Guide - i7 3770k / 4770k get's LapPeD & DeliddeD.

post #1 of 125
Thread Starter 
I just want to share this since I lapped my old fella 3570K 4.7 @ 1.34v temp's dropped very much top was 65 under heave load smile.gif in my loop. I decide to follow the same path for my new 3770k biggrin.gif

I have seen many video out there using a bunch of sand papers with various grid. and ppl making video part 1 and part 2 to finish the work. I did it in half time and it does worked very well for me. you just need to do it right not just slap the CPU in the sand paper and go back and forth yessir.gif LOL.

Here is the material list .

CPU biggrin.gif
Blue Tape
skyn3t logo rolleyes.gif
Arcticlean 1 & 2
Brasso silver polish
100% cotton rag. "old shirt"
Flat surface like , Glass table, mirror or even the glass from the photo frame with you picture when you was a baby running naked tongue.gif
Sand paper grit 180
Sand paper grit 220
Sand paper grit 440


Part I
Material forgot to take pics from my sand papers sorry tongue.gif






Preparation : I just come out with this idea, just to be sure none of the sand paper and the copper dust won't get into the small chip in the back of the CPU. "Precautions"

tape the back of CPU make a clean cut like it show below


fold the edge's like so.


Now is it protectec thumb.gif


Now is it protectec thumb.gif


Draw a two way arrow, following the DIE direction.



Part II 180 Grit
Time to work easy not too much pressure only hold it down let your arm sit a bit on it and back :yessir and forth : 180 Grit
12 section of 50 sanding down+ total 600 times back and forth.
Alwasy follow the arrow












After 600 pass sanding on 180 grit. The 180 grit won't scratch too much deep, you just need to stay in the same lane all the time "don't clean the sand paper dust let it be" remember to work easy. this is the result a got.after 1400 pass blinksmiley.gif


Part III 220 grit

I wrote "A" and "B" to the arrow so just to no get lost wink.gif




result after 1000 pass with 220 grit, just to smooth the 180 grint and work very easy on the flattering surface.


Part III 440 grit

This is how I did mine you may disagree with it but I found it way better than just use the dry 440 grit till you smooth it out on almost mirror finish.

The first 400 pass It was drye sand paper.
After 400 passI put two drops of "ArticClean" in the sand paper, pic below show different thing tongue.gif. I was going to drop and a sprayed the thing a quick paper towel to fix the mess.


here is the result after 1000 with two drops of "articClean" pass with 440 grit. total pass 1400 blinksmiley.gif




Part III Polishing

Brasso Silver polish
100% Cotton rag
Glass surface.

here you work until you get the result you want, Polishing part is optional but a very clean copper surface polished does look way better. wink.gif








Final part testing temp's

It may not give you the top temp drop but is does make difference. Few "C" drop's is always welcome
Thermal paste used IC Dimond carat 7, This is the best thermal compound I have used for years no cure time temp's drops right after application and test.

Now Is Delid time, I think I'm mad today,rolleyes.gif

Tools list
skyn3t logo tongue.gif
hammer
CPU
Tiger wood - Why used tiger wood? have a look here and you will know how hard this wood is. since I work with wood we have tons the shop.
WOOD SPECIES (Hardest to Softest) chart



I had to use bamboo Dish plate holder it is about 1/16" of a inch tick to lift up the first knock down wood peace.
so this way the IHS CPU can stay firm the the first peace wood like show in the picture below and the PCB stay on top in the knock down peace wood. I cablled It t" knock down" is because I going to use that peace of wood to hit with the hammed and remove the IHS out biggrin.gif


different angle just to have idea what I'm talk about.


It toke me tree hit to remove it, it is very easy and 100% fool proof tha you not going to damage the PCB and trash the CPU after using razor blade. a lot people are using different tolls to remove the IHS with the same method. I was afraid to put my CPU in the Vise Clamp.


wheee.gif


wheee.gif






Look how shine the DIE is smile.gif can you see my camera lens ? tongue.gif






Now, are you serious Intel? How much crap you put under the IHS LOL , the money you safe in the thermal paste you used in the GLU to hold the IHS in place. lachen.gif




Hey this is the temp after the delid process.
Thermal paste used on DIE and IHS is
IC Diamond Carat 7

wPrime before Lapped



wPrime After Lapped


wPrime after delid biggrin.gif

I see you use artic clean and I"ve heard using 90% alcohol works just as well but i was wondering about acetone? Has any one tried using it as a cleaner solvent when removing paste?

Acetone can eat up the pcb layer.
