EK has prepared a full cover water-block for the upcoming AMD Radeon Pro Duo. A photo on the product was just posted at the EK facebook page.
Technical specification of the block are not yet shared, the photo shows a Nickle plated copper based cooling block that covers the entire PCB. That will cool down the two FIJI GPUs worth HBM stack completely.
The card is single slot this way and can ueasily be added to an existing liquid cooling loop. EK is showing the product based on see-through acrylic, but likely they'll offer more models. AMD Radeon Pro Duo will be available in the stores starting this week.
"AMD Radeon Duo Pro a.k.a. Capsaicin water blocks from EK Water Blocks are ready to rock. There has never been so much GPU raw power stuffed on a single PCB!"
