Server constantly rebooting, but will stay on after unplugging for a couple hours (Gigabyte GA-7PESH4)

Whenever I need to reboot the system I end up having to power it down for a couple hours before it’ll boot without restarting every 6 minutes.

Originally I thought this could be a cooling issue, but I’ve got this installed in a Phanteks Enthoo Pro case with 1 x 200 mm fan in front, 1 x 140 mm fan in the rear, 3 x 120 mm fans in the top, 1 x 40 mm fan installed on the south bridge and 1 x 40 mm fan installed on the north bridge.

Would anyone have any idea why this occurring and if it’s due to a cooling issue what more could I do to mitigate it?
