Temperature problems after fan change

[Zenfin]

So today I was changing fans in my pc. Old ones out new ones in. That easy... I thought. After starting my pc it had temperature problems and shut itself down. The AIO (NZXT Kraken x62) was making weird noices it hasn't done before. The sound is coming from the pump.

After that happened I checked every cable nothing was wrong with them. So I wanted to check again... Maybe I can find some info that's showing me something more specific.

Now I also have the problem that my monitors aren't getting a signal. So I can do nothing right now with it.

Now I have changed everything back to what it was befor I made today's changes. Still not working. I also ordered a mobo buzzer to see if I can get any info from that. For this info I have to wait till Monday. 

 

If you have a clue where the problem is, I would love to get help with it.

I used the standard fans and wanted to change them to the corsair ll120 and 140 fans

Sounds like a power supply issue, unplug and replug everything.

Did that already. Didn't do anything.
