Im running the Sapphire 7970 OC Dual-X edition card (http://www.newegg.com/Product/Product.aspx?Item=N82E16814102982) and bought the koolance VID-AR-797 waterblock (http://koolance.com/vid-ar797-video-card-vga-amd-radeon-hd-7970-water-block).
The problem i am having is that after I installed the block, the block doesnt seem to be making full contact with the gpu die. Total surface are of the block touching the gpu die is about a grain of rice, or less. Also, the memory pad impressions are very light. The card is reference PCB (getting it confirmed by sapphire atm) so im not sure whats up. Ive seen videos of the card working with other water blocks
Spent time emailing coolance and they confirmed that its not normal for this to happen and suggested that it may be the standoffs; but they look fine. Before I RMA the block for a new one or just sell it (cost too much to return it; cheap ass koolance) I wanna know the following:
1. Has anyone had similar problems with refurb blocks like mine
2. Did AMD/Sapphire lower the gpu die
