open Firefox  I go up to 3.6g of ram . All the fans pick up to pull the heat off
like they should

That is double bizarre... First that you think you're using that much memory, and second that you perceive the fans picking up because of it. Memory always has data, even if it's random bits, and memory refresh takes the same power keeping your data and junk intact.

Either you're utterly wrong, or something in the system is using the CPU in a big way, which will definitely draw a boat load of power.

In short, with a terminal and system monitor running, I see no excessive memory or CPU usage. If you are seeing a real symptom, something other than fc21 is involved.
