Picked up two 6850's for a crossfire system on my dad's machine. His motherboard (asus) has the pci-e slots so close together the cards are basically touching. This means they are overheating (or at the very least, near their limit) based on GPU-Z while running 3dmark11 to test it. I am thinking that removing the plastic on the topmost card would allow air to flow in and cool things better. GPU-Z indicates sensors show temps hit 80*C during 3dmark11. Is it possible to remove the plastic shroud on the uppermost card so the card will get better airflow? Has anyone ever removed the plastic shrouds? How do I do so without breaking anything? Thanks!
