I have Seasonic 550w supply, MSI x370krait mobo, NZXT S340 Case
I have connected my 3 pin case fan to system fan and it worked just fine.
Is this problem with my cpu cooler?
 


What did you connect your CPU cooler fan too? It should be connected CPU_FAN1, it's inbetween the RAM and the CPU socket near.
