Hmm,

I have never had such a problem on my Onyx350 or RM Tezro so far.
So you say the massive blower next to the ODY sucking air from inside the chassis blowing it out on the back is ok and the fan between
the SCSI-backplane and the pci-x compartment is also running, then I assume you are right that the fan not working must be the one
underneath the V12 case. It would also make sense that the ODY is kind of disabled, probably in the PROM (console=d), without the
required cooling.
