Also a good contact with the cpu to the heatsink helps.

Before my upgrade my AMD64 3000 at it's stock clock speed of 1.8ghz, on its socket 939 motherboard, would sit at about 50c without load and touch 60c when under load.

This I took as normal, during the upgrade we removed the heatsink which was thermally connected via a heatpad, we cleaned this off and used Artic Silver paste, this now has made my cpu sit about 40c without load and barely touch 55c when under heavy load.

Of which I am very happy about.
