making the i7 920 naked

[fallwind]

That's going to take forever + a day dude! I think most people who have used the sanding method have employed a power tool of some sort, like a belt sander.

Seriously though, just pop the IHS off. A pack of razors and a mini torch and you're in business. I just did my W3520 a couple days ago, easy as pie. I'm going to do some direct-IHS water cooling on it. Just waiting for my G1/4 tap to show up.

[posershadow]

Should have tried to mill it or something, take a few thousandths off on each pass and then when you feel you're close, sand the rest of the way.

Have fun with this and enjoy the project. (Get ready to write the check)

Unfortunately success insures nothing more than "bragging rights" at the expense of $300.00... Of course this is XS, so that may be important to you, but ultimately the risk will only yield 2 or 3 degrees at best for your efforts!

Non the less, looking forward to your results.

I like the idea of sanding it off, the remaining edge should supply good support for the H/S and help prevent crushing the core should the H/S get tightened unevenly. In theory you should cut through the face of the IHS, and still have the solder on the die. Did you measure the thickness before starting ? It would be interesting to know the actual thickness, or if someone has removed the IHS and has access to a micrometer to measure please post. Don't for get to shim the H/S to make up for the lost material, if you knew how much you took off, you could get shims of the equivelent thickness and remove the guess work.

the "Intel Core i7 - DO NOT REMOVE IHS!" thread is one of the reasons I am sanding it. Yes, the rest of the IHS that is left is going to provide protection while mounting or when uneven pressure is applied. Measured it, and the cpu with IHS had 4,95 mm (height of the cpu with PCB) , after 5 sheets of 220 grit I am only at 4,5 mm. I am going for some rough sheets, say 100 grit or similar like Dinos said, otherwise it's torture

Well, I don't know about you, but we sure enjoy reading about you torturing yourself.

Honestly: Trying to sand down an Intel IHS to the core, using 220 grit sandpaper was not a very smart idea, as some poeple already told you. But who cares. You learn from mistakes. At least I hope so.
Good luck with the rest of the IHS and some proper sandpaper.

Your'e not finished yet? More pics.

[vinister]

why bother doing it by hand either... there are tools for this kind of work. At least the first 3/4 of the thickness can be taken down in 5 minutes on a belt sander

[r1rhyder]

Maybe he's an apartment dweller like me and doesn't have a belt sander. But I would definitely run to work and use that one to take most of the meat off. Would save hours.

I would have to post pics with 0,03mm differences
It is slow, in the meaning of "WHEN WILL THIS END?" I kept sanding 2 hours after breakfast and than had to do a lot of work in the garden.

Tryed it with the one I have home and

• doesn't seem to do the job much quicker
• it has strong vibrations and I am afraid that might detach or loosen some SMD parts
• just after a short period of sanding with it, the cpu got really hot

To each his own, but after being a machinist for 27 years, I feel his only error was in grit selection. The risks are too high with a belt sander when you think of holding onto the cpu. Even if you had a lot of experience with one, you would spend as much time trying to make the surface parallel with the pcb after the belt sander, as he would sanding it down with quality 80-100 grit. Doing it manualy your fingers may tire, but when you are complete they will be the same length as when you started . With hand sanding there is no chance of launching the cpu into the wall/floor at 250 mph ! If speed was a concern, I'd opt for the milling machine to get started, but by the time you figured out how to hold it securely in the vice, dialing it flat, etc, etc, the time frame would be similar.

I'm not trying to diss you Vinister, I just wouldn't want someone reading this thread attempting to use a belt sander on their cpu without knowing the risks. If you have the skills to pull it off with that method, kudos !

Strip that sucker!

[s0lid]

One guy at here Finland have actually "lapped" his C2D cpu with CNC, yup custom made jig for that.
I bet it's damn fast to remove IHS with CNC

Such a shame that he isn't working anymore at at that cnc shop

[Aerou]

I have been used to lapping CPUs with 300 grit as a start. Never thought I would use under 150 grit, but after 5 sheets of 220, it was clear, that's not what Chuck Norris would use. So I went and grabbed 10 sheets of nice 100 grit SPOKAR sandpaper. My arm still hurts, but seems more that twice as fast.

Strip that sucker!

You brought some Czech beer with you home, didn't you? j/k
It is what I'm trying to do - strip it, but not tear it apart

[Monstru]

I tried to but the bastards took it from me at the airport =))

Fortunately, one of my coleagues managed to squeeze a 5L keg in the luggage

[r1rhyder]

While we're waiting, tell me about this Czech beer. What's up with it, is it that good?

[Jamesrt2004]

the best beer = czech!

[matsjuw]

Oh no no no, Belgian beer = king of all beers ...

[Monstru]

Well, I like beer from Austria most, but Czech beer was also fabulous

[r1rhyder]

I drink mostly Grolsch and Heineken, so is it alcohol content or taste or both that make the Czech beer so good? I'm in the states so most domestic and imports are ruined by the preservatives they put into them. No purity laws.

[Monstru]

I like the taste, that is allways what I am after. One of my favourite beers is the austrian weiis-bier Franziskaner for instance

[Aerou]

No that's the best kind of OT I can think of, honestly.
You can't say this or that beer is the best, but certainly Czech has one of the richest tastes. Also, it heavily depends on how you get it. My personal favourite is Pilsner Urquell, amazing beer. IMO One of the things a man should experience in his life is getting mesmerized by a pint of fresh, unprocessed Pilsner directly from the brewery. It is mindblowing and I am not exagerating. Believe, since I study there and it serves as my petrol in the hardest of study hours

[r1rhyder]

I'll have to find a distributor here, they even have pouring instructions on thier website. Too cool.
