acer aspire 7 Heat pipe leak issue possible that it might got leaked.

Hello acer,

I have been using acer aspire 7 (ryzen 5 5500u + gtx 1650) for a year and my experience with it was awesome, but after the month of march 2023 I started observing heating issues as the games which were around with 70 C° - 80 C° cpu temp now they were touching 90 C° above (software used for stats is msi afterburner) . I'm always very gentle with my electronics so I got it cleaned up and applied new thermal paste as soon as I found the problem. But the problem was still not fixed, fans are working correctly .

I observed a corrosion mark on the heat pipe as I knew heat pipes contain some sort of cooling liquid it may have been possible that it might got leaked . I have attached a picture of my laptop's heat pipe and it's corrosion please confirm if the problem is because of heat pipe and it's solution.

Firstly, the thermal module of your laptop does NOT contain any liquid(s)! Otherwise your laptop would have stopped operating long before you would have noticed that stain on the heatsink if any liquid would have leaked onto the chips that are underneath the thermal module.

Heat pipes are usually made of copper or aluminum and the wick structure inside is either grooved, a wire mesh (wrapped screen), sintered, or fiber. Of these, sintered pipes are the most expensive to manufacture but offer excellent heat conduction from the wick to the wall and vice-versa.

This is the theory of how your laptops components are cooled, so learn and appropriately remedy these factors like clean the fans, replace the cpu/gpu paste and make sure that your cooling fans operate 100% and dissipate the heat properly.

As you have shown in the image, we can see multiple copper heat pipes that travel away from the CPU and GPU towards the fans. If you look closely, you can see that these copper pipes actually lead away from a copper block that is present on both the processors. This copper block, or thermal block if you will, makes contact with the actual CPU/GPU via a thermal paste. So the heat transfer occurs as CPU/GPU > Paste > Block > Heat Pipes. The idea is to transfer the heat from the chip as fast as possible to the thermal block for efficient dissipation. Why is this important?

Without going into too much detail, each chip is rated to dissipate a certain amount of heat when operated at its rated TDP. While there is no consensus among chip makers as to how the TDP is calculated, OEMs do their own testing to see how far this TDP can be pushed within a given chassis size. Now, if the heat is not drawn away from the chip in a timely manner, the increased heat envelope around the chip forces it to operate at a lower frequency to prevent damage, thus affecting performance. So that is what is happening to your laptop and it needs inspecting of all its thermal modules that they operate perfectly.
