you may not have to lap it,,the ziggy is a direct contact(heatpipes to CPU) cooler,,that's why it works so much better than the rest,,,,more cooler companies are starting to use this method,,,and i wouldn't be surprised to see this as industry standard in the not to distant future,,,,i would try it first,,,and if you are not satisfied with temps then go thru the trouble of lapping,,but i beleive you'll find it unnecesary,,,,
I hate to advocate drugs, alcohol, violence, or insanity to anyone, but they've always worked for me.
