Why are AGP/PCI cards upside down with the heat generating IC's facing down.
The PCB and chips are laid out mostly on one side...
The mounting slot and bracket have them face downward.
Doesn't heat rise?
Take a desktop PC, with a flat motherboard.
Now flip it upside down.
Doesn't that have a negative effect on the temps due to the cpu blowing heat down?
Or being in a closed space, it's all about the same?
I know BTX has an air flow design...
yet the upcoming PCI-E cards are still down facing...
Does anyone know the reason ISA to PCI flipped the card orientation??
