Installing the VF1 is tedious but not difficult so long as the instruction manual is used to identify which parts belong where. The whole process takes a while, as the fan requires some assembly as well.

Three pairs of mounting clips are included, allowing the VF1 to be mounted on as a wide range of cards as possible. Only a single range of cards is incompatible: The Geforce 7800 GS AGP series. Two other specific cards are listed as incompatible: The EVGA GeForce 7800 GS CO Superclocked, and the Asus Radeon A9600GE. All other recent ATI and nVidia-based cards should be compatible.

The first step is to install the ramsinks, as the RAM chips are inaccessible once the main heatsink is installed. The ramsinks are applied with thermal adhesive, and can simply be pressed onto the RAM chips.

With mounting clips in place; imprint of GPU on TIM shows the base is more than adequate in size.

The appropriate mounting clips need to be screwed onto the heatsink, the mounting screws attached to the clips, and then the heatsink secured by attaching nuts to the screws. Appropriate springs and insulating washers are included to help protect the card from excess tension and short circuits.

The heatsink in place.

Only two of the four mounting holes around the GPU die are used, but the heatsink seems secure enough without the extra screws. When mounted, the heatsink could be rotated slightly, but the GPU made good contact with the heatsink, and there appeared to be enough tension to hold the heatsink securely in place.

Cross-headed nuts are hand tightened on the back side of the card.

Once the heatsink is installed, the card can be installed in the system. Only then does the fan bracket, which attaches to the expansion slots on top of whatever cards are mounted there, need to be installed. Done correctly, this should position the fan directly in front of the heatsink, blowing in. The fan itself sits above the expansion cards, leaving room for whatever other cards are mounted below the graphics card. It's not clear whether there would be room for the fan if the card was mounted in a lower expansion slot. Very small (MicroATX) or very narrow cases could pose a problem.

This shows the relative position of the heatsink and fan.

The fan sits above the expansion cards.
