OK.
So, since you are using a lot of multimedia, it seems to me
that the Intel HD3000 is also incorporated into the CPU.
Thus the very high CPU usage while doing graphical UI's
and multimedia.

Only thing I can suggest is to disable the Intel graphics
and re-enable NVidia. This will reduce the cpu overhead
and heat generation;  and just be sure the Nvidia card's
fan is at full speed.

I would also be sure that you have a full complement of
cabinet fans.
