Good afternoon, Soo.. I build first time pc, after some time I realize that fans spinning too fast without doing nothing. Solution was connect fans to MOBO, then MOBO can control the speed of fans. So I did it. Connected 4 case fans in to one mobo chip (sys fan5 pump), tried tun on the pc, and then it shut down after 2-3 sec. I was able to smell burning. I took every part out to find out where exactly it was burnt and i found it was burnt at the same spot where i pluged in the cable with fans. In front i looked that its nothing happened but at the back i was able to see some black burnt spots. So. Can you guys tell why this happened? And.. Could other parts be damaged aswell? CPU, RAM etc. I hope you will understand what I wanted to say. Thank you. MOBO: Gigabyte aorus x470.
