So, is it worth defacing the CPU for a few C? Especailly if that CPU is known to run fairly cool?

That CPU won't be worth jack in 3 years. (assuming it is a retail CPU) I will be surprised if you still have it.

Lapping it will take between 2-4 hrs. Depending what grits you use. The whole idea about lapping is to get it as flat as possible to get better contact between the hs and chip.

Just use a very flat surface like glass. Sand till you see the copper and the surface looks flat. then go higher on the grits.

i thought mine was only a year...

i had computers for 4-5 years before...just lapped my P4 after i had it for 3 years...

i guess i can hold off on lapping.

It's not a question of layers, it's a question of flatness.... The point of lapping is to create 2 very flat surfaces after all...

With a CPU, what you want to do is lap with 200grit until the copper is exposed uniformly on the chip... at this point, you want to take a sharpie and swiggle lines all across the IHS... give it a second to dry then give it about 2-3 strokes on the paper - if the IHS is flat, the entire surface would have made full contact with the sandpaper and taken the sharpie marks off on every portion of the chip... you can then move on to your higher grit papers, doing the sharpie test on occasion to ensure that you are still keeping the chip flat

The amount of IHS taken off is greater with the lower grits.. a flatness test is critical with the lower grits to ensure that you only take off what is necessary for a flat surface and don't overlap...

As for the question of warranties, I've found that if your CPU is working properly when you receive it, there is very little you can do that will require an RMA (aside from unsafe overvolting or physical damage (which would void the warranty anyways))

I would have to disagree on this point... If the seller of the CPU has already lapped it, that means that any fears that an unexperienced buyer had of destroying the CPU by lapping it himself disappears... and even if the buyer WERE experienced at lapping, it just means less time monotonously moving something over sandpaper, and more time tweaking/gaming... Also warranties on CPUs are non-transferable

If anything, lapping ADDS value to a CPU

If its an OEM chip then it should be a 1 year warranty... retail gets a 3 year.

thanks guess mines 3 years...

btw my P4 is still worth about $50 @.@
seem people sell 3.2ghz P4 for over $200. ***
