Delidding an Intel 11900K

[TeaLeaf]

So it seems delidding is still worthwhile, but damn has the the process got more complicated and difficult! :crazy:  

Back in the day (e.g. i7-4770K) when intel used good old hopeless goop to stick down the IHS the whole delidding process was relatively straightforward.  But this indium solder is just plain nasty to delid.

I doubt I will ever dare have a go myself. I'm assuming that it's a better process from Intel that makes it more tricky?

I wonder if The Chaos Method of just whacking it with a hammer still works?

TL did that first, and myself shortly after. 4770s, IIRC. Mine is still working nicely in Jasmine's PC. This was back before it was a common thing and the best way was to hold the CPU's PCB in a vice and whack the heat-spreader until the glue broke. Now there are little devices, mainly made by the chap in that video, to do the same thing but with less room for 'user error'. With these, delidding became very straight forward... until Intel went back to solder. Now I don't think its worth it for most people, as it is a lot easier to damage chips in the process.

Edit - and as if by magic, I stumbled upon this right after posting --

I remember doing my 4770k in the vice a work with 2 piece of steel to act like these new devices. I was totally bricking it. But worked like a charm. Was it worth it, probably not given the risk at the time.

The oven trick is pretty straight forward, even easier with a hot plate. Melt the indium and pop the lid off. Silicon Lottery had a video showing their method and it really is straight forward still.
Romans metal fatiguing technique always scares me. That's not the way

Ovens are for Pizzas Mike, not CPUs.

:norty:

I can't remember the gains with a delid on these chips. Surely the whole point of the solder is better heat transfer? I am just not sure it would ever be worth it, for most of us  - even including those like you and I who are keen to push mhz and voltages.

Doesn't stop it from being fun for the insane few like roman, of course. But he also doesn't pay for the privilege!

A delid on the old 4770K typically reduced temps by 20 degrees C or so with a range of +/-10 degrees.  The results were dependent on the quality of the thermal goop and glue applied to the CPU you had and Intel's QC didn't seem to be the best at that point, hence the highly variable results.  

The 11900K delid reported a 10-12 degree reduction but I've not seen anyone reporting the larger 20 degree reductions, which I suspect is due to (a) the solder being better than the 4770K thermal goop and (b) Intel's QC being better on the solder & IHS application.  So the Intel delid doesn't seem to give you as much of a boost today as it used to, but still a pretty significant improvement.

Whilst Intel's IHS applications continue to show considerable variability in effective cooling performance, AMD seem to be doing much better and have been producing much better results with the AMD IHS than Intel see with theirs.    Since Ryzen came out, delidding a Ryzen 5/7 etc seems to only give you 2 degree improvement, which indicates AMD has done a much better job with the application of the Ryzen IHS and materials used. So delidding today's Ryzens is probably not worth it at all.

I don't think I'd bother for 10 degrees... that could probably be achieved by other means too... still... ask me if I ever end up getting one, the answer might change! :lmfao:

The 4770K I had to do, it was hitting 100 even with minimal OCing, which is no fun at all. My 8700K I probably could have done without, but headroom increased massively with the delid so why not eh.

If I ended up with one for free I would absolutely give it a bash... I mean err, a roasting. Bashing was last gen.

I owned a 4770K for a number of years (5+) and overclocekd it fine to 4.2GHz and ran under 60 degrees at full load with a Corsair H100i cooler. If you got 100 degrees you must have been keen on a 4.5Ghz clock.

I think we have different definitions of full load. No chance a stock 4770K would run at 60 degrees under an AVX Small FFT prime run with a H100i... it just wouldn't happen. Gaming maybe, but gaming is a relatively light load even when your PC tells you you are using 100% of the CPU. What that 100% is makes a huge difference. They were notoriously hot chips, and the reason delidding became popular in the first place.

The 4.5Ghz thing you are spot on with, however. :lmfao:

Gotta say, I do use Prime 95 with lots of variants for stress testing my CPUs. I tended towards SSE rather than AVX but all the same I pushed the CPU through 24 hours of stress. I never had anything like the temps you're suggesting and even now my buddy who took the 4770K off my hands still keeps the same overclock I had and it runs very well.

I'm no expert but I do read up on how to before testing. Not saying I didn't di it 100% correct but for sure I never got 100 degrees.

I would say that 10 degrees if it is pure reduction due to delidding is rather good, worth it for sure if the method isn't that horrible physical beating thingy.

[Chaosphere]

Fair enough mate. You also have to use the smallest instructions in prime to get the max heat and strain on the cores. Blend doesn't reach the same heights. A CPU could easily pass 24 hours of blend and fail within 30 minutes of an in place small FFT with AVX instructions. I'm going off of my own experiences, but also plenty of other people online on various tech and OC'ing forums moaning about the temps. As I said, it was these chips that made delidding so popular!

Always possible you had a golden chip of course, and no doubt as you have said I was keen on pushing it faster - its currently sat at 4.7 in Jasmine's rig.

As for 10 degrees being worth it... perhaps, but man I just don't like the idea of roasting my CPU in the oven to get there! Doesn't mean I wouldn't necessarily end up doing it... I'd just have to stop and convince myself a bit more first, I think!
