* Some variations in AMD die height may require the use of a copper shim which is not included.
As for non-reference Graphic Cards, due to the large variety of these cards, we are unable to test and verify compatibility for all cards. This does not mean the G12 will not work with your GPU.
In order for a Non-Reference Card to be compatible, it must have the following
-The same mounting screw positions as the reference version of the card
-The Mosfets located on the right side of the card, so that the G12 Fan will provide sufficient cooling.
Below is a reference image that gives you a better idea of placement. Please use your best judgment when using the Kraken G12 with a non-reference card.
Please also keep in mind that the Kraken G12 does void the warranty of your GPU. Misuse or mishandling is not covered by NZXT.
