Jan 21, 2015 6:17 PM in response to Charlie Godboldby BDAqua,Hi Charlie, Powermacs were discontinued in 2005/2006, I think you have a Mac Pro.
Did the RAM come with Heat Spreaders?
Have you done a PRAM reset, CMD+Option+p+r...

Yes it is a MacPro, Cant keep up with all the nomenclature lol
RAM has heat spreaders!! Made sure of that.
I just shut down, let the unit sit then started using the command sequence you supposed. At the moment it is not over running the fans
I bought TGPro monitoring App first run with it showed none of the sensors were working correctly.
I will check the next diagnostic to see if made any traction. I really appreciate your help. I will give you the final verdict tomorrow.

Level 9 (60,909 points)
DesktopsDepending on the Vendor, it is possible you received RAM not intended for a Mac Pro, that does not have Apple-approved heat sensor chips on each module. If that is the case, you should return them for a refund.
The Mac Pro uses a carefully tuned airflow to reduce the temperature to acceptable levels while running the fans at acceptable "office" levels. Most other computers in this class just blast air over the DIMMs, and let the noise levels fall where they will.
Without Apple-approved heat sensors, the temperature information becomes inaccurate, and the software has no choice but to run the fans on their highest setting.

"Mac Pro" name has been around for over 8 years, starting in August 2006 once the G5 series retired (2003-Early 2006) had a short run.
A Mac Pro 2012 would still be a model "5,1" same as Mid-2010, just slight difference in processor offered. Still DDR3 1066/1333 ECC.
