Scythe Andy Samurai Master 6 Heatpipe CPU Cooler Review

Manufacturer: Scythe

Features and Specifications

The Scythe Andy Samurai Master is a large, down draft style CPU cooler that incorporates 6 heat pipes and comes bundled with a 120mm low speed fan that is very quiet.  The Andy Samurai Master (ASM) includes tool-less mounting hardware that supports the majority of Intel and AMD platforms.  Scythe had very good success with their previous Infinity and Ninja CPU coolers, which are both large tower-style coolers that use horizontal airflow.  The ASM is designed for users who want a down draft (vertical airflow) cooler that can keep their CPU cool along with helping to cool other components on the motherboard in the CPU socket area.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />



Scythe has a well-earned reputation in the computer industry for innovative and unique designs.  They specialize in high performance products for PC enthusiasts in gaming, overclocking and low-noise arenas.  Scythe’s main headquarters and manufacturing facilities are located in <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Tokyo, Japan with a Scythe USA sales and distribution office in Torrance, California.

Heat Pipe Technology


The Andy Samurai Master HSF uses six copper heat pipes to transport heat from the heatsink base up into a large array of interleaved aluminum fins.  A heat pipe is a highly efficient conductor of heat.  A properly constructed heat pipe has a very low thermal resistance, which is roughly independent of its length (unlike ordinary metal rods whose thermal resistance increases with length).  Heat pipes are commonly used to transport heat from one location to another.




Heat pipes work on the principle of evaporation and condensation.  A working fluid (frequently distilled water) evaporates inside one end of the heat pipe (the hot-end) absorbing heat in the process.  A partial vacuum inside the heat pipe allows the water to evaporate at low temperatures.  Once formed, the water vapor diffuses from an area of high vapor pressure (where it is being generated) to the other end of the tube where the vapor pressure is lower.


The vaporized fluid then condenses back to liquid (cold-end) and the heat is dissipated into the air from the metal cooling fins.  The working fluid returns to the hot end via capillary action thru an internal wicking structure (sintered metal coating, fine wire mesh, or grooves) so the heat pipe does not have to rely on gravity to recycle the working fluid.  The key to a heat pipe’s high efficiency is the latent heat of vaporization. 


The Scythe ASM CPU cooler comes securely packed inside a colorfully printed box, along with everything needed to install the cooler on most any modern Intel or AMD platform.
