Hi Alex,
Glad to get your email.
We found the PCB photo of ZOTAC Geforce 1080 AMP EXTREME CORE EDITION in the following link. Is it correct?
If it is, our water block BP-WBV1080ZAMP-H-BRGB is not compatible.
You can download the installation guide of BP-WBV1080ZAMP-H-BRGB,
and compare the PCB photos of each card, they are different.
If you have any questions, feel free to contact us.
