For those of you that have lapped your core 2 duo IHS, could you post some pictures? before during and after maybe so i can get an idea of what to expect when i get mine.:D

By applying a solvent like Brasso to your processor's IHS -- more chemical molecules are put between your heatsink of choice and the IHS, so by polishing and adding chemicals to the surface you are realistically hurting your heat transfer.
Here is my 6600.

mmmm all these mirror finishes :D
Same here. Got a 10C decrease in idle temp and 5-6C got load temps on my e6700.Quote:

Love the shiney finishes, what makes me wonder though is why don't people like Intel actually ensure that the IHS is flat, after all they are the 1's concerned with heat output and effective cooling. Can't be that hard can it, just need to mill it flat somewhere in their production cycle.
My gawd!!! :eek2: How long did it take you to do that?Quote:

Lapping helped the E6600 a lot because it was shaped like a spoon, but the E4300 didn't get any decrease in temps whatsoever.
Omg dani and herm how did you get that finish? :eek2: :bows:
what kind of paper did you use? :clap:
Here is some pics of my work.
My E6400:

For the final cut I prefer to use wet'n'dry that is pretty much worn out or at least has had heavy use as it seems to give a more uniform finish. The keyy is to take your time doing it, I spent about an hour or more to get the finish in those screenies, but in all honesty as long as it is 'flat' thats enough.
very nice everybody.
very interesting I used a 2500 wet paper on my heatsink and it looks like I just rubbed it on a tar road :slapass:Quote:

p.s: Nice mirror finishes all! :clap:

polishing the lap job with brasso is not a good idea because it leaves a layer on the IHS.
well that is what I have read before numerous times, also it woudl seem that just leaving the IHS bare as your are going to use TIM would be a better idea?
On AMD chips the IHS's are usually pretty flat in my experience so lapping might not be that beneficial. There are gains to be had from removing the IHS completely, but it's a risky job and the risk outweighs the benefit in my opinion.

Well this CPU was like ~60 euro so no big loss if I do kill it when taking off the IHS ;) Then again according to this http://www.xtremesystems.org/forums/...d.php?t=132319 S939 chips are becoming rare now maybe I should keep it @ stock as a collector's item to make lots of money selling it :DQuote:

Some of these lapping pics are awesome. Last HSF I lapped was I think a GlobaWin, my current Theralright 947U is fairly flat but it it makes like 10C diff then I'm definately going to contemplate lapping the IHS and HSF when I move to C2D in a few months time :)
good god almighty ive never seen such sexy mirror finishes, dani your takin pictures with your processor half way down the block! :rofl:
