In a market flooded with all in one cpu coolers, it can be over whelming trying to decide what one is right for your system. There are so many factors in take into consideration. What brand, length, width, fin density, pump rpm and noise are just some of the factors one must think of when making a decision. Do you go with an all in one cooler, or go all out with a custom loop? Although a custom loop offers the best performance, putting one together can be intimidating. For this reason, many people steer clear of building custom loops. Is it possible to get the performance of a custom loop, from an all in one? With their 400 watt TDP, EXllusion 240, Lepa may say so. But are all these expandable aio coolers just a fad, or a great way for someone to get into the DYI cooling market?
