Back To Basics On Cooling

At least in Europe, the summer wasn't really all that warm (Ed.: Yeah, try living in Bakersfield, CA). But for a PC owner or do-it-yourself builder, the issues of waste heat, cooling, and ambient temperature are always worth thinking about. That's why we're going to start at the very beginning in this, our introduction to cooling. Every year we have new readers, and every year we see some of the same questions posed in our forums. The very last thing we want is for an expensive project to fail as a result of a mistake made in the most basic tenets of keeping hardware running at acceptable temperatures.

Because the topic is extensive, and because we want to offer a comprehensive tutorial, we'll present the whole story in two parts (the second of which will appear next week).

So, first we'll talk about the best sort of chassis, including the mounting location of the power supply. Then, we'll take a look at the potential drawbacks of other solutions. Optimized airflow is the most important consideration in an air-cooled system, so we plan to go into a lot of detail on that. Then, we'll take a look at classic case fans, and show why even a beginner doesn't need to be afraid of applying thermal paste. If you also bear in mind the importance of having space between your multi-GPU configuration and understand why the often-maligned side-panel fan can be useful, your PC will be better-equipped to survive next summer's heat.
