Nice job, I just hope you didn't use any type of polish or you're defeating the purpose of what you're trying to accomplish

great job, make sure you lap your cooler so you can take advantage of your nice even surface.

Could you explain what difference it makes please?

Using polish fills the micro abrasions with it and leaves a layer of film on the CPU. Both reduce heat transfer.

Dayam!  that looks good.

DEAR GOD!!  that is incredible! 


Mine (2000 grit):


you win.

Hey nateman. I guess you can say "He LAPPED you!" huh?

True. GREAT work on the lapping btw Hork!

Then he must have had a whole lot of time cause he went all the way to 8000 grit.
 
I guess you just ain't got a whole lot of GRIT huh?

****, I didn't even know 8000grit existed!

I would've bought that instead. I did this with 2000grit:

I've called about 8 different local hobby shops this morning and have yet to find one that carries >2000 grit sandpaper. 

Great job Mr. Hork!

Here's my E8400 and CNPS9500

hey hork that is an awsome job you did there

Hey all, this is not meant to hurt feelings or belittle anyone's hard work, but "shiny" is not the only goal to lapping. Flatness is the real key to proper heat transfer and I can say with my experience using the lapping guides inside these forums, it is not easily obtainable. My last attempt to lap my i7 peaked my curiosity as to how flat was it? It's shiny and reflective but.....So I took it to work and used and optical flat to measure it and it was not even close! It's extremely difficult to maintain equal pressure during the lapping process which translates into a surface with concave/convex characteristics.....What I did to resolve this was to use a lapping plate at work which is essentially a "certified" flat surface made of granite/quartz.....After many hours of hard work and numb fingers I was able to produce a visible "flat pattern" of apprx. 80% coverage of the cpu face and my TRUE....it was not as shiny as the photos in this thread, but it was truly flat and that is more important for heat transfer. Again my intention is not to disrespect but to share knowledge.....

agreed.  so what was your technique for using equal pressure.  Glass is usually the DIY choice for lapping, so would would you suggest?  do you have a pic of your chip?

ummm....


Does his head look flat to you?  


I have gotten the same mirror polish on 2000 grit, but  i needed polishing compound to do it.  I am not sure how much better it performs, but for a north bridge chip, it didn't make a difference for me.
