Installing an Accelero Xtreme IV on my EVGA SC2 1080ti. Help is appreciated.

Hi, so a little backstory. Not long ago I got an accelero iv for my card. Unfortunately though, Im not experienced with GPU cooler installation and Im very worried I might break my graphics card installing it. I found a few guides but none for my specific card as far as I could tell. Any suggestions? My thought process is : I could go to bestbuy and have someone from geeksquad help me, or do it myself and risk it. If you find any guides or resources or anything that would be of any help Id appreciate it very much.
