So you say that you didn't notice the laptop temperature getting any lower, but this isn't too surprising to me, since this thing is going to be highly thermally limited.
I suspect that your setup is doing something, but the thing it's doing is allowing your laptop to sustain a certain performance level for longer. So what I would look at is some performance metric like e.g. peakflops() in a loop, or a video game FPS counter, and compare with and without the external fans.
BoppreH 1 days ago [-]
The laptop fans are also targeting a set (maximum) temperature. If you provide external cooling, the internal fans will simply work less and the temperature will remain stable. So check the RPM of the internal fans too.

Another factor is the CPU behaviour. The CPU involved in the article is intel, but IIRC for AMD Zen4 (at least for desktop) they made them boost up to a relatively high but well within spec temperature, rather than leaving performance on the table that only tweakers will see. The better your cooling capability the more you'll get but it caused a few people to freak out a little. Aspects like that are why I reserve the noisy part of my fan curve for when temperatures are going beyond normal.

Even Intel does the same thing. Every modern CPU does this.

Exactly. If you increase the capacity of a bus in a highly crowded area, the bus will still have 100% occupancy, but that doesn't mean it didn't help. The throughput increased.

Much like adding an extra lane to a highway, more people will use the highway and you'll be back to the same crawl. But technically there's more flow/capacity.

Curious that you are being downvoted for the car analogy when the bus analogy you're replying to is functionally identical.
garretraziel 1 days ago [-]
Because it’s a slightly different argument. “More people will use the highway” is not really applicable here. The bus analogy also didn’t meant “more people will take a bus”, just that if you have bus route where 20 people on each bus stop need to wait for the next bus, if you increase capacity of buses by 10, then only 10 people will be waiting on bus stops, but you will still have 100% bus utilization.
In other words, with added lane on highways, it’s sociological mechanism, which is slightly less precise analogy.
wongarsu 24 hours ago [-]
If you run the same bus route and frequency, one day with buses that fit 50 people and have 100% utilization, and the next day with buses that fit 100 people and have 100% utilization, you transported twice as many people on the second day as on the first day
This implies that on the first day a lot of people either didn't make their trip because there was no space, or took a different mode of transport. Presumably mostly the latter. With the highway example the same is true, just that it will be mostly people not making the trip at all before the capacity improvement because they were unwilling to make the higher time commitment

The little tiny fans in the laptop will typically be able to move a small amount of air with a large pressure. The fans you have used here externally will be able to move a large amount of air with a low pressure, but since you're trying to cram that air through a small space, they will actually be able to move a minuscule amount of air with that same low pressure. That's probably mostly why you aren't seeing much improvement.
I'd say that you have two options.
The first is to try to use external fans to force more air through the laptop than the internal fans manage. You'll need high pressure (probably centrifugal rather than radial) fans to achieve this. They'll be noisy.
The alternative, which can use quieter low-pressure fans like the ones you have, is to just ensure that all the air going into the air intakes on the laptop is as cold as possible. That is, make sure the air going in hasn't just come out. And make sure there isn't any more restriction on air flow than the minimum possible, which the raised gap under the laptop will achieve. You basically just want to direct fresh cold air from far away from the laptop towards the air intakes, and pull the air emerging from the air outlets as far away from the laptop as possible. A horizontal breeze flowing across the bottom of the laptop is probably one of the best ways to achieve this.

As is the conclusion of the article, one of the easiest things to do is simply raise the laptop more off the surface so there's less impediment to airflow.
I was recommended these by a friend and the ability to easily do that anywhere (and as a nice side-effect get a lovely angle to the keyboard) but still be able to pop the laptop in a backpack easily is amazing. They have been put on every laptop my wife and I have owned for the last 6 years.
happymellon 1 hours ago [-]
Similar concept, but I have this as it folds into a smaller size for backpacks.
For my home project I used foam tape, but any seal will do.
Regarding cooling I wholeheartedly recommend one Framework 16 owner's journey in making his device maintain 80°C with the CPU going full throttle (aside from other mods):
Don't you want it to do that? The air goes upwards, hits the laptop surface, and travels outwards carrying the heat?
If it's sealed, I imagine you would get a very turbulent situation, possibly far noisier, but also one where I can't intuitively picture the airflow and expected cooling flow. I should note I am very, very far from an expert here ;)

There's a lot going on here, but the gist is that even a magnesium alloy laptop chassis is a rather poor conductor of heat (for a metal) and you really have to push that air through the machine to get it out.

