Teardown of NVIDIA’s Next-Gen RTX 50 Founders Edition: Exploring the Innovative “Double Flow Through” Thermal Solution with Dual Fans and 600W Cooling

NVIDIA has unveiled detailed insights into its innovative cooler for the upcoming RTX 50 Founders Edition, which features a unique “Double Flow Through”design aimed at maximizing thermal performance.

A Closer Look at NVIDIA’s Advanced Cooling Solution for RTX 50 Founders Edition GPUs

Recent hands-on experiences with NVIDIA’s cutting-edge GeForce RTX 5090, the flagship of the Blackwell Gaming GPU lineup, have showcased its compact printed circuit board (PCB). During the comprehensive Editors Day event, NVIDIA elaborated on the enhancements made to its cooling technologies, specifically for the Founders Edition graphics cards.

The latest cooling configuration represents an advancement from previous designs rooted back to the GTX 10 series, which initially employed a blower-style cooler. As the series evolved into the RTX 20 series, NVIDIA introduced dual axial fans in the Founders Edition models, setting a foundation for further innovations.

The RTX 30 and 40 series witnessed substantial increases in cooler dimensions, with the RTX 4090 and 3090 utilizing a robust 3-slot design. However, in a surprising move, NVIDIA has opted for a more streamlined dual-slot layout for the RTX 50 series, ensuring substantial cooling without compromising on compactness.

The cooling system integrates a 3D Vapor Chamber strategically positioned above the compact PCB. This advanced chamber efficiently transfers heat away from not only the GPU itself but also from critical components such as VRAM and power circuitry. This heat is then effectively dispersed throughout five substantial heat pipes connected to three heatsink assemblies featuring an extensive array of aluminum fins.

The design includes two outboard heatsink blocks that interface with the heat pipes, while a central heatsink resides beneath the PCB. This configuration is complemented by dual axial fans, which help facilitate effective airflow through the heatsink stacks.

NVIDIA claims that the RTX 50 Founders Edition’s cooler significantly reduces acoustic noise during operation compared to its predecessors. In quantitative terms, past models such as the RTX 20 series under a two-slot dual-axial configuration reached noise levels of up to 50dBA at around 300W TDP. In stark contrast, the RTX 50’s design allows for a much quieter experience, producing around 30-35 dBA even under loads approaching 600W.

With the launch of the NVIDIA GeForce RTX 50 series just days away, enthusiasts and gamers alike are eager to see how these new Founders Edition coolers perform against previous generations, particularly in terms of thermal efficiency and acoustic levels.
