Cooler Master Hyper 6+ Heatsink Fan

Introduction

Cooler Master has just introduced a new version of the popular Hyper 6 heatsink fan (HSF).  The Hyper 6+ is even bigger than the original Hyper 6 but weighs slightly less thanks to the use of aluminum fins (the original Hyper 6 used copper fins).  It stands a full 146mm (5-3/4') high and weighs in at 800g (28 oz) not including the fan or mounting hardware.  <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />


 



 


The Hyper 6+ incorporates six heat pipes to transfer heat out of the copper base into a large array of aluminum fins and comes with a quiet 100mm fan, which can be mounted on either side of the cooler.  An optional second fan can be used if desired.  The Hyper 6+ uses a universal mount that supports the latest Prescott LGA775, Pentium 4, AMD K8 and K7 processors.


 


Key Features:



  • High performance cooler — Ultra quiet

  • Six imbedded heat pipes provide superb heat dissipation

  • Special heatsink design — maximum cooling performance at any mounting angle

  • Raised base design to avoid interference with surrounding components

  • Special welding techniques enable seamless connection between fins and heat pipes

  • High-density fins provide a large surface area for heat dissipation

  • Greater cooling performance with optional high speed 100mm fans

  • Universal mounting hardware for all P4, K7, and K8 platforms

Heat Pipe Technology


 


The Hyper 6+ cooler uses six copper heat pipes to transport heat from the heatsink base up to the large surface area provided by the 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.  One gram of water absorbs 540 calories of heat when it changes state from a liquid to a gas (without any increase in temperature).  It then gives up this same amount of heat when it condenses back into a liquid.  By contrast, adding 540 calories of heat to 100 grams of copper (small heatsink) would raise its temperature 60ºC!
