KBtrade, you are right, the retail box comes with the heatsinks unattached in a separate compartment. What cdrakejr might be saying is that if you put the retail heatsink on and run for a few days, then it might become difficult to remove it when the cpu is cold because the thermal tape attaches very firmly. What you could do in this case is to run the computer at slightly higher voltage to warm it up, shut it down and remove the heatsink before it has a chance to cool down..
