Redditor creates a custom GeForce RTX 4090 Noctua Edition GPU
Noctua haven’t made an RTX 4090 Noctua Edition, but modders have!
Earlier this year, Noctua and ASUS launched their RTX 4080 Noctua Edition graphics card, merging together the GPU manufacturing capabilities of ASUS and the heatsink and fan design prowess of Noctua. When this graphics card launched, many wondered if Noctua had plans to create a custom RTX 4090. At this time, Noctua has never commented on the matter.
With the lack of an RTX 4090 Noctua Edition graphics card to purchase, a Redditor called zaME19 has taken matters into their own hands. Using a 3D printer, an Inno3D RTX 4090 and three 92mm NF-A9 fans, they have created a custom Noctua Edition RTX 4090. This change adds quieter and more powerful fans to Inno3D’s RTX 4090 using a 3D printed shroud to deliver lower noise levels and and reduced thermals.
zaME19 has claimed that their custom RTX 4090 graphics card is 8-degrees cooler than his stock Inno3D RTX 4090. They also report that the GPU is a lot quieter under load. Printing the custom shroud for this graphics card took too attempts, with zaME choosing to use PLA to create the shroud.
Adding 25mm thick NF-A9 fans to this custom RTX 4090 graphics card makes the graphics card much thicker than before. GPUs typically use slimmer fans, which often need to run at higher RPM levels to keep GPU thermals in check. While thicker fans can often provide the same airflow at lower noise levels, their added thickness can be a problem. This is especially true for users of PCIe add-on cards.
This custom RTX 4090 is the first that we have seen that uses Noctua’s NF-A9 fans. Today’s example uses Noctua’s standard black/beige colour scheme. However black Chromax versions of these fans are available for those who want a stealthier look.
