| Sapphire Atomic Radeon HD4870 X2 2048MB Graphics Card
|
The Basics (continued):
An end view of the card is provided in the below left image where we see that there are two PCI Express power connections (one 6-pin and one 8-pin). There is also a 4-pin header that seems to be unused. Perhaps this is a fan header for a version that is not liquid cooled?!?
 
The above right image takes a look at the card from the other end. There are two DVI connections straddling a single TV-out connection, and considering all of the adapters included you should be able to connect to just about any type of monitor. There is also a single CrossFire tab, meaning you can connect to one other card for even more multi-GPU muscle!
The below left image takes a closer look at the liquid cooling fittings on the edge of the card, while the below right image shows the item at the other side of the circuit. A black radiator equipped with a 120mm fan handles the heat exchange between the liquid and the air. Both the radiator and the fan feature Sapphire Atomic markings, and the fan lights up with blue LEDs when in use.
 
The final item to inspect is the CPU water block. It features a cylindrical chrome body that houses the pump, and the surface that mates with the CPU is copper. Thermal paste has been pre-applied by Sapphire, and a clear plastic cup is used to protect it prior to installation.
 
The edge of the water block looks like a gear, and this is how the cooler is held in place. The retention brackets have a mating surface that will lock onto the cooler's edge, and as you tighten it to the motherboard it will apply pressure between the copper surface and the top of the CPU. It seems like a simple enough idea, but I hope it is sufficient for a solid connection and good heat transfer.
