Water Block use for AMD Sapphire Nitro+ Radeon RX Vega 64 8GB HBM2 (11275-03-40G) Full Cover GPU Copper Block with 12V 4PIN RGB

This waterblock is manufactured by Bykski. I was a tad nervous as I had never seen too many reviews on this particular model, but after hours and days of searching, this seemed to be the only waterblock that was created for the Sapphire Vega 64 HBM2.Instructions are in Chinese, but easy to follow as each step has pictures to accompany the writing. Some minor modifications and screw choices had to be made to keep the original Vega 64 backplate on the card. Highly suggest using Arctic Silver 2019 edition for your Thermal Paste of choice.This was my first custom loop and my GPU is currently sitting at 22-24C idle and couldn't break 29C after 5 hours in AIDA64.

This thing fit perfect on my Sapphire Nitro + RX vega 64, i kinda wish they had a English version of the instructions and the RGB controller, i cant read it! And not all the screws where there for the back plate, i had to install the back plate with 3 screws missing i guess i am not the only one in the reviews with same missing problem. Over all it does its job i highly recommend Bykski water block, the company haves good products.

This is a great water block and exceeded my expectations. Bykski may be my go to brand my my boy blocks. Build quality matches my EKWB water blocks.The installation instructions aren't in English but the install process is the same as any other waterblock.

Can't find a better water block for a Vega 64, setup was straight forward (but not for the faint of heart, which is true for any GPU water conversion).
