Actually, the fan doesn´t make a big deal of noise, but regarding the power supply I seldom use my laptop´s battery (mostly connected to DC), but not sure if it will provide enough power for the processor to run... the cooling systems consist on a couple of copper looking little pipes that go from the bottom midle section of the laptop (dissipators... maybe?) (where the processor is) and are connected to the fan and another heat dissipator that takes the heat out... the laptop has never got seriously hot, I mean, nothing noticeable at least, I think the cooling system is pretty good and should be able to handle the heat coming from those 10W diff... 
Additionally, I´ve check the AMD site for my MoBo and it states that it should be able to handle ANY of the Phenom, Turion or Athlon... :S
