Q6600 G0 lapping thread.

lapping a c2d is easy, you don't have pins to worry about....unless you're an incredible moron :confused:

you can't really fubar this up.

scoobie dave - negative on the brasso mate, it looks nice but it might actually hurt your temps because of the chemicals in the oil which won't rub out.....i'd relap with some 1500 again.

Yup. Using any form of polish is a bad idea as it will fill in the tiny crevices where the thermal compound would go. Don't worry about the odd scratch. Like marscay says give it another rub with 1500 or clean it of with some IPA.

Ok mate I will do that, I will try and get some 2000 grit and finish it off for a better shine then. Or I will just give it a good clean with some TIM.

How much artic silver do you normally apply to your quads? Personally im putting 2 thin lines vertically across the cores.

Used wadding on my E6600 which people could argue about the same as the brasso...but results speak for themselves...after lapping and polishing a 10c drop...who could argue with that!.

...not disagreeing just posting my findings!.

@Scoobie Dave...just scrape a very fine layer on with a credit card or similar...as you won't need as much now it's flat.lol

w3bbo · 6 Sep 2007 at 17:37

The thing is any oil and residue will act as a thermal barrier. So while polishing it looks good for the pics it won't help temps at all and will most likely damage them ever so slightly.

I use the 'credit card' method. I use a razor blade to spread out a very thin layer over the IHS. As the cpu is lapped the thinner the layer the better as there aint much crevices to fill in.

Agree...but wil it make that much of a difference if i went through the bother of sanding my cpu again...that's the big question?

....i think the answer would be maybe\maybe not.

Hmm, after you use Polish with Silvo or Brasso to get rid of Lappings Swirl marks, not just make it shiny, you do actually clean it throughly with ISO PROPYLN if you have any common sence, you do not leave the resindue on it and apply AS5.

vocch · 6 Sep 2007 at 18:48

Hmm, well i guess you tought a few on here a new lesson there then but that's not the question...and although i now enough about lapping done 3 cpu + heatsink and obviously read the guides first!....what i am asking is what's the BIG difference is it going to make!...if any!

helmutcheese · 6 Sep 2007 at 18:51

BTW, Lapping was not invented by some Leet 18year old Geek who wanted his CPU to run cooler, Its a Engineering Process and I lapped valves in massive Diesel Engines I rebuilt for 16years.

As to what diff it makes to above, very little but you are lapping in 1st place to gain a 0-10C drop, so whats 5-10mins more work to get rid of swirl marks and also add bit of bling, you will never ever get it so flat and shiny that the TIM wont stick as some claim, you would need see a new Razor Blades Edge under a Microscope to see why.

vocch · 6 Sep 2007 at 18:53

And...still waiting for an answer?.

And like i said i got a 10c drop without using ISO PROPYLN ...so what's the big deal...imo NONE

You really dont have a clue, I was refering to the comments about resindue been left on after polishing, in the quote from another peeps post you quoted and agreed with.

Yep...it's called a paper towel..done a great job and who are you to tell me different...10c drop and the proof is in my post not just talk...i do agree with on a scientific scale...but what is the difference 0.0001c

IMO...not worth arguing over.

helmutcheese · 6 Sep 2007 at 19:08

You really are clueless, you asked a question, I gave you a answer, and I am a ENGINEER who did lapping when you were still on the Boob getting Milk so I can tell you about lapping and cleanlyness of parts.

You aint supposed to get grease from hands on AS5 (site states), it dont mean it will actually affect temps, its just not good practice nor is leaving resindue from polish, and a paper towel wont remove it without some cleaner on it.

What you say is true i agree...and imo makes no difference to temps in the real world.

ps.You must be very old then lol.

I agree with the not polishing or useing anything that might become a barrier for heat trans. lapping is everything on a set of valves for any engine as stated above, and after all the hard work lapping might awell get optimum heat transfer by not useing any kind of polish.

and on a diffrent note, ive also got better temps useing artic ceramic rather than As5 ive tried the edge of credit cards and stanley blades but Artic ceramic always comes out better temps with me.

also great work on the ICH's and heatsinks guys, they look real good and can only help in reducing the temp's. even a 3c drop is worth the effort i think.

kirkster · 6 Sep 2007 at 21:05

Can we get back to the point guys...

How exactly do you do the lapping? You get the grades of wet and dry first. How do I hold the chip when doing the lapping? I mean, anti static and all that. Not familiar with Core2 Duos but how do you avoid fouling the pins? What device do you use to hold the chip whilst rubbing it on the wet and dry?

I've just bite the bullet and did my B3 @3.33ghz.

My main aim was to see if I could reduce the huge difference between the cores.

And Halfords had no 1000 grit so I just did 400 and 800. I'll probably finish it off it when I go to sell it.

Forgive the crappy Nokia pics-
