencing on an everyday basis.
I enjoyed the video thanks, I hope you did take away from it his comment on the condensation he experienced after bringing the computer back in the home, that could have destroyed his computer if he had booted before it had dried out completely, which is one serious side effect of running below ambient temperatures to cool your computer.
His test did yield lower CPU core temperatures but his computer performance only changed 2 points and that little difference could have happened if the test was run a 2nd time before taking it outside the home, so all he got was lower temperature at a cost of zero performance increase.
Unless you are seriously overclocking your CPU and creating excessive heat in the process that needs to be dissipated there's no need for running temperatures that low for a regular computer, as all the computer designs from both Intel and AMD are designed to run in ambient room temperatures.
I personally have run water temperatures down to 8c and depending on the level of overclock that did not translate to an 8c CPU core temperature for sure, but I have been able to boast lower stress test load temperatures than most others Idle temperatures.
That's because I am running
peltier cooling and have been experimenting running
below ambient room temperature cooling for a long time.
But I am an overclocker that runs my CPU all cores overclocked 24/7 you can check my CPU-Z validation to see my present clock if you're curious.

Conductivity of Silicon IMPROVES with heat.
Meaning there is no reason why you would WANT your system to run cooler than actually needed.
You would to cool high overclocks, and for system longevity.
