It seems that every overclocker today is worried about temperatures today. Go to half a dozen or so overclocking sites, and the most common topic discussed will be heatsink fans, blowholes, cases, RAM heat spreaders, etc. Is that really necessary? I mean does all this worry about temperatures really amount to something? Or is it all a bunch of hot air (sorry couldn't resist)..... Ironically, there is very little scientific information released on this subject, even at the so called "expert" overclocking sites. In this article, we will try to explore the affects of temperature on hard drives and CPUs, as well as try to offer a little theory behind the relationship between temperature and reliability.
