Does the Windforce r9 290 have the same pcb as the reference model of the card?

I'm trying to find out if my Windforce 290 is compatible with the NZXT g10 water cooling bracket.

No windforce is a custom PCB

Yes windforce has a custom PCB, to the best of my knowledge from research the die, die height and screw spacings on the gigabyte windforce r9 290 PCB have not been modified from the reference PCB.

Meaning that the NZXT Kraken G10 water cooling bracket is in fact compatible.

Same PCB layout so the Kraken G10 will work. A simple google of the Windforce and the reference gpu would show you this.
