Why Apple didn't put a heatpipe on 2018 Macbook air?

Ha, I was wondering the same thing!
I would imagine some people will figure it out themselves, but I do not think there will be a third-party solution.
You will not need it anyway. Mac Air is completely handcuffed with its' voltages by Apple. Max from youtube liquid cooled it and there was no difference, except temperatures. CPU was cool at 50C degrees, but didn't want to go above 1.8 Ghz.
Also people from this forum have posted results with max fan on geekbench5, and it was much better.
So just turn on your fans at full blast manually, and that will be enough. No point in making it much more complicated, as it won't affect performance.
I would argue it was designed intentionally this way for product segmentation/differentiation.
In his video, there was an increase in performance by about 16% in Cinebench R20 with liquid cooling. You are right in that the limits remain, but the cooling prevented the CPU temperature from hitting a thermal limit and instead, let the CPU continue to perform until it hit the power limit or the voltage limit.

This isn't possible because T2 chip (which holds the EFI, Intel firmware, and is locked down like an iPhone) pushes the firmware via eSPI bus. You would need a jailbreak method just like iPhone do.

Agreed! But also I have seen participants from this forum sharing their gb5 scores, with full blast fan manually activated(normal fan 3295/max fan 3900). So there shouldn't be much of a difference between liquid cooling and max fan for new Air. Because mac os on new Air never hits 100% fan rpm. So at least we could set it manually to 100% in order to increase power without further inventions.
They didnt put an heatpipe bec Apple knew that from this 10th November, Tuesday the macbook air will go arm...so i guess we will have the same internals on this, same battery, same single vent just for airflow but with arm chip that doesnt need a heat pipe so they could save a lot of money by selling for once this Intel version,and from November , i guess, the arm version
The Air devices are not Pro devices. Providing a proper heating solution would blur the performance capabilities. Apple needs the Air to be a cheaper/inferior device.
