I've been having a heck of time diagnosing the source of the MOBO alarm of my SuperMicro X7DCL-3. I'm using passive heatsinks, and the CPUs are Xeon LV-5148.
Initially I thought it was a CPU overheating alarm. But after booting on a cool spring morning (ambient room temp 16C), the alarm still sounded even though the BIOS reported the CPU temps at 20C. It even reported the CPU temp as High while at 20C. My understanding from reading the manual for the SuperMicro X7DCL-3 is that it uses the CPU's manufactuer set TDP to inform the BIOS if the CPUs are too hot.
I was able to find the jumper connection for the internal speaker and remove it, so at least there's no more alarm. But ignoring this alarm unsettles me, especially when I need to deploy this server ASAP, as it is my backup server for my main server.
