i cleaned the inside while looking for leaking fluid.. there is no dust anymore stopping the air i think.. i always set the energy system to automatic.. the system seem to run fine.. no kernel panic it just get loud sometime mostly while watching flash stuff , the old g5 dp didnt do that .. when i load all the 4 cores to 100% it will peak around 77 celcius on cpu1 core b and cool down to 65.. and the rest of the cores will be around 60-61.. fans will go up to 2700 rpm under full load.. is it normal ?
