Seems P53 has plastic chassis, I bought fan stand for my laptops that have metal chassis because that is used as heat sink. With metal you don’t need magically placed fans you just want to cool the surface.
For overpowered CPU that should not be in laptop it won’t help anyway, I had core i9 and best thing to do was to sell it and just swap to core i7 because there was no home made trick to make it better even with metal chassis.

So close to greatness.
I've dabbled in this and the one thing that absolutely has to be included is a seal on the edges between the laptop and the stand like so:
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):
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.

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.

We need way more of this content! Things that were tried and failed. I have spent so many head-scratching hours on problem solution approaches that others likely already tried and failed. In science we only celebrate success. Even then it is typically poorly documented.

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.
I drilled some holes in my Framework laptop's bezel.
It isn't designed to be used with the lid closed which is what I do 99% of the time. After drilling the performance with the lid closed went up 30%, with the lid open up 5%. Removing the bezel with the lid open gives extra 10% vs normal bezel.
The nice thing is these can be swapped easily (magnets) and come in different colors. I used to have 2 until I stopped caring about my laptop looking weird in public.

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.

I got a laptop cpu in a desktop motherboard (a mini PC board). It was cheaper, and performs much better that the same cpu in a laptop. It was a steal. It's like shucking an hdd, an incredible value for the price.

Raising it is the most important part. After that, if you can pop the bottom off while it's running, and swapping out the thermal paste are my go-to.

Amazing they're called 'laptops' when you haven't been able to safely keep a laptop on the top of your lap for decades.
Even slight increases in temperature is enough to do damage to certain parts of a man, and it's really not good for your legs to have this extremely hot air blasted over it continuously.

How feasible would it be for laptop manufacturers to add a slot in a laptop's underside cover to the CPU's heat pipe, and adjust the heat pipe's shape at this location? This would allow a dock to insert its own heat pipe through it, and dissipate the heat with larger fans and/or larger heat sink.

For Macbook Air there was DIY solutions where people added thermal pads to conduct the heat to the aluminium chassis and then use external cooling on that [1]. Since Air just has passive cooling, this gave major boost for long running tasks.
Totally noob question: Couldn't the problem just be that the laptop body not conducting heat so much? I think it'd be worth to try it with a macbook.

Another thing author missed is thermal paste. I got way better cooling in my 2-year old framework by just replacing the dried out paste.

> I picked the locations of the fans and their supports very carefully, and it’s clear that the intakes aren’t blocked.
Just double checking: Did you put the fans in the correct orientation and on the intakes instead of the exits?

Aren't those laptops designed to boost until it hits the max temp ? OP should test performance before and after.

I’ve had some mild success with external piezoelectric coolers. However, the form factor isn’t ideal (weird angle, which led to a lot of returns from other people, so it’s no longer on Amazon)

Otherwise the air will escape to the sides.
