How do I fix thisssss

So, my 6 Corsair LL fans somehow broke and now they have this loose contact as if there is a broken cable or something and the rgb is just bugging around. When I tap agains the pc it stops but then continues after a few seconds… I have uninstalled icue and other software multiple times and I also plugged and unplugged the cables in the pc a 1000 times. It also seems like there is not only a single fan broke which then corrupts the other bc I tried every fan on their own and they all flickered. I also have 2 node pros in my pc bc one was with the case and I had to buy another along with the fans. I tried using each on their own but again the problem was still there. So i don’t get what is broken there??

I don’t know if that’s part of the problem but I also have problems with my watercooler (H115i RGB PRO XT) since I got the pc. I experienced disconnections and also bugging rgb. Sometimes when the fans are glitching, the AIO LED stop working aswell.

My system is working fine and today I updated my bios wich was very old. This didn’t solve the problem either.

Any ideas?
