sera q tem backplate de plastico igual as ventus 2x?
Eu sei que a Trio X o backplate dizem ser de GRAFENO.
Agora as Ventus 3x precisa dar uma pesquisada melhor nos reviews.
A Ventus 2 tá no site apenas como "placa posterior de reforço - com acabamento escovado", ou seja nem de metal é.
A Ventus 3x e Gaming X trio constam como "placa posterior de grafeno". Certamente não é de grafeno porque 1 grama de grafeno custa de 100 a 300 dólares (isso mesmo). Deve ser alguma camada nanométrica, ou algumas partículas só espalhadas pelo plástico. Pode ser que isso já seja o suficiente pra uma boa condução térmica.
Mas a fragilidade já é constatada, talvez alumínio seja melhor mesmo já que é um ótimo condutor tb e bem mais resistente. Fotos de algumas 3080 recebidas com o backplate quebrado por usuários do reddit:
EDIT: achei um review mostrando um pouco do backplate. Resumindo - pelo teste deles é ABS com grafite, e conduz menos que alumínio (além de ter uma resistência mecânica bem menor). Só redução de custo mesmo:
"This isn't any other backplate, MSI markets this as a "graphene backplate" on its website, "A lightweight composite backplate" that "reinforces the length of the graphics card while providing thermal conduction properties." Before we had our hands on this card, we were frankly taken aback by this claim. Graphene remains an exotic and expensive new material. The card even felt different to the touch. It's only when we took the card apart that we noticed that the other side of this back-plate had many shapes and markings resembling normal ABS plastic backplates. So we took a sharp object and started scratching its surface.
There. The graphene composite sitting under a layer of plastic paint. I tested the electrical resistance, which is an excellent indicator of whether something is plastic or graphene/graphite. The paint is non-conductive, but the scratched part conducts electricity. I further tested heat transfer with a heat gun—it heats up slightly faster than a piece of plastic, but not as fast as metal, which is another indication that the material is not graphene. It seem to be graphite mixed with plastic, which is an industry standard method to construct carbon parts. "
The GeForce RTX 3080 Gaming X Trio is MSI's flagship RTX 3080. It comes with a large overclock out of the box, and the cooler is massive. This is the fastest RTX 3080 we've tested so far, and it's the quietest as well. Wow, and that with a classic triple-fan design that doesn't use any fancy...
