  • The strangest thing about these phones so far is, of all things, what lies underneath the motherboards.

  • To soak up all the heat from each phone's octo-core processor, we expect to find a sprawling copper vapor chamber here—the kind Samsung was always quick to brag about in previous Galaxy Phones. But instead, we find a multi-layered graphite thermal pad.

  • Stranger still, it seems some other Note 20 phones do have copper heat pipes—but not our US-spec model. Does the Exynos SoC on international models require different cooling hardware than our phones, with their Snapdragon processors?

  • Our friend Zack, of JerryRigEverything fame, tells us his South Korea model also has graphite. Stay tuned for more details on that.

  • Our next thought was, maybe this comes down to heat-prone 5G mmWave hardware, which not all Notes have—but that doesn't line up either. Is it some kind of A/B test on new cooling hardware? There must be some logic here, but we can't figure it out. Let us know if you have ideas.

  • Update: We gathered some additional intel on the different cooling systems and some inside dirt on Samsung's design process. Read all about it!

  • Speaking of mmWave modules—both our phones have them, but only two each. In contrast, the Note10+ 5G and S20 Ultra got three. Has the hardware improved such that only two are needed, or is something else going on?

Al momento, la cosa più strana trovata in questi telefoni è la roba che c'è sotto le schede madri.

Per assorbire tutto il calore prodotto dal processore octa-core, ci aspettavamo di trovare una vapor chamber in rame, del tipo che Samsung ha messo in precedenti telefoni Galaxy. Invece di questo, abbiamo trovato un pad termico in grafite multistrato.

Ancora più strano, sembra che alcuni altri telefoni Note20 abbiano davvero tubi di calore in rame, ma non è così per il nostro modello per il mercato USA. Forse che il SoC Exynos dei modelli internazionali richiede un hardware di raffreddamento diverso dei nostri telefoni, dotati di processori Snapdragon?

Può darsi di no, perché il nostro amico Zack, noto come JerryRigEverything, ci racconta che anche il suo modello internazionale ha il dissipatore in grafite. Restate in contatto per saperne di più nel prossimo futuro.

Il nostro pensiero successivo è stato: forse deriva dal carico termico dell'hardware 5G, che non tutti i Note hanno? Ma non ci sembra quadri lo stesso. Forse un tipo di esperimento controllato sul nuovo hardware di raffreddamento? Ci deve essere qualche logica alla base, ma non riusciamo a immaginarla. Se avete qualche idea, fatecelo sapere.

Parlando di moduli per onde millimetriche, entrambi i nostri telefoni ce li hanno, ma soltanto due a testa. Per confronto, il Note10+ 5G e l'S20 Ultra ne hanno tre. Forse il software è migliorato al punto che ne bastano due, oppure c'è sotto qualcos'altro?
