The CPUs ARE delidded, or well, never had a lid in the first place.. they do not have an IHS in laptops. The sink is directly mounted onto the die.

Aw ;d <3

Actually checking this other post from the same customer makes me wonder if they are referring to desktop cpus again since it isn't possible to de-lid a mobile CPU from what little I know about it? Have never seen a mobile CPU with a 'lid' though.
https://rog.asus.com/forum/showthread.php?95874-Does-ASUS-plan-to-release-laptops-with-intel-desktop-CPUs-and-desktop-Nvidia-GPUs

So, I believe xero's earlier reply before it was edited may still apply , but the question may really be will ASUS sell any notebooks with desktop cpus as mentioned in the other post before we can even start discussing if ASUS will sell any notebooks with de-lidded desktop cpus?

From my quick search online though don't believe any manufacturers were selling any notebooks with de-lidded desktop cpus and it was really the resellers making these modifications and selling them to customers.

Well, I may not be correct about some things here, so feel free to correct me or discuss if anybody has other thoughts. thanks.

Oh yeah someone asked about desktop grade CPU's in laptops a while ago. Forgot about that. Well that's going viral now isn't it. ;U

That was my initial train of thought but we already answered that other thread. So I think Darnassus's reply is the most applicable here.

To cover all the bases I guess we could say that ASUS would not physically modify a CPU for a few degrees of cooling. So if it is made with a lid, it would ship with a lid.

the GPUs are also coming delidded in laptops?

As noted, NO big OEM whether it be ASUS, Alienware, Dell or otherwise is going to perform a risky modification on a CPU or GPU or any other chip for "enhanced cooling". Chips are used AS SUPPLIED from the manufacturer.

That would be simply asking for trouble. It isn't going to happen period.

but @Darnassus already has said that the laptop CPUs are coming delided (or better said: already without any IHS)

If Intel or AMD ship the chips with a different die cover then it's still a normal usage of the product. No big company like ASUS, etc is modifying the chips. That's the point.

Apparently Intel did a lousy job bonding their Heat Spreader on certain CPU's which led to a number of people shaving of their IHS to get better heat transfer. Outside of a case like this there is no reason to mod a chip. The chips are designed to transfer their TDP from the die through the IHS to an appropriately sized heat sink. If the heat sink is actually capable of sinking that much energy than no delidding should ever be necessary and it wouldn't be helpful anyhow.

Monroe I'm confused.. what exactly are you trying to ask..?

There's Laptop CPU's that're just the chip with no IHS, so the die is directly pasted to the cooler. Laptops aren't usually expected to be opened and repasted.

There's Desktop CPU's that have the IHS, which spreads the surface area of the CPU, while also allowing better pressure distribution for larger sinks and mounting blocks.

You don't put a Desktop CPU into a Laptop. Too much heat to disperse, more power hungry. No point.

The CPU's we have, the 6700's and above can be overclocked up to 8GHz, so if you want to match a desktop clockrate of 4GHz well, be my guest, though you'll not last very long. ;d

I didn't actually realise you were the one who also posted the "DOES ASUS PLAN TO RELEASE LAPTOPS WITH INTEL DESKTOP CPUS AND DESKTOP NVIDIA GPUS?" thread, and the answer would most likely be no for CPUs not for a long time at least.

The GPU might happen. I believe the ROG Chimera has a Desktop 1080 GPU inside of it.

thanks for replying. just a side question: i think that the GPUs (desktop and mobiles) used in laptops are not delided. so, my questions is: why they are not delided?

Several reasons. For one, the components under the IHS are delicate. When you are making a product for end users to assemble it needs to be somewhat idiot proof. Second, heat sink quality varies. If the IHS does a reasonable job of spreading the heat then it's OK if your heat sink is making sub optimal contact as long as it makes enough to transfer heat. If you put a crappy heat sink directly onto the die it could make poor contact and cranking it down to make good contact could crack the die.

well, the CPU electrical circuitry is also as complicates as the GPU's. so, they are in the same boat, but desktop CPUs are delided.

Again, because they are not installed by end users. They are preinstalled by the hardware vendor and the heat sink is designed to work with the chip being installed. Most customers will never see the naked CPU/GPU unless they are voiding a warranty. For chips that are sold direct to the public and may be used with a variety of coolers they are protected by an IHS.

ok,
if ("chips that are sold direct to the public and may be used with a variety of coolers they are protected by an IHS")
then have u seen smb buying a mobile GPU chip and putting some other cooler beside that one that comes with the laptop? if the mobile CPU comes delided then it makes sense the mobile GPU also to come delided.

The last laptop GPU I had didn't have an IHS either. I'm not sure which GPU you are talking about but it's possible that it uses the same package as a desktop GPU and it was economical to keep them the same.

Anyway, you seem to be greatly overestimating the value of a naked die. The reason you see naked dies in laptops isn't for performance, it's just cheaper. The temperature difference between an IHS and a naked die is pretty minor and the performance potential is relatively small. Everything comes down to cost. Having an IHS protects the manufacturer from RMA claims and encourages people to build systems. Not having an IHS saves money in situations where it isn't as necessary.

Most GPUs now are never manufactured (GTX 600 and beyond, unless rare circumstances) with an IHS, they're all bare to the die and mounted directly onto a sink.

The only good reason a GPU would have an IHS on it is if it's inside of a gaming console.

@xeromist and @Darnassus thank you very much for replying me. i have definitively learned new things with you which i appreciate very much.

Im guessing there is a language barrier at play here.

For laptops you cant delid something that never had a lid in the first place. The cpus and gpus are permanently soldered to the motherboard.

See any heat spreader to remove? Thats because they never existed.
