AMDGamer has some pictures of Innovatek’s brand new Cool-Matic G70, and a link to Innovatek for more info.   The G70 is a water based cooler (block) for both the GPU and the memory on the just released 7800.  Before you ask, there are pictures of what look to be a 2 card SLI setup, so the G70 takes full advantage of the card’s smaller footprint to make sure both cards can be cooled with 2 seperate G70’s.
“Parallel to the upcoming Launch of the new Nvidia G70 Graphic Card -Monster (Geforce 7800) we have the suitable cooling solution ready and available today -> The new Cool-Matic G70 Special Coolers ! Power and silence come together an meet in perfection. Made in Germany !”
