What's the chance these would be compatible with a GTX 670 FTW?
Slim to none unless Corsair thinks there is a profit to be made with an outdated GPU. They have to custom make the plate to fit the 670 FTW. Also your card must be the 670 FTW that have a single stock blower fan, not a model with dual fans.
