Hmm, could this be bad for the card?
it's already running pretty fast it seems. I wont rely solely on this as a fix, but will do it in addtion to perhaps.
There are also 2 PCI slots in between the cards, so I'm going to pop the covers off those to help with the air flow.
I would put a fan on the back to help draw air out, but it would have to be a rectangle & go vertical between the two cards on the back of the box.
