Installation:
First things first, you will need to remove the stock heatsink from the video card. Then you will want to make sure that you clean the surface of the GPU so that the new thermal grease can work efficiently. Next place a small dab of thermal grease on the GPU die and spread it out thin and even.
 
Now place the screws of the Logisys VGA GPU block through the retention arms and place the block centered on the GPU die. The screws will come through the back of the card. You will then place a rubber washer and the retention “nipple” on the screw.
 
Next you will need to attach the back plate to the retention “nipples” the same way that you did with the GPU block. Looking from the side, you can see that the back place does not touch the video card, but at the same time does not leave any room for anything fun.
 
After you have the GPU block and back plate secured, you will want to place the memory heatsinks on the memory modules. These heatsinks have a double sided thermal tape which allows for easy installation of the heatsinks on the memory modules. During this step, I found that the heatsinks tape did not want to peel, yet decided to give me almost more trouble than it’s worth. I found the secret to getting the film off of the tape is to cut into the corner of the tape with a small blade and then twist and pull up.
  
Now apply a layer of thermal paste to the grooves and the flat surface of the GPU block. This allows for maximum heat transfer from the block to the heatpipes and the cooling plate.
 
Next place thermal grease in the grooves of the cooling plate. The plate then gets placed on top of the GPU block; sandwiching the heatpipes within the grooves. This method is used industry wide and has proven quite effective.
 
After screwing down the first cooling plate, you can see that there is a pretty evident angle on the plate. The angle causes less surface contact and hinders the cooling ability of the unit. We found that this angle was due to the shortened surface due to the length of our AMD x1950Pro video card. One solution for this problem is to wedge something on the far end of the block. All in all, if you have a shorter video card, this won’t be a problem. If you plan on using this unit for a longer card, you may want to carefully screw down the plate to try and get the most level application possible.
With the front cooling plate in place, you can now place thermal paste in the grooves of the back plate and the back cooling plate. Now, at this point, this is where we had run out of thermal paste. We had to substitute with some left over silver thermal grease. Once the grease is applied you can then attach the back cooling plate.
  
Now that you have both plates attached, you can now add the top retention braces and the top fan. To do this, you will place the retention screws within the slots in the cooling plates, then attach the brace or fan, then place the nut on the top.
