820-3115 quarter fan spin

[Kyle93]

820-3115 has no liquid damage. Fan spins for 5-10 seconds, stops then continues this cycles. All power rails present including vcore. Already tried new bios. What to check next?

During the 5-10 second quarter fan spin the pch gets burning hot. Could this be the issue?
