MSI shows the thermal design for future RTX 40 series graphics cards
At this year’s Computex 2023, MSI unveiled an impressive assortment of products. Among them, the pioneering RTX 4060 graphics card, entitled “GeForce RTX 4060 VENTUS 2X BLACK 8G OC,” took center stage, along with a GeForce RTX 4090 graphics card, featuring an avant-garde cooling module. This tri-fan design, with a girth reaching 4.2 slots, is rumored to be utilized in future GeForce RTX 40 series graphics cards.
According to Wccftech, the cooling solution exhibited by MSI is dimensionally superior to the one employed in the current RTX 4090 SUPRIM X graphics card, presumably designed to accommodate the yet-to-be-released RTX 4090 Ti. MSI proclaimed the utilization of a novel dynamic bi-metal cooling fin design, sandwiching a copper fin between two aluminum ones, thereby enhancing heat dissipation efficiency.
MSI also showcased other pioneering solutions in graphics card cooling, encompassing DynaVC and FusionChill.
DynaVC is an air-cooled solution, incorporating a 3D equi-thermal plate. Contrary to traditional equi-thermal plates, which necessitate planar contact with the rest of the heatsink, MSI’s 3D approach allows for superior contact with the GPU. This eliminates the issues of soldering heat pipes to equi-thermal plates, amplifies thermal conductivity, and disseminates heat to the stacked aluminum fin heatsink.
FusionChill represents an integrated all-in-one water cooling solution, quite akin to the design deployed in Acer’s showcased Predator series flagship NVIDIA graphics card. Compared to the latter, MSI’s approach appears less elegant, still requiring fluid pipe connections, albeit future design improvements are forthcoming. According to MSI, this design surpasses standard 240mm specification heatsinks by 10% and offers an additional 15% of cooling fluid.
