How to increase the efficiency of a laptop heatpipe?
If I turn the laptop over and open the lid, the temperature drops sharply. Due to what?
Drilled a hole under the cooler. Efficiency has dropped. Hot air goes up and cold air blows out through the holes to the bottom.
If you drill holes in the laptop cover opposite the heat pipe, will the cooling improve? Or hot air will not go down?
If you attach a copper wire to a heat pipe, then only a couple of centimeters of the wire gets very hot. Then the wire is a little warm. Heat is not transferred further. It was not possible to remove the heat with a wire.
If a heat pipe or heatsink is coated with thermal paste, will the cooling improve?

Answer 1

No way. Replace with a new one. Possible depressurization of the current one.
Close the hole, there is an extra air leak
Do not make new holes, it will not get better
No, it will not improve
Show the laptop and your alterations. Show the temperature under load
If the laptop is on the table, then the enlarged legs to the bottom help corny. What would the clearance be from 3mm

Answer 2

only a couple of centimeters get very hot. Next - a little warm.

This is a sign of depressurization - heat transfer does not take place in a regular way (not through the evaporation of the coolant, which, apparently, has disappeared long ago), but through copper. It cannot be repaired, only a replacement (although there is info about home-made TTs on the Web). A serviceable CT should be equally heated along its entire length, the temperature gradient is imperceptible to the touch.
Soldering wire, thermal paste outside the CT - useless. Additional holes in the hull are sometimes useful.
