I think I know the way a heatsink basically works... you glue it to your processor and because it is a metal with higher conductivity and greater surface area it absorbs the heat from the processor and then sheds the heat into the surrounding air.
Right?
My questions is this... Since video cards have the flat little processing blocks on them, would it be possible (or if yes, would it be advisable) to glue a heatsink onto a video card?
