Just my opinion, but if you are going to be so adamant and bold to state lapping destroys your cpu and does nothing, (I know the title you chose is a classic media 'hook' tactic, but you still need to be prepared to back it up :] ) why haven't you yourself tested to see if lapping does at all even work? All i see is opinion, baseless opinion with no refrences posted. I will agree that anyone saying they have dropped 20 degrees is absurd. hell even 10 is outrageous.
The process you posted is so incomplete and incorrect its almost laughable. Any experienced lapper (and lets not just tunnel vision towards cpu's, think of car and paint detail) knows you start rough to get the bulk of the imperfection's away, only to move to finer, finer, finest grits to get a mirror shine.
Now, from reading your article, i assume you are targeting the countless numbers of people who overclock and void their warrenties for minimal gains. And from what i gather, correct me if im wrong, you are really just trying to figure out why anyone, in your opinion, would be so crazy to do such a thing.
So I ask you, why do people climb to the tops of mountains? Jump out of planes? modify cars to go fast in a world limited by road signs?
I will admit that i do not overclock or lap my processors, unless i upgrade to a new one, and i just want to have fun and see how far i can push my old ones, so i am not at a loss. Some people have fun and enjoy pushing what they put their own money into to achieve new speeds. It's their money, they can spend it how they wish.
I have to comment on this part:
"Lapping is supposed to be complete when the silvery surface coating of the CPU is all gone and it reveals the coppery colored core material. Of course this assumes that the CPU manufacturers have invested countless billions of dollars into Research & Development just to coat their processors with a completely useless if not wholly counterproductive metal coating!"
The process and idea of lapping is to bring out the superior thermally conductive metal copper, so they will be in contact directly with eachother, instead of being separated by the lesser conductive nickel. This allows for faster heat transfer from the cpu, to the base of the cooler, up the heatpipes, and blown off the fins by use of fan. (or in some instances no fan is required at all)
I would never recommend lapping for the average home user, there is no reason to. The only time i would recommend it is in overclocking situations.
I think we can both agree on the temperature drops anything over 5 (which is already pushing it) to be a flat out lie. We can also agree the only people lapping and voiding warrenties, are the ones who are willing to spend the cash to get the performance boost they crave. I dont ask people why or try to reason why they choose video games over outdoor sports, i just know its what they enjoy to do, and its not my place to belittle them for their choices in what they find fun.
If this article was actually meant to hit the target audience of the "average home user" about the dangers of lapping for a mere 2 or 3 degree drop, then i completely 100% agree with all of it, except the process you posted
