Picked up one of these Vantec Spectrum UV Fan Cards for the sake of utilizing one of the 3 empty pci slots I had....
However, the dang thing fit my mobo very... strangely. The fan card can only fit in one way with its plastic pci grooves, but the fan speed controls and logos are all inverted. I put it in a couple slots below my video card (my card doesn't even really need to be cooled, I just felt like putting something in my computer for the time being) and now all it is accomplishing is sucking air in from below the card and shooting it at the bottom of my case. At least it is moving a lot of air around the case on the bottom, but now I have to move my video card to the lower PCI-E slot and move the fan card to a PCI slot above it so that it can shoot the air down onto.
Just thought I'd share this little experience with you.
On the plus side, it looks really cool, blows a lot of air, and is fairly quiet to me. Good way to fill a lonely PCI slot for under $20.
