Modders create quieter RTX 5090, 5080 cards with 3D printed shrouds and Noctua, Phanteks fans

Leave it to modders to make quieter versions of the NVIDIA GeForce RTX 5090 and RTX 5080 graphics cards, with some rather awesome-looking custom Blackwell cards. Check them out below:

The better-looking of the two -- at least to me -- is from "Ultimate Shrouds", which is in the video above. This mod uses the MSI GeForce RTX 5090 VENTUS graphics cards which can now sport an incredible 4 or even 5 fans.

We have a custom 3D-printed shroud that holds 2 x Phanteks T30 fans, and 2 x Noctua NF-A6x25 PWM fans, but this mod can also support a third T30 fan on the back.

Under full benchmark loads during a maximum noise test, the modded MSI RTX 5090 VENTUS graphics card with its Noctua and Phanteks cooling fans makes just 42dB of noise, while a similar GPU with stock fans passes 51dB, marking a huge noise reduction.

Redditor "aartr" used a simple 3D-printed adapter for 3 x Noctua fans on his GIGABYTE GeForce RTX 5080 GAMING OC graphics card, with a custom bracket that supports 2 x 120mm and 1 x 92mm fan, sitting on top of the original heatsink that GIGABYTE ships with its card. There's no alterations to the heatsink with this method, nor any changes to the heatsink, vapor chamber, thermal paste, or thermal pads.

The modder says that the loudest noise coming from the card after his tweaks was the coil whine, and while the GPU is overclocked and consuming 400W of power, fan speeds stick to below 1250 RPM, enough to keep the GPU at under 74C during 3DMark Steel Nomad benchmarks.

u/aartr explained on his post on Reddit with his modded GIGABYTE GeForce RTX 5080: "While the card is already very cool and silent, the minimum 30% fan speed was still audible. Luckily the shroud is removable without taking off the heat sinks (albeit a little tricky) by unscrewing a single screw in each corner of the card".

"The fans are all connected using a single 2.0mm JST-PHD 2x6 connector. I used an amazon connector kit to build a custom fan harness. I've attached a pinout of the female connector in the last picture if anyone wants to make their own harness. The fans are joined by a 3d printed bracket that can be found here".

"I've OC'd the card to run at a constant ~3150 MHz with around 400watts of usage during Steel Nomad the temps don't exceed 74c at around 1250RPM (using a custom fan profile). At this point the slight coil whine is the loudest noise coming from the card".
