This was for science, as it allows us to see inside the vapor chamber, the heatpipes, and the cooling structure to understand how coolers are internally formed. We'll have a review of the RTX 4090 Founders Edition soon, but for now, we're starting with a cross-section and engineering-heavy video to learn about cooler design.
