Holy Crap! Did you know there are "Delid Tools" out there?

Yes.. Doesn't everyone?
 
Yes, it was news a few months ago. They're a bit pricey but it's a nice idea. Not sure if it's worth it if it's a one-off per CPU package versus the services now being offered by Silicon Lottery.
 
agreed, silicon lottery is cheaper.

actually, on second thought, this one might be cheaper. it's just two bits of plexiglass.
 
Last time I saw anyone selling delidding devices, they went for something like $50 a pop. Maybe if you were going to delid multiple CPUs it would make sense to get one.
 
I saw the plexiglass version when the video released in January but I haven't been able to find a place to purchase one.... Not even on Ebay. Not interested in the expensive aluminum de-lid tools.
 
Alternately you can save money by purchasing an expensive 3D printer and 3D printing a delidder for little cost. ;-)
 
I delidded two GTX 570 GPUs... I used a Hot Air gun, and the glue got so soft the razor blade wasn't even needed... They just popped off like they were held on with mayonnaise.

I don't know about Intel/AMD CPUs but the adhesive on those GTX 570s were pretty soft at 90C.
 
That's pretty cool. But I always thought whatever was underneath the lid would be cooler.

Why would you want to delid your cpu?
 
Delidding tools are an interesting niche, I like the twist method with those paddles, it's probably much less pressure on the PCB than than just pushing against one side (basically modified vice method).
But I wonder why people haven't tried to re-solder the lid with just pure Indium wire. The myth that this isn't somehow possible has been debunked, so it's just a matter of figuring out how to do it.
One could try to unsolder old CPUs and keep temperatures as low as possible, or at least figure out the gramm amount of solder needed, given a certain die size and IHS distance. What's the big technical challenge, stumbling stone here?

Probably the same reason I delidded the GTX 570s... Thermal problems not solved by cleaning fans/heatsinks due to thermal paste under IHS getting old, or air seeping in.

As soon as I delidded, swapped thermal compound, relidded temps went back to stock.

I assume CPUs could have the same problem, or maybe you want to water cool directly to the die for overclocking?

This is why you buy a CPU with a soldered IHS 😛

Except Intel found a way to screw that up, too.

It appears the thickness of the solder and/or some other factors make it less efficient at heat transfer than CLP/CLU.

5960x delid: 9C max decrease, 7.5C avg decrease.

6950X delid: 6C max decrease, 4C avg decrease.


Not the same kind of gains to be had delidding a 4770k, but if the hottest core on my 5960x dropped 9C, that would be huge (The hottest core on mine is 12C hotter than the coolest).

Not sure I would want to spend the $120 or however much it's going to sell for, but it's a very tempting concept.

Delidding a HSW-E/BDW-E is much tougher than the non-HEDT CPUs. That metal epoxy stuff they use - it's not EXACTLY solder - is hard to remove.

With the Delid Die Mate Extreme it looks pretty easy. The tool isn't going to be cheap, though. And the risk is definitely increased in the chance of destroying the cpu and the monetary risk.

This is a great idea . . . for 4-core mainstream chips like the i7.

The *-E chips used to use solder. Intel has cheaped out on us and gone to epoxy now. Yuck.

We buy them for about $80 here after currency conversion, they sell a socket frame to hold the delidded cpu in place too.

The Delid Die Mate and the Delid Die Mate Extreme are two different models and the Extreme version is not available yet. I have not seen any announcement from CaseKing or Der8auer about pricing.

The Extreme one is clearly physically larger, so I would be surprised if it did not cost more. It may carry a premium as it's for the E series, as well. $100+ would not be out of the question, IMO.

Did you watch the video I provided? It shows a pretty darn easy E series delidding, and it's not the only one the guy has done so far.

i never really liked this method of delidding...

i always just took a razor and cut along the rubber seal it had on the side, then use a plastic shim to pry the top off.

You can now get those plastic shims on amazon as they are also called cell phone repair tools.

Thanks for sharing this. That video is the most hardcore delidding i've seen yet. And there is a lot of interesting stuff there as well. The IHS is plated with gold to make In-solder stick, that's cool. Why wouldn't it stick to Nickel-plating? I guess all those surfaces have some kind of oxide layer, or maybe they get one when the lid is heated to ~180°. Or maybe indium and gold just stick well to each other.

Don't believe what Guru3D parroted from OCDrift. There is no such thing as a metal epoxy, unless it's an epoxy that is used to glue metal. A metal is something with a reflective surface that conducts electricity, epoxy also has quite a narrow chemical definition, even though it's often used as a synonym for strong glue.
The CPU uses both solder for the die and some kind of rubbery glue, resin or epoxy to connect the lid to the PCB. You can see the metallic solder on the bottom under the die.

Apparently it's better to use shearing force to remove the solder from the cpu, rather than shimming and prying it open . Many wire cutting tools, (scissors) use shearing stress after all.
