Due to reference power socket, most of GF GTX 680 is NOT compatible with AX3, though this cooler has been made for it.




Looking at pictures of Newegg, I found two cards that use the reference PCB but with a down power socket. Most likely, they are compatible with the AX3.

They are the following:

MSI N680GTX Twin Frozr 4GD5/OC

GIGABYTE GV-N680OC-2GD

I hope this topic helps someone and that more tips are posted.
