Hi there.
I've recently built a new computer.
I have a 3950x CPU, in an MSI x570 Unify motherboard.
I am using a Noctua NH-U12A cooler. A corsair 1200W power supply. 
The temperatures are really high and act really weird.
They consistently and periodically jump -+10 degrees, making a consistent zigzag pattern on the graph all the time.  Even while the computer is mostly idle. Going as low as 54 degrees and as high as 75... My case fans have no idea what to do lol...
Take a look at this graph. Pretty sure this is not normal. 

Any idea what's causing this and how to fix it?
