That's a good theory, but if you saw the youtube video i posted earlier, the PSUs are not really positioned to do much cooling, they are stacked up vertically on the left side and all 4 of them occupy maybe only 20% or less of the total cross-section of the air flow. I would think that a response to overheating would primarily force the 6 main fans to spin up... they are spinning rather slowly though, even for big fans.... 1500RPM? Must be quiet though...

Or perhaps the high fan speed in one PSU is part of a scaled response to the high CPU temp. Maybe at higher CPU temps the other PSU fans will spin up to high speed. _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq _______________________________________________ Linux-PowerEdge mailing list [email protected] https://lists.us.dell.com/mailman/listinfo/linux-poweredge Please read the FAQ at http://lists.us.dell.com/faq
