Recap: When Intel introduced Alder Lake last year, some users quickly noticed a fault: the new socket's integrated loading mechanism (ILM) pushes down on the CPU from only two small tabs, causing it to bend in a way that separates the CPU from the cooler and increases its temperature.

In January, Buildzoid from Actually Hardcore Overclocking developed a straightforward solution: adding thin washers to the screws between the motherboard and ILM that reduce the pressure exerted by the ILM to a level that doesn't bend the integrated heat spreader (IHS).

Igor's Lab tested it then and found that it offered about a 5° C temperature decrease with the 12900K. It became the de facto solution for overclockers that didn't want to delid their CPUs (a popular option with the 12900K), but because it also reduces socket pressure, it can cause minor problems.

Thermal Grizzly is now producing a more polished solution in collaboration with legendary overclocker Der8auer. It's a Contact Frame that replaces the stock ILM and provides even pressure to all four sides of the CPU. It's also able to deflect the tension in the IHS to the edges, improving the contact in the center between the die, IHS, and cooler.

Stock ILM

Der8auer made a video about the frame before it was released, which explains how it works in more detail. In his testing, with a lapped EKWB Magnitude water block, it offered a 7° C temperature improvement at best and 3-5° C of improvement in most cases, depending on the CPU he used.

It turns out that the helpfulness of the Contact Frame varies with the CPU and cooler depending on how flat they are to begin with. Some CPU coolers made for Alder Lake come from the factory with a slight curve to balance out the bend in the IHS, and Igor's Lab's recent review found that they don't benefit from the Contact Frame.

In their testing with three different models of CPU coolers, Igor's Lab discovered that the frame offered an improvement of 10° C with one, 6° with another, and had no effect with the third. However, the best two temperatures they got, roughly 60° C, were with the frame.

Igor's Lab also tested another solution, the Alphacool Apex Backplate. It supports the socket from underneath and makes it more rigid but isn't quite as effective as the Contact Frame: in testing, it only offered a 5° C improvement. It's also only compatible with Alphacool hardware.

However, the frame isn't necessarily the better product. Both Der8auer and Igor's Lab warn that it can apply too much pressure to the CPU in the socket, causing it to make a bad connection to the motherboard that can often result in memory instability. The solution to this is to reseat the memory and dial back the pressure by loosening the screws, but it's tedious.

The Contact Frame also runs about €40 ($43), which is a lot for a small aluminum bracket. The Alphacool Apex costs about $15. If you are finding that your 12700K or 12900K is cooking, though, picking one or the other up -- or even trying the $5 washer trick -- might be worth it.

You know, you would think that with so many chances, intel refreshing their socket each other generation they would get stuff like this perfectly optimal since they are always able to refine it but no, apparently a socket design that's apparently efficient at cooling is too much to ask of them.

A 5Ghz Dualcore Sandy Bridge on a 3nm node would be what........3 to 5 Watts ?

You could lower the temps / lower the power consumption and I could boot to Windows XP

Win / Win / Win

Although, Windows 11 runs fine on my Sandy as well if you'd prefer a backdoor'd Spyware Platform that limits what you can and cannot run on "your" system (LoL)

Win / Win / Lose

Up to but maybe not so much, maybe even close to nothing, maybe causing instability (worse than nothing)

Sounds like a legendary product.

This is a post I made yesterday on somewhere else, I'll just copy/paste it here too:
I have many many issues with intel, added over the past 10 years about how ******* they are, but one of the latest nasties they did was actually with Alder Lake - the bending of their CPUs under the IHS shields.

And what ***** me even more is that almost no one reported on this issue as an issue, but those few that did went straight into PR mode (Tom's, as I remember) and said "look how you can improve the CPU temps with 3rd party mods to the IHS" - and not a word about the issue, as in criticizing intel for making such a ****** design. Because it's a design flaw, make no mistake about it.

I mean, it's baffling to me how they can turn a flaw into a positive point, somehow.

Now months later we have numerous 3rd party vendors of these after-market IHS shields competing which one fixes the problem better and also improves temps (deba8er/T.Grizlly has the best one for "just" $40).

So you buy an Alder Lake CPU which is "sooo much cheaper and better than Zen3", as they claim, right?

Not only the entire Alder Lake platform costs a lot more than AM4, you also damage your CPU because of intel's inability to design properly and then you lose a least 10 degrees Celsius in a few months when the CPU gets bent under IHS pressure, OR you buy for extra $40 an after market kit to fix this mistake. Cheap right? Pathetic.

Wasn't there just 2-3 weeks ago an article about this issue??

If I remember correctly, Intel threatened to void the warranty if users did something similar (possibly even the same thing)

You understood AFTER you read the article... but a headline shouldn’t mean something different than the article... it’s called click bait...
lol What?
I think you need to read my entire comment again...
I literally excluded myself from someone that was confused by the headline in the first sentence I wrote to you.

Intel said that, yes.
Installation instructions written by Intel is what the warranty covers.

gimmicks for alder lake?

I don't need more than a dualcore Sandy Bridge

Make one @ 3nm and I will come

No gimmicks required!

Extremely Low power draw yet fast enough for everything I need a computer for

If you need dozens of cores, massive power supplies, extreme heat and gimmicks, then keep going where you're going

You're headed in the right direction
