ProCooling have a rather interesting article which explains four different cooling technologies - Phase Change, Water, Hybrid and Air cooling. They say it took them over a month to write with research included, I'd believe it.
Welcome to one of the first breakdowns of the 4 main cooling technologies in use to cool computers. In this article the ProCooling team took different parts that they have the most experience in and break down the technologies into the basic principles behind them. This is not an over the top physics class type article, this is meant to help you understand what the deal really is with these cooling systems. This will also break down a few very common misconceptions about cooling systems.It is well worth the read, good job guys.
