Smartphone and electronics giant Samsung just launched its latest flagship smartphone, the Samsung Galaxy Note 9 last month. With the new smartphone that packed the latest processor and a larger battery, the company also introduced a new Water Carbon cooling system to ensure that the device remains cools in the most demanding of the situations. The reason to introduce this new cooling system was to ensure that the device does not thermal throttle in demanding situations such as heavy games such as PUBG Mobile or Fortnite. However, the company did not dive deep into the cooling system to share how it really works. Also Read - Samsung Galaxy Z Fold3, Galaxy Z Flip3 launch on August 27? New report suggests

In addition, Samsung added that the heat sink in the Note 9 was the largest ever that the company had used in any of their smartphones. Considering that it was the largest heat sink in a Samsung device and there was not much known about how it really worked, a number of users started tearing up their Note 9 devices to verify the claims by Samsung while trying to figure out how the system worked. It looks like Samsung was looking at the teardowns on the internet and wanted to clear the air. Also Read - Galaxy S21 FE flaunts itself again on benchmark, reveals RAM for high-end Samsung model

What appears to be a response to all the teardowns and analysis, the company has published a new post with notes from Tech lab highlighting the difference in the components that make the new, largest heat sink in the Note 9. The report pointed out that water cooling initially made its debut in the Galaxy S7 but the company made improvements both in the efficiency of cooling as well as the capacity of the water cooling when it came to the Galaxy Note 9.

The post pointed out that the reason to improve the water cooling was to prevent thermal throttling what would lead to a loss in performance if and when the internals of the device would get heated. With the S7 the company used a porous thermal spreader that was filled with water to absorb the heat from the processor and then take it away spreading it in a wider area. For this, the water would turn to steam when it would absorb the heat from the processor and then turn into the water once it was dissipated.

Samsung added that in the initial system, it used two Thermal Interface Materials (TIM), one with highly conductive carbon fiber to transfer the heat away. To improve the system, the company opted to add a layer of copper between the two TIMs which made it possible for both the materials to transfer more amount of heat. The company also made a wider thermal spreading pipe with 350mm when compared to the 95mm in the S9. As part of the report, the company claims that the Note 9 has 3 times more heat absorption and 3.5 times more thermally conductive than the Note 8.
