Has anyone here had any luck correcting the HardWare (HW) issues with their D3's?  I have 2 that are running with over 50,000 HW in a 24 hour period. I have tried letting them cool down, a complete factory reset/reboot, updating firmware, etc... The temps are good, with the highest being 74*C right now.  Output is good, power is good,

Two of my other D3's run with less than 100 HW in the same period. 

Any suggestions are greatly appreciated.
