S.M.A.R.T. and OWC Aura Pro X SSD (Tech Tool Pro 9.6.1)

Just got an "Over Temperature Threshold" warning from TT about this device. I've been using 9.6.1 since it was released and this SSD has been in my Mac Pro (High Sierra) since December. No problems have been reported until just now. I just finished a chat with OWC and was told that the Auro Pro X doesn't support the thermal reporting part of S.M.A.R.T. If that's the case, then perhaps Tech Tool's reporting is in error. What can you tell me about this?

Thanks,
Michael
