You should have mentioned you were a folder earlier, I would have helped you.
The Twin Turbo Pro is an excellent cooler that is way way better than the stock cooler on the zotac AMP. People saying that it's not as good as the stock cooler are out of their minds. The actual GPU core will be atleast 10+C cooler than the stock cooler. It's true that you need to consider VRM cooling but the stories about VRM explosions you've been hearing would've happened with any other cooler as well because if they were pushing enough volts to overheat the VRMs with heatsinks then imagine what they would've done with the reference 460 cooler which has no VRM cooling. That's right the reference 460 cooler has only incidental airflow to cool the VRMs and it does just fine, so any
VRM heatsinks will be an improvement over that, and plenty of people run 1.1v on that card without any problems even folding 24/7. So whatever you do don't put the crappy zotac cooler back on, just keep the TT pro and if possible make sure you have some heatsinks on the VRMs, if you can't then they will likely be fine without them but if you're really worried you can just stick to 1.063v instead of 1.1v. The one redeeming quality of the stock zotac cooler is that it's supposed to come with some VRM heatsinks, see here
, so you can either use those if they are still on there, or if whoever put the AC TTP on there used the ones that came with that then those would be fine too. If you don't have any VRM heatsinks then you can either just stick to around 1.063v or if you want to go for 1.1v and still feel extra safe then you can pick up some of these little hunks of copper
and throw them on there.
