The HR-03 VGA cooler delivers outstanding performance when used with a fan and can still provide very good cooling when used without a fan in pseudo-passive mode. The HR-03 should really appeal to anyone looking for a quiet cooling solution. The overall construction and build quality of the HR-03 is excellent.  And the ability to mount the HR-03 heatsink on either side of the video card provides a lot of flexibility and helps make the best use of available space.


I especially like the pseudo-passive configuration.  Positioning the HR-03 heatsink in the airflow path of a nearby CPU cooler or existing case fan allows it to perform extremely well without requiring an additional fan.

  • Outstanding cooling performance
  • Very good build quality
  • Easy installation with two flexible mounting options
  • Silent operation when used in passive mode without a fan
  • Very quiet when used with a low speed fan
  • Designed to directly mount an optional 92mm fan



  • Relatively large size may be an issue in some installations
  • Limited compatibility (check Thermalright’s website for updates)

The Thermalright HR-03 is an excellent cooling solution for today’s hot GPUs and features outstanding thermal performance, flexible mounting options, and the ability to run in passive mode without adding fan noise.
