well you see, that's the thing - I'll check with the razor next time round.
Out of interest, with what did you lap it with? Which sandpaper?

For me - I have a "scratch" on my Antec 920 - which might be causing the temps to be inaccurate.
Might just go head and RMA it, if it is concave/convex.

Yep, lapping effects do vary. If the IHS is flat, then lapping it may only gain 1-3C for all the effort and not be worth it for some. But if it is concave, then it can mean much larger gains.

As for sandpaper, if it is very concave inside the IHS and lots of sanding needs to happen, then start with some 400, then move to 600, and then finish it with some 800. If it is the top, then you can continue with 1000 and 1200. Mainly little temp diff going from 800 to 1200, but it makes it look better! Some like to go up to 2000 or even 3000 to make it like a mirror finish. I just wanted the temp improvments so I stoped at 800 inside and 1000 on the top.

Good place to find sandpaper is at auto parts stores, although ebay has it to.

Basically to recap - the delid went well, as my pictures show it doesn't look bad. I removed all the glue that was at all possible with a credit card, I checked and I don't think it would be possible to remove anymore without some other method. I don't feel any glue left so I think that it is as good as it can get.

For reference, here is my post with pics:
http://www.overclock.net/t/1313179/official-delidded-ivy-bridge-club/10650#post_19193615

I put too much ultra on the die and on the top of the IHS, so in a 22.2c room with 1.29v I was 82c before and 72c after.

Then the trouble began, I took it all apart and made triple sure that I put just a very fine layer of Ultra on everything, in no way could it be too much, but it had a nice even, thin coat. Temps went up measurably, so I started all over again. The only possibility -> too little Ultra.

I had just enough Ultra left to start fresh, clean everything, and reapply Ultra on the die and on top of the ihs, just like the Coollabs video shows. I looked at a lot of pictures and I am as sure as I can be that I did it right. Temps ended up higher than when I had too much, but better than too little. Now I am out of Ultra so I try the only thing I have, AS5, and that is useless, so I can't be overclocked for now.

My trash comment was out of frustration when I realized that all the time and money put into a $229 chip after I try lapping everything, I could have just bought a 3930k. Then I remembered than I am doing this to learn, and reminded myself to not be such a whiney douche.

I found a nice razor blade that looked as level as possible. Put it on top of the ihs with a flashlight behind it, then had my wife look also to make sure she saw the same thing. Unquestionable, unmistakable light in the middle = concave. A lapping we will go, a lapping we will go, hi ho the dariy-o a lapping we will go.

Well, cool justanoldman! Thanks for your recap above. And it is great you found the reason for the dissappointing improvements. We can have some good hopes that you will get this completed with the results we are used to seeing and that you wanted and expected. And it is the fun of doing this mod anyway - that is a large part of why we do it. Keep us informed of your progress and if you have any more questions.

Thanks a lot for all the help.
What did you use that was flat and round for the underside of the IHS?

I would just keep the Ultra on the die until you can get some more. Also I wouldn't waste the CL Ultra/Pro on the IHS, just use some quality diamond based TIM for that. Run down to Best Buy or Staples, they sell Antec Formula 7, great stuff for IHS and coolers.

Quite the persistent legend you are!
I would give you a rep - but feel that you're counter would be going un-unique too much tongue.gif

Thanks PCwargamer for the info on the sandpaper +rep!

So I decided to go "au naturel" , "buck naked", "direct-to -the-die" today. Why do I do this to myself? I got a great chip already, but I just can't leave well enough alone. Computer wouldn't boot, getting post code 55 and that major sinking feeling in my heart. doh.gif My first thought was that I over tightened the water block. Took everything apart, and no bent pins. Turns out I didn't tighten it enough. Everything is working now, hopefully better and not worse. I documented everything this time and will post my results once my body stops shaking.

My half dead chip gave the exact error on post at his last 10 minutes...i remounted it with ihs on but internal gpu was gone already. I advise you to check iternal gpu. remove external vga and boot from internal gpu install drivers and see everything okay ? my half dead chip was working with drivers unistalled or disabled from device manager

Anyway i used phobya LM on cpu die, gelid gc extreme on cooler and tested at 1.176V at 4.3 ghz( I couldn't go higher with intel stock cooler cause it wasn't stable due to heat and i can't compare higher clocks,voltages and temps at 4.5 or 4.6 ghz)




Before Delid Room Temp 22 C



After Delid Room Temp 21 C



19 C max and 18 C average before-after.

I won't touch the cpu from now on smile.gif I can't kill this too biggrin.gif
