Installation:

Removing the factory heatsink and fan shroud from a graphics card is generally a simple process, although it may seem intimidating to a novice. The process is actually simple if you follow the directions and take certain precautions in regards to static electricity. Wearing an anti-static wristband is recommended to help control static discharge. Also, you should always shutdown your computer and remove the power cable before attempting to work on it.

Today, I will be installing the Twin Turbo on a graphics card in dire need of aftermarket cooling - a reference model ATI HD 4850. With GPU idle temperatures in the mid-70s at the factory frequencies, the 4850 is a prime candidate for the Twin Turbo.  Installation of the Twin Turbo is very simple.

All of the 4850's mounting hardware is found on the opposite of the PCB that the fan is on. There are 8 screws going directly into the PCB and 4 holding the backplate in place. Start of by removing all of these screws and lifting the fan-heatsink assembly away from the graphics card. Once this is finished, the 4850 will be completely bare. Next, clean the factory thermal paste off of the GPU and install the memory and voltage regulator heatsinks. Also, Arctic Cooling's website mentions that a heatpipe might interfere with the installation of the upper-most memory heatsink on a 4850. This was not an issue for me, but Arctic Cooling suggests offsetting the memory heatsink to allow clearance.

 

 

 

 

 

 

 

Now, lay the Twin Turbo upside down on a flat surface. Install the four cylindrical white washers on the sticky portion of the heatsink retention bracket. Note that the retention bracket has two sets of holes to accommodate a variety of video cards. In this, I used the outer set of holes for the 4850.

 

Next, lower the video card on to the Twin Turbo heatink base, until it rests gently on the GPU. Install the four red washers and 4 screws through the PCB and into the heatsink base. To finish the heatsink install, plug the fans into the socket on the video card.

After installing the 4850 back on the motherboard, you can see that there is just enough room to fit a graphics card into the second PCI-E x16 slot.
