Sanded down the IHS of a Q6600 to the silicone.

[PVTCaboose1337]

I am looking into this "photoshop" thing. I have looked at the picture of the CPU with the half circle reflections and found that both sides are not the same. This means the picture is legit.

 

[OzzmanFloyd120]

What about the bright pixels in the shape of where the IHS used to be in the lapped shot?
At first this seemed amazing, but now I'm starting to think it might be a hoax.

 

[The Haunted]

Do you know if anyone else have tried this sanding method, id like to know if the chip have a good chance of survival.
I must get rid off this useless ihs as soon as possible

This is how much you need to take off. I have a celeron that i might make a ginnypig and take it to a power tool carefully...

he never said that was an actual pic.
he just said that's how much needs to be taken off.

 

[Ruslan]

This is the same pic shopped, just to give you an idea of exactly what you are facing when if you decide to attempt this. I guess i should have mentioned it at the time of the posting to avoid the confusion.

Niiiiiiiiceee... I need to do this to my quad... Maybe then I would be able to hit 4GHz. As it is I'm doing 70-75c on air at 3.6GHz 1.5v with a Tuniq tower. If your mod cut down 10c... dang.

I'm honestly trying to figure out why you were so hot before the super lap...

My x3210 2.13 @ 3.2 doesn't get to 50c under load without being lapped....
But nice job for sure, I'm not considering buying a new cely just to try this out.

Some are just like that. I remember the second X2 3600 that I got didn't run for shit, temps were off the scale, so I popped the IHS and found no thermal paste at all between the IHS and the core. Once I did that, my temps were good.

 

[Ruslan]

This image is a photoshop right? There is some weird shadows issues

That is just to show how much you need to take off nothing more LoL.
I didn't take a side view from all the excitement.

I want to do this to a E7200 I got...hmmmm

 

[thebeephaha]

If you get good at this you should consider doing this for a fee for others too afraid.

The IHS does not get mounted perfectly so there could have been a gap between the core and IHS. If you look at the firs pic you will clearly see the Intel TIP getting scratched so it is not a thin layer under there. some chips have less space there than others I guess just like some tops of the Ihs's are perfect and some are just plain bad.

It looks like there's some light scratches on the cores, I'm shocked it still works.

They are a bit tougher than you might think. That same X2, I cracked the edge of the core with my HS and it still ran for a while.

 

[Wile E]

I still want to know how you did this without damaging the cores.

You can actually sand the cores themselves anyway. There is a lot of material on top before you get to the actual silicon itself.

One member of this forum (curt, iirc) actually did sand the core of his opteron, because he wasn't happy with the temperature difference between cores.

I'll edit back if I find it.

EDIT: Found it http://forums.techpowerup.com/showthread.php?t=40276 I think he gets into around page 2.

 

[The Haunted]

What about the height of the circuitry near the core, they look easy to damage while sanding.
And is there another way of removing the copper powder from those aside from arctic clean?
I will try it on my brand new e8600 when i have the time, i once removed a ihs on a 4400+ but this is really hardcore congrats.

I'm sure there is something else to clean all the powder. It clumps together and becomes paste when exposed to moisture. Things get very messy after a while. I should have take more pics but I my hands were so dirty I didn't want to touch anything. I just had AC on hand so I used that. Use a tooth brush with whatever liquid to gently brush anything off. You could probably just take it to the sink with a tooth brush and just brush it iver flowing water, I did that a few times in the middle of the process.

Thanks for that link, Wille. I'm shocked so many people were flaming him for taking a risk with is CPU, but I definitely understand how much tougher the top of the silicon is now.

 

[Ruslan]

LoL, I knew that the top of the dies is very tough otherwise I would not risk it. I thought people knew that, I guess I didn't think about it. And I'm thinking why do so many people think this is prohibitively insane. The craziest thing about this is not the risk it is the amount of time you spend on it. There is very little risk if done right.

 

[ascstinger]

just thinking a bit, you could probably use power tools without risk to sand the ihs until it is near the point where you break through, then finish it by hand

I *might* try it on an e6300 laying around if I have the time

Ya I follow that and honestly with the new Core2's and Quads people are seeing really good results from lapping, I can't believe I have been too lazy to do it, the average surface is not very smooth or in shape at all...

I would worry about using power tools for this because of excessive heat build up

Here is a link to a post on XS with a guy that did the same thing. His CPU is also alive. Someone at occlub touch I killed my cpu, well here is someone else that copied what I did to a 45nm cpu and it's not dead.
