Here we see the Molex connector up-close. You hook it up to your power supply. Something that will likely be gone with PCI Express next year.
Some extra photos to show PDF cooling a tad better.
Here we can notice the LCD screen that will read out the GPU temperature and RPm of the active fan.
The card is not a 'closed' system. When we look at the bottom you can easily look into the 'interior'. The idea of PDF basically is to shield the card from outside heat from for example a PCI card. That idea works though as the measured temperature never exceeded 44 Degrees C.
