Introduction and Features

The new HR-03 VGA cooler is modeled after Thermalright’s classic XP-120 CPU cooler and delivers outstanding performance. It features two flexible mounting options and can even be used in a passive, fan-less mode.

The HR-03 video card cooler features classic Thermalright construction and incorporates four heat pipes to efficiently transport heat from the copper base into a large array of aluminum fins.  The HR-03 is designed to work with both ATI and nVIDIA video cards and can be used with or without a fan.  It can be mounted in either of two ways, with the cooling fins on one side of the video card or the other, to better utilize available space.  The HR-03 builds upon Thermalright’s successful V-1 Ultra VGA cooler and promises even greater performance.

The Thermalright HR-03 heatsink can be used with a 92mm fan of your choice or it can be used in passive mode without a fan.  In many cases, the HR-03 will perform very well in pseudo-passive mode, when using the airflow generated by a nearby CPU cooler or case fan.


HR-03 Features and Specifications:

  • Designed to work with or without a fan
  • Passive cooling delivers silent operation
  • High performance and low noise when used with a fan
  • Copper base, multiple heat pipes and large fin area for optimum heat transfer
  • Proprietary fin design for efficient ventilation
  • Two ways of mounting cooler for best space utilization
  • Light weight and easy to install
  • Both ATI and nVIDIA platforms supported
  • Wire clips for directly mounting an optional 92mm fan


The good folks at Thermalright also sent along a syringe of their new Chill Factor thermal compound.  It features an environmentally friendly formulation, which is easy to apply and is non-electrically conductive.
