Shut down, fix your cooling problems, check all connections, power and SATA, both ends, including any power splitters.
I see you have Marvell controller, possibly on the motherboard, and Intel SATA controller as well. You might try not using the Marvell ports, or disabling IOMMU (vt-d in Intel) in the BIOS, I know some have had better success with Marvell if they don't have IOMMU enabled.
After exploring all that, boot up again and post new diagnostics.
