OCIA.net has posted their review of the Thermalright HR-03 GTX

It was nearly a year ago when we reviewed the HR-03 GT from Thermalright. At the time, the GT represented Thermalright's latest and greatest video card heatsink, made to cool the latest and greatest offerings from nVidia and ATI, namely the GeForce 8800/9800 G92's and the Radeon 3850/3870 RV670's. Then in June/July nVidia and ATI released new flagship cards based off the GT200 and RV770 cores. However, aside from some early water block releases there wouldn't be an aftermarket cooling option for the GTX for months to come. But Thermalright was not willing to let their loyal fans down, and based on customer demand they have developed the all-new HR-03 GTX cooler. This represents the first and only aftermarket air cooler for the GT200 series cards that I am aware of.
