Scythe SCKTN-4000 92mm Katana 4 CPU Cooler

Well known for its' reliability and its curved fin structure Katana 4 has a long history of cooling. The 4th generation stands out with its new, modern design combining key features of previous versions with design and efficiency improvements. The low height as well as the structure of the fins and the use of three heatpipes are adopted from its' predecessors. In addition, the new design lays the foundation for higher cooling performance by providing larger cooling surface and the possibility to mount a second fan. The Katana 4 is equipped with a 92 mm Slip Stream fan operated by the PWM signal of the mainboard, circulating at 300 to 2500 rpm. This combination enables virtually silent mode as well as overclocking, by providing sufficient cooling resources for almost all environments. The Katana 4 is compatible with all current sockets.

Compatibility
Intel:
Socket LGA 2011 / 1366 / 1156 / 1155 / 775

AMD:
Socket FM1 / AM3+ / AM2+ / AM3 / AM2 / 940 / 939 / 754

Improved Performance
Higher cooling performance is one of the characteristics of 4th generation Katana CPU cooler. The combination of 3 heatpipes, large fins and a PWM-controlled Slip Stream 92 mm fan ensures high-scale heat dissipation. A slightly angled fin structure, allows the airstream to hit the surface directly. Overall surface of the heatsink has been increased.

Compatibility
As it is common practice for all Scythe products, Katana 4 provides maximum compatibility. All current sockets are supported. Furthermore, a new generation one-touch clip system is launched with Katana 4 excelling in user friendliness and durability.

New Look
To be released in a completely new design, Katana 4 provides a new, modern look. The fan is situated right-angled to the motherboard and fins are tilted downward. Heatsink and Heatpipes are completely redesigned. Optical enhancements go hand in hand with practical improvements. Better cooling performance is one of them.

Compact Design
The bias of the new design originates in one simple question. How to build a new, modern looking Katana-style CPU cooler, without sacrificing the compact dimensions of its predecessor? Katana 4 transports this idea into reality. The measurements are very similar to Katana 3, allowing, as before, the use in limited space environments.
