Hi Sven, I can't see any engraving on the external side of the waterblock. Should I unmount it from the graphic card to see it? I can read "Stand 12/2009" into the documentation delivered with the block. It has been shipped to me on February, 15th 2010. Its reference is n° 23483 in the Shop: http://shop.aquacomputer.de/product_info…roducts_id=2409 Thanks,

Hi everybody, I have the aquaduct 720XT and a GPU Block aquagratiX for HD 5970 (2x RV870) standard (not with Nickel plates). I've got an important difference of cooling between the 2 GPUs. Using games or stress tools like FurMark, I reach 60°C for GPU1 and 100°C for GPU2. Even in the idle state, I've got GPU1=44°C and GPU2=54°C. Water T°C is around 29°C. The graphic card is from MSI. I've used Noctua Thermal compound and checked that the compound is set similarly on the 2 GPUs and Memory chips (...
