Yep, on this TRUE and W3520 I spent less than 2 mins each with 80 grit emery cloth on a granite surface table, with light pressure to get them "flat" then started working on the finish. It was the least tedious lapping that I have done !:up:Quote:

No offence, I like Austria. Actually my parents live right next to the border to Austria, but the best beer is and always was German. Sorry guys, I had to point that out. ;)
BTW, my avatar shows the Bavarian Royal Coat of Arms. ;)
No problem, I usually buy it from Austria, that is why I said Austrian. I appologies for my mistake, and hope to wash this off with...more Franziskaner :D:D:D
with all do respect sir, but i think this Franziskaner is the worst beer i've ever drunk dude. It's bitter and sour. Czech Pilsener is awesome no doubt but Franziskaner tastes like a cheap pisser IMO.
Good luck sanding. :yepp:
Although this is absolutely OT:Quote:

Sorry, but it's like saying that an apple does make a damn bad orange.
I'm not a beer connoisseur by any means, but even I know that comparisons like that show that you don't know what you are talking about.
Hope I won't get banned for too much OT. :D The initial questions in this thread were answered already, at least.
If you could find some spare arms and give them to me, then by all means :DQuote:

Let me point out some OT rules here:
- there shall be only beer discussed
- no one will offend any beer
- no beer is the best in the world
- small local breweries offer the best beer experience PERIOD (at least the one that I know personally)
... joking, lol
my god man invite someone over to help you I want to see this complete lol
QuadDamage - it's just a matter of personal taste bro. I love Weissbier, even maybe many people might actually find it a little bit to....insert word here :D
But make no mistake, I DID enjoy the Czech beer while I was in Prague, actually, if I am not mistaking, for a short period of time was there not a little overall growth in sales in...let's say...16-19th of April? Because I sure as hell drank a lot of Pilsner Urquell :D
I has a beer reading this! Do you has a beer?
My superior Canadian beer looks at your puny American beer and laughs.
I think it might be time to finish this project today and show some pics of the naked CPU to stop (or start?) the beer craze. ;)
Hope your arm will survive this.
Sorry for the late answer but I was having 4 beers while reading this and in the end I went to sleep :D
Ugh i'm comparing beer to... another beer and as long as it's called a beer it is fair to compare it to another beer ain't it. My point still stands, Franziskaner tastes like a cheap pisser - i don't care who brews it and where it is brewed all i care it's the taste and TBFH, i don't like german beer at all. And yeah i drink a LOT of beer from all around the world - start a beer dedicated thread and i'll tell ya what's good. Burp. :rofl:Quote:

Happy sanding:D
Yes, that is one version of Franziskaner ( I know 2 of them, darker and lighter). Anyway, please keep this civilised, everybody has it's own taste, it's your right to like or dislike any beer you want, but DO NOT speak this kind of words just because YOU do not like something. Franziskaner is WEISSBIER, it is not for everybody's taste, if you don't like it...well, you just don't like it and that's that...it does not match your taste. But that does not mean it's cheap pisser, and that is not nice to say. After all, you don't hear me saying that Weissbier is real beer for real men, not lady's :banana::banana::banana::banana:tail like Heineken :)
exactly
SMALL UPDATE
No, I'm not finished, sorry guys.
One issue I also encountered and forgot to mention is overheating. Even while handlapping the cpu, it gets hot after some time and I have to wait a minute or two for it to cool down.
Here are some shots for the one interested:
After first strokes. The outer layer came down quickly, can't say that about copper :brick:

Notice the small lines a drew to keep track of how slowly I progress :D

It will definitely be interesting to see the temps after IHS is off. Soldered ones that I have removed or seen proof of have had higher temps...but others may have different experiences.
The I7 STIM (solder thermal interface material) has a thermal conductance of ~87 W/M*K. The silicone die substrate around 120 W/M*K, and the copper IHS ~350 W/M*K. A quote from intel regarding purpose of IHS..."There are several technical and cost drivers to enable lidded thermal architecture such as minimizing the impact of local hot spots by improving heat spreading, increasing the power-dissipation capability of the thermal solutions, expanding the thermal envelopes of systems, developing thermal solutions that meet business-related cost constraints, as well as developing solutions that fit within form-factor considerations of the chassis. The primary role of the IHS is to spread the heat out evenly from the die and to provide a better bondline control of the interface material. This can be achieved by increasing the area of the IHS and by using a high thermal conductivity thermal interface material with low interfacial resistances."
The best thermal pastes have thermal conductance of 2-4 W/M*K, and inevitable microairbubbles in user application of non-solder paste result in piss poor heat conductance compared to intels stim.
Intels solution is a microthin stim that spreads the hot spots at a conductance of 87 W/M*K to a large surface area high conductance copper (IHS), prior to having to pass through the piss poor 20-40x less conductance user ptim (paste) application.
Removing the IHS, means you will now be trying to cool directly the hot spots over a very small surface area with 2 W/M*K, instead of first spreading the heat with 87 W/M*K solder tim to allow a large surface area to help make up for slow heat transfer of paste.
No question the older cpus that used crappy paste as the first joint would do better with deliding, because in that case you are simply replacing two crappy interfaces with one. But with solder, it is a different story.
Just wish someone who delids a soldered one, especially a hot i7, would make a video of computer running showing the delided cpu and screen with stress test and temps and vcore. Counterintuitive findings are simply harder to believe, especially when I have witnessed the contrary, not saying it is not possible, but would like to actually see it.
It will take 6 - 10 hours of lapping :D Hurry up man, we are waiting. ;)Quote:

Besides, I need an excuse to keep my Storm waterblock. This waterblock loves to get in contact with dies and doesn't like to talk much with IHS anyway :D
My left hand is K.O. because of the way you have to hold the cpu while lapping on rough surfaces. A nice comfortable holder would be nice :D Right arm, you're next ...Quote:

Definitely was not trying to dissuade, and very glad you are doing it...I am tempted myself just for learning, so I am very interested to see the results you get... just please post a screenie of load temps when your done.
Also, I think you are doing it the better way...by sanding you may preserve enough of edges to allow better mounting.
I little change here. I decided to make a more complex comparison by testing out just IHS lapped to about 3/5 of its height, then IHSless later and compare the results.
Right now, I gave it a nice finish of 800grit and mounted the original Scythe Mugen 2. After I set it up and boot, I will post results.
I apologize, because I leave to college in 4 hours. I am out of sandpaper, slightly injured and dead-tired (1:40 AM here). I will leave the CPU crunching for the next four-five days, let the paste burn-in, buy couple of 80grit sheets and finish it on Friday.
Know what might be better idea. Take a dremel to it for a little bit (to take layers off faster), then use sandpaper once you get closer to the core.
