JMke over at Madshrimps has the goods on an upcoming TEC cooler for video cards from MACS. Though it's a dual-slot solution, because it's a TEC, you know it'll be a kick-ass cooler. Images at their site.

"They are concentrating on making the TEC cooler work for VGA cards, the TEC is rated up to 18W and is cooled by a massive construction of 4 copper heat pipes, a large copper base and a series of aluminum fins which are cooled by two 80mm fans."
