Generally RMA are refurbished, but if it's just for the thermal pads they might mod it for you and send the same card back? (just pure speculation on my part) New products aren't generally given for RMAs, but there are exceptions (I think if it fails within 30 days of purchase, or if they don't have any Refurbish products on hand for example that I know of)
Will have to wait for an EVGA rep to answer, to be sure there isn't an exception made however.
