For overclockers who really want to get an extra punch out of their GPU.. a stock cooler doesn’t usually do it justice. Copper Heatsinks are becoming more and more popular, and Logisys has joined that bandwagon. Does their Copper cooler improve on a stock cooler?
To test the performance, I used a variety of different programs. The overclocking tool I used is ATI Tool, which is how I detected the maximum ‘Safe’ overclock. Below are the results of all the overclocking tests.
In the graph, Max Overclock can be translated as Asinine Overclock, as it’s not always the safest thing to do on air. The stated overclocks is where it starts to show artifacts during 3D rendering. If I begin to see numerous artifacts, I have gone to far. So remember.. max overclock is where I seen the rare Artifact.
For benchmarking, I used Futuremarks 3D Mark 2003 and 2005.
As you can see, the benchmarks overall are better with the Copper cooler. For the most part, each test with the maximum overclock, increased it by 200 Marks. Not an extremely impressive result, but one thing I did notice, is that things seemed a lot more stable. With the stock cooler, there were more artifacts on screen during the tests, than with the Copper cooler.
I was not able to provide graphs with temperature changes. My ATI control panel used to display temperatures, but has not for the past while, for unknown reasons. However, since using the Copper cooler, my overall case temperature has gone down a few CÂº. Nothing amazing, but definitely welcomed.
