Hi, at the time yes, and i understand what you are saying. its not noise i am worried about its the fact to how hot the system gets and watching the esx client and ilo i never see them change, here are the temps and fans at the time of this reply 
i do understand they are all normal now and never went to alert of warning but i still thing at close to 60C on system board the fans would kick up, also, the CPU runs much cooler becuase it infrom of everything, what gets hot is the ram behind it. i do know (to my understnading ) ddr2 ecc ram does run on the hot side.
thanks
