Installation

I'm installing the CoolViva on my GeForce 6600 based card. It is similar to the 6600GT chipset in that it uses the four mounting holes around the die and has four DDR3 memory BGA chips arranged in pairs above and to the right of the core. Due to this configuration it is impossible to install memory sinks on the top two chips, this is an issue I have run into previously with other graphics coolers. Since I could not use two of the sinks I elected to leave all four uncovered and just install the main cooler. There are four posts that thread into the mounting plates on either side of heatsink base. These posts then fit through the holes in the card and are secured by screw-on caps from the other side. Plastic washers prevent contact with any board components around the holes and springs attached to the bottom of the caps help keep the proper tension of the heatsink against the GPU core.



The CoolViva appears to be quite large once installed. The heatpipes and aluminum fins extend far above the height of the card. The fan and plastic shroud extend outward from the card enough to clear all the caps and other board components, however this will likely intrude into adjacent slots on the motherboard once installed. The power header on my video card only offered a 2-pin connector, so I had to use the included adapter to connect the fan to an available Molex. By using the adapter you lose the ability to monitor fan speeds.
