I found this link check it out.

Mod City "Link Fixed"

Use at your own risk. If you melt your CPU don't blame me.

I have done this with an aluminum heatsink before, back when I had a AMD thunderbird 850. The important part is to use a really smooth surface to adhere the sandpaper to. Glass definitely works best. This is definitely not dangerous to the CPU. When you start lapping cores, or popping heat spreaders is when the trouble can really start.

I have a P160 too, awesome case.

I've done this for quite some time.  It's been a well known fact for quite some time that not all HSF units are machined equally in terms of flatness, and a smother surface means less microscopic gaps for air.  With less gaps and better mating surfaces, you get better temps.

I lapped a TT Volcano 12 and it lowered my load temps by a degree or two. I didn't go as far as using Brasso, from what I've read of other people's laps it doesn't make a noticeable difference in temperature, and how are you gonna see it nice and shiny once it's installed?

lappings been about for ages but it takes serious time to do properly and if you dont keep it properly flat ALL the time youll end up rounding the edges and making the whole operation pointless.

and if you do succeed then make sure you dont go and gloop a ton of thermal adhesive on it, a properly lapped surface will need less than normal.

I also have one. And I like it too. (well, it could do with more HDD bays...)

I'm not using internal cd roms. So I have up to 8 Bays I could use for Drives.

One thing i've was wondering: if it's constantly heating and cooling every time you turn your comp on and off, wouldn't the heatsink warp a bit each time? I mean even if it's totally flat when it's cool doesn't mean it will be flat when you get up to operating temp.

Obviously the thermal compound will help, but it makes you wonder if it's worth the effort...but one or two degrees cooler is one or two degrees cooled I suppose.

Well, always keep in mind that Arctic Silver (like the one used in this example) is not based on silicon and therefore achieves its thermal conductivity through having small particles. A polished surface (or even two, if you want to take the risk of polishing your cpu) is not the ideal environment for the use of Arctic Silver thermal compound. That's why I rather like the structure on my heatsink.
