It seems to me that not too long ago I can remember clocking the snot out of my ATI X800 series cards. Soon after very limited clocking, I realized that the stock “boomerang” cooler on my X800 GTO wasn’t going to do the job. So off to the forums I went for advice. At the time I was directed to the VF-700 and VF-900 cooler from Zalman. Now, I can remember that there was a pretty significant drop in temperatures with my first VF-700 that ran me about $30. A bit later I got my hands on an X850 XTPE and learned how to voltmod. What came next was the need for a better cooling solution, so I opted to get a VF-900 for around the $50 mark. The cooler was good, but still not what I was looking for.
