MSI makes Nvidia GPUs cooler and safer with thin fans and reusable eFuse

MSI showed several techniques at Computex that should make future GPUs from Nvidia safer and provide better cooling. The techniques are intended for next-generation graphics cards.

The cooling of the GPU is improved, among other things, because MSI uses metal fan blades instead of plastic. Because this is a sturdier material, MSI can make the blades thinner, leaving more room for airflow.

The manufacturer has also developed heat pipes with spiral grooves. These should increase the contact surface and therefore improve the efficiency of the heat pipe. MSI also shows a thermal pad and baseplate with a diamond grain coating. These should be able to dissipate the heat better. The top and bottom of the baseplate do have a layer made entirely of copper.

Safeguard and reusable eFuses

MSI also integrates Safeguard technology into its high-end video cards. This technology is already available in the company's power supplies, but now MSI is integrating it directly into its video cards. Safeguard alerts users if a significant current or voltage imbalance is detected. In such a case, an LED on the card lights up and a beep comes from the speaker. After two minutes, a 70 percent power limit is set.

Furthermore, MSI will use a reusable eFuse in future high-end cards. According to MSI, this electronic fuse has a response time of approximately 200ns in the event of a short circuit. The eFuse automatically resets when the user disconnects the board from power and does not require replacement.
