Zalman's ZM-VHS1 is a small heatsink designed specifically for the HSI chipset on nVidia's GeForce 6600/6600GT AGP graphics cards only. Some AGP 6600/6600GT graphics cards are supplied with a heatsink that also cools the HSI chipset, meaning that the VF700 would not be compatible. The ZM-VHS1 solves this problem. It attaches to the HSI chipset independently of the main heatsink meaning you can install the VF700 along with the ZM-VHS1 heatsink.
