I tried running it with the case open, not the same as having a fan blow towards the card of course. However, my friend has done so and it didn't make any difference.

I have a second card on a MSI Neo2 FR and the results are horrific when running a Linux Live CD: lost signal followed by only a half corrupted screen. That same card was doing more or less fine on the Gigabyte board, even though it had intermittent artefacts. I know the MSI board has PCI-X 1.0a.

Meanwhile I've decided to replace one of the cards with a 8600GTS so I'll be able to test my compatibility theory. The other will probably be returned for RMA as well but I think the replacement won't be a Gigabyte card.
