It requires a lot of time & effort to do it properly, but definitely worth it for those
extra few degrees of reduced temps if you're aiming for the highest possible oc's,
though remember it'll void the CPU warranty if you've bought a retail unit.
So far I've lapped a 540, TRUE cooler and a Q6600. Tip: take a picture of the info
printed on top of the CPU before starting the lapping process.
There are numerous guides on the net, including some good how-to movies on
YouTube. Here's one I read, though it's not the main guide I followed to begin
with (think I have that bookmark on a different system):
Here's the ebay source I used for the sandpaper:
I had a decent size piece of wood to use as a base, just needed a piece of glass.
Found a local glass maker, called them up & explained, they said no prob, come
on down (I walked instead of catching a bus, to minimise costs); they let me have
a sheet of 5mm glass 30cm x 40cm for just 2 UKP, which I thought was pretty
decent of them as I hadn't expected to end up with something exactly the right
size (they cut it from a larger offcut that was going to be thrown away). I figured
a piece that was maybe 1" larger on all sides than a sheet of sandpaper would
I used black gaffer tape to secure the glass sheet to the piece of wood. 2 more
pieces of gaffer act to hold each sheet of sandpaper in place. Here are a couple
of pics, the first showing the initial very course 200-grade sheet ready for use.
Second pic shows the 540 about a third of the way through the procedure...
But most of all though, if you're going to do it properly, then expect to spend
several hours on it.
