tested the Quad (system 10.4.11, 8GB ram, HDD 2 x 1TB) with a full 3D rendering ( LightWorks ) of a building

Activity Monitor

all 4 processors fully used, for a while during rendering



istatpro



if the rpm and temperature of A and B are more or less equal, > good

rpm of the A en B pump ± equal, (equal up, equal down) no worry about leaks

30 minutes later, but it's the same as 3 à 4 minutes later



i always choose to set the energy system to highest,

because the fans are spinning at low rate from the beginning

and there are less peaks,

temperatures are fairly stable
