Dismantling The Card
We dismantled the cooler to have a look under it, as well as to allow us to closely inspect the heatsink design and fan. It wasn't very difficult. In fact, there were only four screws to remove and voilà! the cooler popped off!

The card... in the nude! |
As you can see, the cooler is quite small. The card itself is pretty plain, populated mainly by the GeForce 7900 GT GPU and eight GDDR3 memory chips. The GPU itself is covered in thermal paste.
Here's a closer look at that GPU. Doesn't look like much, all smudged up in thermal paste, but that's the spanking new GeForce 7900 GT right there.

The other two pictures show what the GeForce 7900 GT will look like from the top and bottom, without the thermal paste, of course. 
The Fan
The cooler is powered by a single Protechnic Magic 50mm fan placed to the right side of the cooler.
According to Protechnic Electric's specifications, this is a high speed fan with two ball bearings and a power output of 2.28W. Oddly, there's a slight discrepancy between the rated current on the top label and the actual fan label.

The fan |
Label on back of fan |
This fan spins at 6,200 RPM and is rated with an air flow of 13.61 CFM or 0.386 CMM. It has a noise level of only 36.5 dBA and comes with automatic restart and locked current protection features.
Although the fan is not a blower fan, it acts as a blower, thanks to the design of the cooler and the shroud. Cool air is sucked from "above" the cooler and hot air exhausted out the top and the left side of the cooler.
