The massive cooler sports 5 heatpipes that travel through all the heatsink and are being cooled with the help of the 3 PWM controlled fans; the 3 fans are connected together so they run at the same speed at all times, and are powered from the same onboard connector:

From both sides of the PCB, we can see a large aluminium plate that covers the VRM, and helps it cool more efficient:

On the opposite side of the heatsink, we can find another Calibre brand logo:

In the top right corner, we can find one six-pin power and one 8-pin PCIe power connector:

If we look between the heatsink and the PCB, we can discover the large plate that covers the GTX 580 GPU:

On the back of the PCB, we can discover that the cooling solution is longer that the card itself:

The VRM heatsink is kept in place with small screws and plastic washers, to avoid scratching the PCB surface:

The card also have some unused holes, coming from the stock cooling PCB design:

The main heatsink is fixed with the help of 4 screws loaded with springs:

In the VRM area, we can also find some stickers representing the card serial numbers and the firmware version, helpful for the engineers when the cards comes to service:

On the I/O shield, we can find two DVI connectors and one miniHDMI:
