For CPUs, you lap the IHS (integrated heat spreader), which is metal top of a CPU that covers the actual core(s). The goal is to lap that until the nickel coating is gone and the copper is exposed.

Eventually if you lap both correctly, they will have an almost mirror shine, or can actually have a mirror shine if you work at it enough.

umm,as its said,it should void the warranty.Still,thanks to anyone who helped,+rep

yea they pretty much do the same thing. its all to better the heat transfer, for the casual gamer though it wont make a difference since they are not always playing with the oc settings.

You use sandpaper to take extremely thin layers of metal off your heatsink, and because your applying even pressure this makes the base of the heatsink flat. Once it's flat, you then move up through the grades (so you'll be using finer and finer paper) which means there are fewer tiny holes in the heatsink surface and so more surface area to transfer heat across

GoneTomorrow - have you tried tapping the sandpaper to a flat surface, such as a piece of glass, and moving it backward and forward? If that's what you've been doing, what about the opposite - clamp the BT in a vice and do it?
That's exactly how I've been doing it - taped to a flat surface (side panel of and old case). Actually I've been making decent progress. I've spent about 4 hours total in two days.

Never tried it the other way though - how do you do it then? With a sanding block?

I've always wanted to try one of those electric belt sanders, but they're so powerful I think I would just ruin it.

And yeah, although I've been tempted many times to lap the CPU, I don't want to void the warranty.

Has to be asked though, how likely is your CPU to fail once it's been lapped? As long as you don't kill it while lapping, it'll most likely outlive the warranty even when heavily overclocked.

yeah,but i rather buying watercooling stuff except lapping and killing my warranty.

I think of it as an adventure when I lap my HSFs. It's always nice to see the before and after. The difference is tremendous. I usually do 400, 600, 800, and 1000 grit. Just pop in your favorite movie and lap away and once you get into a rhythm, you don't even know you're doing it anymore. You don't have to apply too much downward pressure. Let the weight of the heatsink do that for you.
