Fans of high-quality PC components are aware of the Japanese brand name Scythe for a long period of time. Scythe is especially famous for high performance CPU coolers and super silent fans among pc enthusiasts. Its Katana series is one of the oldest series, which now receives a major upgrade. Throughout the Katana series its tilted fin and heatsink design was sustained and was a key design-element. Fourth generation of Katana CPU cooler keeps the tilted design in the new and modern fin structure, which increases the overall performance of the aluminum heatsink.

Another advantage of the new design is the option of mounting an additional fan to improve performance or reduce the total fan speed as well as noise level. Supplied fan is able to operate at a speed range between 300 and 2.500 rpm. Hence allows users to utilize the Katana 4 CPU coolers fan speed for silent or preferment operation for overclocked CPUs. Total height of Katana 4 equals to the predecessors 143 mm, which enables a high compatibility to almost every PC case throughout the market. Furthermore total of 3 heatpipes are being adopted from the predecessor. To assure fast heat transfer a copper base plate is being used which is nickel-plated in addition.
