A resourceful Reddit user has developed a Noctua cooler with three fans for the NVIDIA GeForce RTX 4090 GPU – with the help of a 3D-printed fan grille. As he reported on the online platform, he was able to achieve a significant improvement in cooling performance.
The grille was designed by user “zaME19” and fits onto the Inno3D RTX 4090 board. It enables the installation of three 92 mm NF-A9 fans, which are particularly quiet thanks to their SSO2 bearings and decoupling. According to zaME19, this achieves up to 8 degrees Celsius lower temperatures compared to the series design. The solution was part of a more extensive Mini-ITX PC conversion.
Such custom designs demonstrate the potential that lies in the individual tuning of graphics card cooling systems. With the help of 3D printing, custom-fit components can be manufactured to adapt cooling performance, volume and appearance to your own ideas.
You can find out more about the design directly in zaME19’s Reddit post.
