Not a bad idea at all. Seems like a reasonable thing to do.

Did you apply the correct BIOS for this model?  There is no information I can find about turning off the fan because there is not a fan.

Thanks John.  i did not update the BIOS, just looked in there and did not see anything either, that is why I am at a loss as well.

OK, try to see if there is a newer BIOS. All major manufacturers updated BIOS the past January for the Meltdown threat. If so apply the new BIOS

This isn't a BIOS issue.  On the Z240 SFF board there is no front fan and the BIOS error message refers to the CPU fan, check the CPU cooler fan is spinning freely and consider replugging the cable.

Thank you for the ideas, but, the BIOS has no available updates and I re-seated the CPU and case fan connections and still get the message that the front chassis fan is not connected.  On the motherboard there is a slot for a front chassis fan, but of course this unit did not come with one.  I suppose i could buy one...

I am not sure what would cause this but trying another fan seems reasonable

The other thing you could try is reapplying the same BIOS

Can you grab a hardware monitoring tool like HWMonitor or SpeedFan and check that you've got real-time monitoring of the CPU fan speed?

you said " but, the BIOS has no available updates "  do you mean you have the latest already ?
do you still have warranty ?  then contact HP
otherwise you can try removing the bios battery, and bleed the electric charge

Thank you all for your help.  I am buying a front chassis fan to fix this issue.  It can't be a bad thing to add another fan anyway,
