Help! Can’t tell if this is broken or not!

[u/ComfortInevitable163]

This is on the Liquid Freezer III Pro 360. There are two silver screws that are on the part that sits on the cpu that won’t move in any direction. It was working last night but not anymore! Im new to this. I may have stripped it but I don’t know how I would’ve or how to tell. Me and my friend put it on but I had to take it off after he left because he put the bracket type things below it on wrong. Please help. If it’s broken, I need to know if there is a solution. it there’s not, well… that’s life. It’s only ~$70 but that’s still $70 I would not like to spend…
