Translated from German (at best):
While the GeForce 9800GX2 specs and launch date still haven't been officially
announced by Nvidia, we have discovered the first release of a water cooler for the card, by Innovatek.
The Innovatek radiator will fit the 9800GX2 and it will also fit an unmentioned
water cooling unit named "9800X2" (?). It will run cooler, and all major components of the card on both chips will be chilled, including all memory modules and voltage transformers, as well as the bridge chip that connects both chips. The water block and the card will both be presented after CeBit.
Any German speaking translators care to clarify? Original link:http://www.pcgameshardware.de/aid,634285/News/Innovatek_Erster_Wasserkuehler_fuer_9800_GX2/
