EliteDesk 800 G2 DM... 901 Chassis Fan Not Detected

HP Recommended
EliteDesk 800 G2 DM
Microsoft Windows 10 (64-bit)

I recently purchased an EliteDesk 800 G2 DM as a bare system (i.e. without CPU, HD, RAM)


After adding CPU, HD and RAM,  on boot-up, this post error would occur:


Fan Detection Error, 901-Chassis Fan Not Detected.(rear)


I can hit enter, and the system would proceed and appears to run just fine.



1) The unit purchased did not come with a "HDD fan", but the HP maintenance guide seems to indicate there is a HDD fan (HP 839245-001) in addition to the system/CPU fan.   Is this error indicative of missing the "HDD fan"?

2) I've searched extensively and could not find availability anywhere for this part number (HP 839245-001), is there an equivalent part?

3) if a HDD fan is no longer available,  how could I configure the BIOS to ignore this 901 error (without having to acknowledge it each time).


Many thanks in advance.,
