The cooler makers often prefer to modify and enhance the already existing products. Far not every manufacturer and way not always manages to design a cooler with well-balanced cooling efficiency, acoustic characteristics and price on the first attempt. Moreover, modifying an existing product is always way cheaper than developing and launching into production a completely new model. The release of new CPUs and graphics cards works as an additional stimulus (and sometimes as a necessity) for launching new cooler revision, because they may use different mounting holes or new PCBs that are incompatible with existing cooler systems.At the same time, it is fairly hard to consider the two new coolers, which we are going to discuss today, slightly modified products. Arctic Cooling Accelero Twin Turbo Pro and Scythe Setsugen have been altered significantly compared with their predecessors. Therefore, we believe it makes more sense to regard these products as another phase of evolution in the cooling solutions market. Well, let’s see how successful this phase turned out to be and if Accelero Twin Turbo Pro and Setsugen can cope with contemporary graphics accelerators without hurting the users’ ears too much.
