A YouTuber customized their PC's airflow system by designing and 3D printing custom intake and exhaust ducts, inspired by a high-performance air intake system on their Audi RS3. They used Fusion 360 to model the PC's interior and create the ducts, which were then printed on a high-end 3D printer. The results showed a significant improvement in cooling performance, with the GPU temperature dropping by 8°C and the CPU temperature dropping by 10°C. The YouTuber notes that while this solution has limitations, it demonstrates the potential for improved airflow design in PCs and highlights the inefficiencies of traditional case airflow systems.
Here are the key facts extracted from the text:
1. The author has an Audi RS3 that has been heavily modified, including the installation of a massive carbon fiber air intake from Eventuri.
2. The author wanted to apply a similar design principle to their PC build, creating dedicated airflow paths for the CPU and GPU.
3. The PC build features a 24-core Intel 13900K processor and an NVIDIA RTX 4090 graphics card.
4. The author used Fusion 360 to 3D model the PC build, including the case, CPU cooler, and GPU cooler.
5. The author created custom intake and exhaust ducts for the CPU and GPU using 3D modeling and 3D printing.
6. The custom ducts were designed to provide smooth airflow paths and minimize restriction.
7. The author used a 3D printer to print the custom ducts, which took several hours to print.
8. The author tested the performance of the PC build with and without the custom ducts, using Cyberpunk 2077 as a benchmark.
9. The results showed a significant improvement in cooling performance, with the GPU temperature dropping by 8°C and the CPU temperature dropping by 10°C.
10. The author also experimented with different fan configurations and found that a top intake, front exhaust setup provided the best cooling performance.
11. The author noted that the custom ducts only work with this specific set of hardware and would need to be redesigned and reprinted for use with different hardware.
12. The author concluded that the custom ducts demonstrated the potential for improved cooling performance in PC builds, but also highlighted the limitations of this approach.
