I tested the operating temps and found the new gap pad seems to decrease the CPU temp a few degrees, although I wont claim my methodology would stand up to a peer review process. : ) If I was real gung ho I would find a thin but rigid copper plate to sandwich in between the frame and CPU, making sure to insulate and spots that might come in contact with the motherboard. THe 2300 has a thin "bat-wing" plate, but it is very thin. Mad Dog
