Welcome to the forum
Glad it helped, rage
No revs the problem was the sound card (which has no ventilation at all), was applying A LOT OF HEAT right on top of Video Card number 1.
So that card (while playing), could reach up to 80C, and that was just starting to worry me.
What is the max recommended temperature for these babies?
