Since i'll add here's lenovo's. While it does the same 3rd fan over the GPU, Lenovo instead Covered the SSD and ram with a giant heatsink. As for airflow differences:

Where did you get this picture from?

Highest 5090m score OOTB it seems like. Advertised as having 275w Crossload, 160w cpu sustained load, with an 1100 nits oled screen with 0.08ms peak response time. With aida 64 FPU and furmark, crossload seems to be slightly higher. Going up to 280w. And this is without liquid metal at all. Yeah lenovo removed liquid metal for this model and uses ptm for both CPU. For a non LM 16 inch laptop that's kinda amazing. 275HX just destroys the 14900hx especially with less power. Should allow for cooler loads and better temps in games, And possibly increased performance in CPU bound games due to no longer being power starved. Screen test results. The legion cooling system is different from last years. 3 fans. Large VC for CPU and GPU with secondary heatsink for SSD and RAM. 3rd fan blows air into the gpu. putty is used instead of pads for vram. 2 of the remaining vram spots has pads that uses the 2nd heatsink to cool it. The CPU side is still nickelplated and has a foam pad even with lack of liquid metal. So you can still apply LM if you wanted to. This seems to be a first I think. Having a laptop "liquid metal ready" Secondary heatsink that cools SSD, ram, and some other stuff. it also contains the 3rd fan.

It's been confirmed how it looks like for the cooling https://news.ycombinator.com/item?id=35286544#35289558

Thing is laptops don't really have a certification standard with the only exception being amd advantage which is for all amd gaming laptops and Intel evo which is for Intel ultrabooks. At least it's not as compared to someone's so called "standard" i.e If anyone thought this works I wonder what they are smoking. Although this post was from the same person that wanted a bga socket with interposed even though I don't think that's the best long term solution for bga connections.

There was actually a reason why for that. It reaches its max clocks faster than it can use the wattage. Remember that computerbase.de image I shared?

This looks interesting. https://twitter.com/JarrodsTech/status/1628922420898992129?s=20

I don't remember a 16 inch laptop that fits a 608mm+ die and 384 bit bus. There was only 1 laptop that did and it had to make so much sacrifices. That was the studiobook one. Even so, look at this thing.

Unfortunately it's a pipe dream due to die size. Its double of ad 103's. Mobo's would have to ditch ton of things to fit that along with the cpu. And MXM gpus rn are small. And horizontal space is a premium. 99% 4090 would only go into workstations. And even so, the quadro A series is for that.

Basically the 4070 and 4060 are not wattage constrained. but frequency constrained.

"With the RTX 4070 laptop GPU, this is 2,400 MHz, which are in 11 of the 14 games with an average consumption of well below 115 watts. With the RTX 4060 laptop GPU it is 2.610/2.625 MHz – in 10 of 14 games this clock is already reached at an average of less than 115 watts. This behavior is fundamentally different from that of the two larger GPUs, which operated at over 150 watts in each game in the test, because they were able to convert the additional electrical budget available via Dynamic Boost into even higher clock rates. The maximum possible clock (2.355 MHz for the 4090 and 2.520 MHz for the 4080) was reached only in Far Cry 6. So the clock was almost never the limit, but with the smaller variants this is the rule."

4060 mobile has been tested.

So someone revealed that test mobo's for mobile cpus use interposers. Which are basically socketable bga. same for the chipset. Before some goes "WHY IS THIS NOT IN LAPTOPS?!" It's because these type of sockets are very expensive. like 1k usd+ expensive. Not only that. Interposers can wear. They are not really made for long term use just for testing.

Thats basically the concept of the asus flow series. Though for thr desktop chip thing. They would have to be modified anyway to support the certain laptop technologies. Including things like optimus. Desktop gpus don't really support that in their drivers.

is this for all with nvidia mobile GPUs or no.
