Summary: Zalman website claims this VF-900 fits on the Nvidia 6800 series but does not fit on my MSI 6800 GT! It is so big that it actually drops down to the bottom of where the card slides into the AGP slot. Since there is a pci slot (empty) next to it, this deep heatsink hits and sits on that empty pci slot, thus not allowing the video card to seat in its own AGP slot!! This is on a Dell Dimension 4600.
NOT for X850 Crossfire. Will not fit unless you modify.

Summary: This thing just killed my crossfire mastercard. The mounting screw is way too thick that it won't let the two cards sit down on my crossfire set up on asus mvp motherboard. The mounting screw has a pvc washer that also sits directly on top of 2 resistors on X850 mastercard. I didn't realize it had ripped off my resistors until it's too late.
