My first lapping over 400grit, time to break out the last of my as5 :D

I don't think that using AS5 on such a polished surface is a good idea. I mean AS5 won't perform better than a silicon based thermal paste when the surface roughness is so low. Try it. ;)
well, the paste in the pic tells me contact is good, maybe no paste, is there any advantage at all to using any particular kind of paste after mirroring? I guess I'll go find out :p:
Yes, there is. There are still microscopic gaps that need to be filled to get the best possible thermal contact. You just have to find the paste with the right particle size. ;)
AS Ceramique on a 600 grit finish is about as good as it gets!! Its about the best match for its particle size.
Said the lame lapper :D
Well Cathar said it too but who's listening? ;) This is about performance & beauty, not just performance ;)

:up:
any way to unlid an e6400? otherwise, i may have to lap also... but i always unlidded my s939 CPUs... this is my 1st core2 chip.
Sure ... smear a bunch of AS5 in the bottom of a frying pan ... smack your CPU heatspreader down on the AS5 and slowly heat the pan until the solder pops.Quote:

I remember reading the C2D's IHS is soldered, so it's not easy to "unlid" it. Actually, you may well break the core while "unliding" it...Quote:

I'm very careful with my work... I may just want to give it a shot if indeed it's nothing TOO difficult for a modder to do. I've done my fair share of popping lids on A64s, and my fair share of customized mods... I feel like I wanna give it a shot.Quote:

Let me know if you find the thread. Thx. :)
Godman, IIRC removing the IHS on C2D chips doesn't help temps versus lapping.
I think all the copper from the IHS is more beneficial than not having it at all.
The IHS is made of copper underneath and what, nickel coating? I guess I could lap it... I've lapped my fair share of heatsinks, but wouldn't I have to wet the sandpaper? I don't want a WET cpu!! :(Quote:

Lapping is really extreme of extreme... but if u get results go for it, just be carefull...
You can do wet or dry, depending on how long Taffer keeps his avatar IoI
But aside from joking, its a personal thing , some are more comfortable with dry some with wet lapping, and i dont think u can dammage your CPU if u let it dry sufficient enough...
I wet lapped mine and if you take precautions like having a towel nearby and tapping the cpu on it after every couple of turns you'll be just fine. :yepp:
Well, I lapped my 6400 with great results, gained another 200MHz stable, and about 8-12c cooler at 1.5v, also stabilized the cores running at different temps, also lapped my HSF.. AS5 worked allright with it I think, and hmmmm... yea, wet sanding the whole way, DON"T worry about getting it wet, just make sure its dry before you turn it on, I waited a day, my bro used a hair dryer...
Here's my chip hope u like it :D
For this lap job I used the stuff they use 2 polish contact lenses.
I haven't used it since the lap job, still waiting 4 my TR ultra 120 X
omg she has a six pack :p:Quote:

Does anyone find it offensive? I had one person request that I remove it and put up something a little more computer geeky. I hope you all do not mind that I never found the time to anwser his request.
I've got a degree in computer electronics technology and 99.9% of the time, water will not hurt electronics at all, so long as they are not under power while wet. If you dry them thoroughly first, you should be fine. The same goes for cell phones...if you drop one in water, remove the battery ASAP and let it dry. I would try my best to keep water off of the contacts (and use the black plastic that covers the contacts as well) anyway just to save the hassle of cleaning them, but some good, high percentage alcohol (Johnny Walker & Jim Beam etc. do not count) should clean it up nicely. Just be sure to use some form of lint free cloth if you do, and pat it dry instead of wiping just to be sure you don't snag the edge of a contact and ruin your day. Always better safe than sorry. :yepp:
:off:
Oh, the cell phone tip...there is a white indicator near the battery that turns pink or red if you get it wet...so there is no need to lie and say it did not get wet, the proof is there. The last time I did that was winter so I hung it on my car vent, turned the heat all the way up and turned on the AC to lower the humidity to allow for faster evaporation. Worked like a champ.
I like it :)
I just experimented with metal/metal contact on my Freezer 7 Pro @ 600 Grit and lapped E6600 @ 15 Micron.
It actually RAISED temps. By 6C -- from 32C to 38C idle. It used to be seated with Arctic Silver Ceramique.
The paste is not suitable for surfaces with such a low surface roughness. ;)Quote:

First sorry if I raised and 'old' thread up. I lapped my E2160 today and there were no decrease in temps or they might have rised a little bit. I used 400->600->800->1000 grit sandpaper for the lapping and I had a mirror as a base for the sandpaper. Used enough water for the paper and everything seemed ok. Used the 400 grit paper to get rid of the nickel on the HS and then finished it with the higher grit papers. Of course the HS didn't have a mirror finish but I thought It was ok as freecableguy used just 600 grit paper to finish the HS in his faq. First time I mounted the boxed heatsink the cpu and cooler had no contact whatsoever and temps were very high. After that I remounted the cooler and it seemed that it had a decent contact but temps were not better. Can somebody tell me what might be the reason for the crappy temps after lapping?
QX6850 i got about 3C lower @ full loadQuote:
