Anybody know how to make vCenter quit complaining about a Noctuna 300RPM fan on a Supermicro motherboard?

Help

Note that I am already running IPMI tool to make it so the board doesn't fill up the event log anymore.

Since upgrading to the latest BIOS for my motherboard (X10SRH) and 6.7, vCenter has been screaming every 30 seconds about a FAN Failure.

Like I said above, I'm already using ipmitool, and the board itself doesn't complain anymore. Instead of a full event log like before, it's empty.

It has something to do with the VMWare CIM provider still thinking the threshold is 1000RPM.

At this point, if I can't adjust the threshold in VMWare, I'd rather just kill the whole alert. There's enough damned fans in that server that there's no risk of anything overheating.

Hopefully someone can provide some insight.

Its been a while since ive used Vmware/vCenter but i believe it is possble to disable specific alarms, not solving the problem but atleast it will shut up about it.

This is a fairly common problem with server boards and non-server fans which are designed to move decent air at lower speeds. First thing I do is go into the BIOS and change the fan speed. Supermicro usually has options for fan speeds, might be asking about altitude, just crank it all the way up, with Noctua fan you're not going to hear it at a more aggressive speed setting anyway. Next, on some boards (and it's been a while) you can configure, usually during the firmware flashing process, which fans are even connected. On some boards if you just lie and say no fan is connected then it won't report a problem. This may be Intel boards and I'm mixing up my memories, so please double check the documentation for this.

Now comes the extreme option that I've been meaning to attempt but haven't. I've seen people online that get small Arduinos or similar and wire them up to emulate the feedback from a fan so your board thinks it's running faster than it is. Bonus points if you read in the PWM signal from the fan and then multiply it by some factor so that you have some feedback, just exaggerated.

Why not run the fan straight from the PSU and skip the motherboard?
