Продал RTX 5090 ради ЧПУ, чтобы собрать ЭТО…

I took a crazy step: I sold my RTX 5090 to buy a CNC milling machine! My first serious project on the new hardware was creating a custom cooling system for a unique and very noisy graphics card—an RTX 4080 32GB. In this issue: Why did I do it? Why I traded my top-end graphics card for a milling machine, and what opportunities does the RTX 4080 32GB open up for local AI generation (compared to the 5090). The path of a CNC newbie: Burned boards, smoking cables, searching for drivers, and tons of broken cutters. An honest account of what a craftsman faces when mastering new hardware. The Magic of Copper: The process of milling a massive copper plate weighing several kilograms and a custom plate for video memory. Result: Reinstalling the board on a gigantic cooling system from the ASUS ROG Strix 4090. Did we manage to achieve silence, and what mistakes did I make when designing the heatsink? This video isn't just a review, but a story about how, through pain, time, and expense, a true custom build is born.
