Case in point, Cooler Master recently unveiled a huge AIO cooler concept in China, and when we say huge, we mean massive. Cooler Master’s AIO cooler concept defies all traditional norms that we know of a CPU cooler. Instead of a rectangle, the massive radiator is square-shaped, measures 360x360mm, and required four 180mm fans to cool it. For the uninitiated or those who don’t have a passion in DIY PC building, AIO coolers traditionally come in four sizes: 240mm, 280mm, 360mm, and 420mm. Cooler Master said in its presentation that this 360×360 AIO cooler is designed mainly for workstations, and is designed to fit in its COSMOS desktop chassis.
