Dissection: Since we all know I have a history of pulling things apart, I would be letting myself down… so let’s get started! Removal of the passive heatsink is simple. Simply remove the four spring loaded screws from the back of the card. These springs really have no real strength behind them and are kind of ‘just there’ sort-a-speak. With the heatsink removed, you can clearly see the path of the heat pipe, the four mounting points and the base to which the GPU makes contact.   Looking closer, you can see that Leadtek has also included multiple clear rubber mounting feet to help reduce the chance of crushing the GPU and memory. Looking to the channels where the heat pipe is secured, you will notice that there are little silver clips holding the pipe in place. There is no visible soldering or thermal paste used to help dissipation of heat. This seems like an obvious step that was left out of the manufacturing process. Looking at the round copper base, you can see that the thermal paste used for the GPU was plenty in supply and could probably do with a bit less.    Looking at the naked PX7600 GS, you can see that there are a total of eight 32mb Qimonda memory chips labeled HYB18T256161AF-25 SVV01014. These make absolutely no contact with the heatsink. This can obviously make over clocking the memory a little less productive on the stock cooling solution.   Once again, looking at the GPU die, you can see the over abundance of thermal paste. With a bit of cleaning up, you can reveal the markings of a 7600 GPU!   |
