Moving back to the design of the heatsink itself, in these pictures you can see a close-up of the finish on the base. The finish on the base of the heatsink is, to the eye, not very smooth at all. No real reflections were visible, and although polishing and lapping of the heatsink might yield temperature bonuses, I believe that if it were truly necessary, it would already have been done. The construction of the heatsink is rock solid with no sharp edges found. While not very light, the heatsink is mostly constructed of aluminum and should present no real danger to anybody's video card, residing as it does right next to the motherboard socket. The KuFormula VF1 Plus is compatible with almost every video card you can buy on the market right now. All that is required is to mount it to the various different models is to change the flat "link" pieces from one shape to another. The links are attached to the heatsink via two screws, and themselves are attached to a threaded bolt via a plastic C-clip. This type of configuration. allows for flexible interchangeability if you decide to switch from an NVIDIA card to ATI and vise versa.
