TweakTown has just posted a new guide entitled "Heatsink Theory Guide", which gives us a run down of the theory behind heatsinks. Here's a snip:
"There are many different heatsink fan products on the market today with the rise of overclocking popularity over the past few years. Heatsinks come in all different shapes and sizes are made out of a range of different materials. We have different fan choices, from the ultra quiet mildly performing to top performing of the range highly performing noisy fans. But in the end, I'm sure you've all wondered before now, "how do they actually work?". In this guide TweakTown tells us just that, the theory behind heatsinks."
