I did it. It's SO easy! Just take a razor blade (I used the kind you put in general purpose razor tools) and rock it back and forth on the corner of the chip...then rock it towards the other corner until you cut half way through...and repeat on all 4 corners both ways. Make sure NOT to go deeper than about 2-3mm or you might hit one of those transistor pack thingers...
I did it to my 3500+ and it lowered my idle temps by like 6C or something....but if I remember correctly the load stayed basically the same.
