he vram is directly under the fan

I got power to the fans using a SATA to 4 Fan 12V adapter.

I tried putting a heat sink under the other fan but the temps went up. There's little holes in the backplate of the card on either end of the card and I think the air flow going into the holes helps circulate the air for lower temps.
