Temp sensor location -Synergy 12000 frame vs compute modules
Due to a recent cooling event, I'm taking a much closer look at my temperature readings with an eye to adjusting the alert thresholds. However, I am seeing a wide disparity of temp readings between my Synergy 12000 frames and the SY480 and SY660 compute nodes contained therein. In many cases they are showing nearly a 20 degree F difference. Where are the temperature sensors located in the 12000 frame from which the OneView Enclosures> Utilization >Temperature values are displayed vs. the temperature sensor location in the compute modules from which the Server Hardware > Utilization > Temperature values are obtained? For example, one of my frames shows a temp of 84 F but none of the compute modules installed in that frame show any temp value higher than 66 F? A similar temperature disparity shows across all of my frame fleet relative to the compute modules they contain - and I'm just trying to reconcile how the reported values could be so different between components that are physically adjacent..

Re: Temp sensor location -Synergy 12000 frame vs compute modules
The frame temperature represents a mostly incoming flow near the front panel (where the console connects). Any obstruction there could collect warm air (such as a door handle or racks with no flow front to back).
I believe the OneView server temperature is read from the iLO's: 01-Inlet Ambient = 20C
