So i just bought some small Zalman VGA ram heatsinks and it told me to put it on top and bottom of the graphics card ram heatsink. Just to make sure before i put it on the top and bottom of the graphics card i wanted to make sure if its electricity conductive or not. My graphics card is nvidia geforce gtx 560ti direct cu ii top. Also how much heat can a gpu ram take? When im playing games like bf3 i get temps up to 146 F and when i touch on top of the ram on the gpu and it was burning hot.