So I had a similar problem and what actually worked pretty well was an external vacuum fan [1]. I tested it before by just using an inflator I had to pull a vacuum and I watched the CPU temp drop so I knew this was valid.
Compact electronics rarely have vents "close" to the things that get hot - it's been heat pipes for a long time already; and that system is fixed and "scaled" for the included fan(s)... Not much anyone can do in practice without taking the laptop apart - at which point you'd be better off buying a (mini) PC in the first place.
Also: thermals in general are vastly more complex and tricky than our intuition tends to tell us (with the article being a great example of it!).
schobi 1 days ago [-]
Well - the challenge is with the right type of fans.
I like the idea of a pump curve for a garden water pump. If you pump water without any back pressure (not even a hose connected), the pump will give a certain volume per time that is can move. If you connect a hose and pump upwards, you will reach a max pressure / max height at which no water will flow any more. Both cases are useless, but this is what the manufacturer prints on the box. Your sweet spot is in between. If you pay enough, you will get a datasheet with the pump curve in between these two points.
For simple and cheap PC fans, you are at most given the number of air volume without back pressure. I've not come across a cheap fan that gives a defined backpressure of even a curve.
For your application you would need a fan that can push air through a restriction.
I had success with high rpm server fans. They create pressure, consume 20W of power or more and also make a lot of noise. But in this case - this is not a solution
schiffern 22 hours ago [-]
Check out Cybenetics. They publish tested PQ curves even for cheap fans like the Arctic P14.
Probably a monster chip like that has way more headroom than you expect, and can max out the extra cooling you’re giving it as well. If the goal is to avoid the 90C blast, maybe enabling thermal throttling plus using the custom cooling setup will give you (much?) less of a drop in performance than throttling with stock cooling?
edding4500 1 days ago [-]
Just a note: some laptop fans are not solely controlled by CPU or GPU temperature, but also by power consumption. This may explain why your laptops internal fans are still spinning up under load, even though the external fans do all the work already.

You'd be surprised by how much of a difference just cleaning the fans and applying new TIM will do. Preferably using a quality phase change TIM like those from Honeywell or Laird will work very well on devices like this.
I actually replaced the stock Liquid Metal on my ASUS Zephyrus with some Laird PCM and hot spot temps actually evened out towards the lower end and the low/high/average temps were the same after around a week or two of thermal cycling.

If you have some extra $$$ (on the order of $250), you could start buying TE coolers. When I was an undergrad long ago, in my internship job we were cooling a focal plane on a satellite using some TE coolers [electracooldotcom] from the precursor of this company.
OR maybe try immersing the unit in ampcool or bitcool [engineeredfluidsdotcom] (again around $250) and use a recirculating pump from a fish tank and some clever piping into the hot parts inside the case of the laptop then out over a decorative waterfall to bleed off the transferred heat from the PC into the environment

Thermoelectric coolers are an interesting technology, but have fairly poor efficiency. Plus, you still need somewhere for the heat to go (which probably still means heatsink + fans).

FTA: “In the end, I’m not really sure we can just put dissimilar fans in series. If you put a fan that can pump (say) 200 cubic feet per minute (CFM) in series with a fan that can only pump 100 CFM, what is the resulting output? Probably not 300 CFM.”
- "n" fans in series will increase pressure "n" times at a given flow rate, with no additional free delivery flow. Fans in series can be useful in high resistance systems.
- "n" fans in parallel will increase flow "n" times at a given pressure level, with no additional shutoff pressure generated. Fans in parallel can be useful in low resistance systems.”
rickdeckard 1 days ago [-]
I'm not surprised that this doesn't change the CPU temp.
The important heat-exchange from the CPU is usually managed by a heatsink and a radial fan, with the grille of the casing designed as fan inlet/outlet.
Blowing/sucking additional air at the inlets doesn't affect the cooling surface of the heatsink, it just blows at the radial fan.
This may make sense if there's a weakness of the radial fan (that heat is building up at the heatsink which the original fan cannot remove).
But it's much more likely that the heat is not distributed well away from the CPU, either to the heatsink (thermal paste) or by the heatsink (weak heatsink design/material).
I'd look into ways to replace the radial fan or the thermal paste

I also had to buy SODIMM DDR5 RAM modules (just before prices skyrocketed, I got 64 GB for $180), a 2 TB Samsung NVMe SSD, and an RTX 5060. The CPU comes with an integrated GPU, but I disabled it to get better cooling.
I also wanted to replace the CPU cooler with a Noctua one, but the GPU sits too close to the CPU. Maybe someday I'll adapt a liquid-cooling radiator, but that would require 3D printing a custom adapter and making multiple trips to a 3D printing shop for trial and error. That's too much hassle.

You can use a thermal strap to transfer heat through the laptop hinges and in to the top screen area. This kind of technique is used in aerospace and other industrial applications to transfer heat from unusual places.
But trying to do this on a laptop introduce thermal issues for the screen. LCD/OLEDs are rather heat sensitive. OLEDs especially do require good heat sinking for the performance and display life.

Your sweet spot is in between. If you pay enough, you will get a datasheet with the pump curve in between these two points.
For simple and cheap PC fans, you are at most given the number of air volume without back pressure. I've not come across a cheap fan that gives a defined backpressure of even a curve.
For your application you would need a fan that can push air through a restriction.
