AMD's Upcoming Zen 4 CPU Delidded by Overclocker

It appears that AMD's Zen 4 based CPUs are making their ways into the hands of overclockers and so far at least one has already been delidded. Although we only get to see the IHS itself, it's clearly very thick compared to what we've seen in the past, although it appears to be fairly straightforward to remove, if it wasn't for the fact that the two CCD's and the IOD are soldered to it. Unlike current CPUs, which have a solid seal, the Zen 4 CPUs appear to only have the IHS glued to the CPU packaging in a few spots.

Judging by the looks of the area where the CCDs and the IOD attach to the IHS, this looks like a destructive delidding, although it could just be leftovers from the soldering material. The IHS has clearly been coated with some materials for a good solder interface as well, but this is nothing new, as we've seen this on delidded, soldered CPUs in the past. The person who shared this picture should most likely not have done so and as such, we won't be posting a link to the source.

I'm so curious about cooling on these now and how effective it will be

Solid State BrainSuch thick IHS possibly mitigates bending issues, which have always existed to some extent on Intel anyway (just got worse with Alder Lake).
Instead it will bend the motherboard :P

Risky being a beta tester for these though. After all the jibes at intels ADL wonder how many hypocrites will buy these now.

Have these been proven to bend mobos? Because I call FUD the things you say.

The jibes were earned by bendy socket's.

It's not yet the case that AMD'S new socket has been proven to have that issue.

So how then could anyone be a hypocrite?!.

Do you read what you post because dammmnnnnnn time and again it's some defamatory bullshit that shows a clear bias that also instigates a us v them war of words you then later moan about.

230w PPT, thick ihs, smaller process.. these are gonna be hot. I already know how hard it is to cool 230w PPT.

TheDeeGeeLooks like LM disaster when it spills underneat, so many gaps ^^
There's no need to go "Direct die" cooling on Zen CPU's. Most of them are soldered and they do quite a good job in terms of heat transfer. The max we've seen is barely 4 degrees cooler once you remove the IHS.

Not sure if thats worth breaking your warranty.

The 230W PPT is only at higher end models.

2 chips on the edge. Gonna have to make sure cooler and thermal paste get right to the edge or a bit further

The beta test jibes were not just about the socket at all. Just the usual TPU anti Intel bullshit.

And you are the ONLY one saying time and again it's some defamatory bullshit strange eh I think you just like to find any excuse to shit stir with me when you could just ignore me and not cause trouble. Do i do the same to you even if you annoy the fuck out of me? no i just leave you alone. Maybe you should try doing the same.

I read loads of comments saying it's bad to buy first gen of new board/CPU as was the case with ADL, but I guess it's different when it's AMD eh. So many double standards on TPU now.

Maybe I should just switch to AMD and join in the Intel flaming posts, can't be called biased then can I.

No one was bashing Intel, your precious was kept out the convo in this AMD based thread.

And I agree, don't buy generation one, ever :p.

Maybe you should chill out, and work on your banter, if that's what you intended.

And stop taking everything so personally.

It's probably thicker due to be soldered so while it will absorb plenty of heat it can transfer it more effectively to another source at the same time. That only helps if the other source can then dissipate the heat effectively enough, but that's expected given it'll either be bundled with a appropriate cooler or TDP ratings will dictate what type of minimum level of cooling to pair with it. I really doubt it's that thick simply due to bending concerns.

Given the overall thickness is it possible that it's a vapor chamber designed IHS soldered to the die between itself and cooling options mounted to it!!?

I take things personally when it is aimed at me, which your replys to my comments quite often are.

And it's not my precious, it's just a CPU. AMD users on here are far more touchy about their precious than me.


Let's just see how zen4 and AM5 pan out. Intel has been using these socket types for a long let's see how AM5 goes for AMD.

Not a great fan of the IHS design but hopefully it'll be ok.

Just stick to a thermal grizzly pad on the IHS or don't fret over the the paste is gonna suck to clean part which paste in my experience has always been a hassle to clean anyway. If Zen 4 one architecture to rule them all "my precious 16c" :roll: Lisa Su's sweet 16 edition... :laugh: I certainly hope it's good for the meme's alone.

I wonder why they don't make IHS's with built-in water blocks? You know, just hook up the hoses and let it rip!

I for one will gladly pay for such option. With power reaching 250W every degree helps. I'd estimate at least 5-6C lower temps with such solution, which should do miracles here.

With an IHS that thick, and non-centered Chiplets, I'm wondering if a composite IHS would be 'in the cards'. Either 2 copper sheets sandwiching a sheet of pyrolytic graphite, or 2 copper sheets CVD'd with Graphene and pressed together. Copper conducts heat well, but evenly. 2D and semi-2D carbon allotropes conduct heat across their planar axis considerably better than copper or silver does.

Unlike a decade or 2 ago, (when tech enthusiasts first started 'playing with' allotropic carbons' thermal properties) pyrolytic graphite and/or graphene are common materials nowadays in microelectronics cooling.

Separate thought: Is there any technical reason preventing the end-user from sealing the IHS to the CPU-package's PCB with black Silicone II or nail polish? (Can heated air trapped under the IHS 'dislodge' or damage anything, if not allowed free exchange with atmosphere?)

Well AMD do use LGA on server so it's not new, they should be fine.

I argue against your opinion, btw, it's your opinion, not you that's debatable.
