just use some needlenose and clip the push pin ends together and the heatsink comes right off. It will easily go back on by pushing the pins back through the holes. then clean alittle of the thermal compund off the GPU and read it (there is a ton of it and it is silver thermal compund.There will be enough still on just the heatsink so you don't have to reapply any to put the heatsink back on. They use a ton of it . Disassembling the card I think does not void your warranty. As long as you do not take that sticker off the card which says warranty void if removed you are all set!.
