MSI Adopts Diamond-Laced Cooling, Safe 16-Pin & Resettable Fuses to Tame NVIDIA’s Next-Gen RTX GPUs

MSI has unveiled its next-generation cooling solution and power design that will be used on future NVIDIA RTX GPUs.

MSI Has Some Wicked Cooling & Power Innovations Ready For Next-Gen NVIDIA RTX GPUs

Although this year isn't bringing any major GPU launch for gamers, MSI decided to showcase some of its own innovations that it might incorporate into future GPUs, mainly NVIDIA's RTX series.

MSI is showcasing three key design features that cover the cooling, the power delivery, and the PCB. Let's start with the cooling solutions.

First up, MSI is building an advanced thermal architecture that features new fans, new heatsink design, new heat pipe design, new thermal pads, and new baseplates. The following are the main technologies that MSI is working on to power its next-generation thermal solution:

• Ultra-Thin Metal Fan Blades
• Advanced Spiral-Groove Heat Pipes
• Diamond-Composite Thermal Pad
• Diamond-Copper Composite Baseplate

For the fans, MSI is opting for an ultra-thin metal fan blade design, which features the same 7-blade design, but comes in an all-metal design that delivers up to 40% better airflow through the use of a high-rigidity metal structure that is packed in an ultra-thin 0.8mm design. Some of the highlights of this new fan include:

• High-Rigidity Metal Structure: Resists blade deformation at high speeds for stable airflow.
• 0.8mm Ultra-Thin Design: Increases effective airflow area by reducing blade thickness.
• Reduced Airflow Resistance: Wider airflow paths to improve efficiency at high-speed operation.

Now let's move on to the actual heatsink design. The first of these innovations is the advanced spiral-groove heat pipes, which increase contact area to improve heat pipe efficiency versus a conventional heat pipe.

The new solution also comes with a diamond-composite thermal pad for the memory modules, which helps improve thermal dissipation, & finally, we have a Diamond Copper composite baseplate which features a Diamond-Copper layer stacked between two Copper layers within the baseplate that creates a high-conductivity path from GPU to heatsink.

All of these technologies come together in the form of a fully integrated cooling module, and one of the first designs that MSI has showcased is a next-gen Gaming Trio graphics card. It was showcased on an existing RTX 5090 32 GB GPU, but this is just a prototype for now. The final version will debut with NVIDIA's next-gen GPUs.

Safeguard Now Exclusively on MSI GPUs

Another feature that MSI is integrating within its high-end GPUs is the same Safeguard tech, which has already made its debut on the MSI MPG PSU lineup.

The same features and same level of protection/control through software/hardware will now be offered directly from the 16-pin connector on the graphics card, so you will no longer require a compatible PSU for this feature to work. MSI is currently working towards validating this technology with more PSUs & is expected to give it a new name.

Reuse The eFuse

Last but not least is MSI using server-grade and reusable fuses on its future GPUs called eFuse. The use of these new fuses helps shield the GPU from electrical damage with an internal gate-based reset mechanism. The best part is that these fuses are resettable and reusable, offering fast short-circuit response of around 200ns, and offer long-term reliability.

MSI has showcased this design on its RTX 5090 SUPRIM (Safeguard), but once again, these technologies will debut on future graphics cards. So it looks like MSI is working hard on some innovative features for cooler and safer GPU operation.
