Has Samsung changed the cooling system of its Galaxy Note 20?

The teardown specialists from the iFixit site tore Samsung’s Galaxy Note 20 and Note 20 Ultra to pieces. During the operation, they noticed the presence of a graphite pad to evacuate the heat emitted by the processor.

This is rather surprising since Samsung used a copper steam chamber for its previous models.

We can then assume that this new process only concerns models equipped with a Snapdragon 865 processor (Asia and United States). But testers at JerryRigEverything reported that their model, with Exynos 990 processor, also used a graphite pad to dissipate heat. This hypothesis therefore falls apart. Even more surprisingly, a teardown video posted on YouTube reveals a copper vapor chamber in a Note 20 Ultra.

The mystery remains unsolved. Did Samsung initially plan a steam chamber for cooling the Note 20, then change its strategy? Is it a supplier problem and the two processes would coexist? The Korean manufacturer has not yet given an official explanation.

Finally, would graphite be less efficient than copper in dissipating heat? Android Authority and SamMobile testers mention that the Note 20 Ultra heats up a lot. As far as we are concerned, we did not notice any excessive heat on our test model, the test of which will be published shortly.
