Looking for troubleshooting advise for this issue being alerted as Critical in OME.

I am receiving solely the Power Supply redundancy is lost alert without any sort of issues with either of the redundant power supplies. There isn't anything correlating in the hardware or event logs concerning power or the PSUs. However, I am seeing a "The memory module 1 temperature is greater than the upper warning threshold." at the same time frame (only thing consistently mapping up over past week. The redundancy is lost for 8-10 hours and then comes back for 16 or so hours over past few weeks.

All firmware and drivers are updated to current Dell pack. that seemed to address it for a day or two...

Before I send a field person to look at it, any ideas what this might be???
