De mannen van Firingsquad hebben een artikel online gezet over de natuurkunde achter heatsinks. In het artikel wordt uitgelegd op welke manieren warmte kan worden overgedragen, en welke factoren invloed hebben op de warmteoverdracht. Onderwerpen zoals materiaalkeuze, kleur en airflow passeren allemaal de revue. Wellicht een interessant stukje tekst voor de tweakers die vroeger bij natuurkunde het liefst sliepen :
As processors continue to up the ante on clock speed, a greater amount of heat is generated. Factors such as die shrinks and reduced power consumption help to keep the temperatures tame. On a far more obvious level, one can also see that heatsinks have progressed substantially from their humble days. A scant three years ago, most CPUs had tiny hunks of metal, with an equally tiny fan attached to it. If you wanted to increase your chances of a substantial overclock, it was time to change the fashion statement of your computer from drab beige box to au natural, it also wouldn't hurt to bust out a table fan.
In a relatively short span of time, computer cooling has stepped from the stone-age into the err… the iron-age (well we're still using hunks of metal with fans on them and most computers still tend to be naked). Entire websites and companies have come to fulfill an overclockers' wet dream. Everything from thermal grease, to 7,000 RPM fans are offered. Heatsinks varying in size, shape, and composition, provide computer users with an even greater level of choice when it comes to cooling their little pets.
We aren't going to discuss any particular heatsinks in this article. This article will cover many of the principles behind heatsink choices. There are quite a few physics concepts behind all these hunks of metal, things "with alloys and compositions and things with ... molecular structures".
