Heatpipes, Al & Cu, oh my!The power of PC video cards has grown beyond the processors that host them. Today's graphics processors have more transistors than even the most powerful
dual-core CPU, which translates into alot of heat production. Even when the GPU is idle, it can generate massive amouts of thermal waste that must be disposed of via heatsink.
Since today's graphics processors are the hottest ever, we are seeing heavier and more robust stock coolers to accompany them. While these stock coolers are much better than the previous generations, they are still only barely adequate to deal with the new level of thermal production. The current GPU king: nVidia's 8800 line of chips, generate some serious heat and need an equally serious cooling method.
Zalman has released two sister products to augment each other when cooling your 8800 video card. Zalman's VF-1000 LED is a pure copper cooler that can be used on nearly any video card made within the past 5 years. The components on nVidia's 8800 need some additional cooling, so this cooler is meant to work with the ZM-RHS88 ramsink kit. When combined together (a la Voltron), these two products augment each other to cool even the powerful 8800 GTX video card.

The memory doesn't really get that hot, even when overclocking. The fan blows over the ramsinks, too so they stay nice and frosty.
