The Gforce 256 takes a great deal of power through the AGP port and the GPU gets remarkably hot even when not overclocked and if you have a fan that draws its power from the graphic card this only adds to the problem. I use a blue orb to cool my Gforce with its power supply drawing from the mobo and not the graphics card, I dont see the point of using ram sinks as my RAM never gets hot
