EVGA 1080ti FTW3 120mm fan shroud

thingiverse

I got tired of the annoying PWM noise from the original fans and decided to swap them out for two 120mm Noctuas instead. To make this work, you'll need to remove the original cooler by unscrewing it first, then bend and break away some clips that are holding the fan shroud in place, reapply thermal paste, and finally screw the heatsink back on. This particular model uses screws in the corners to keep everything securely in place. When using 15mm fans, you'll still need two slots. The fit of these new fans is very snug, so if you're using a rigid material, you might want to adjust your design to be more forgiving. You won't need any tools for fan mounting, and there are three clips in the middle section where you can tie up cables with zip ties if you choose to use a mini PWM splitter cable. I used PETG to make this model, but regular PLA will likely melt or get close to melting under full load. I designed it using Tinkercad, and you can find the original design here: https://www.tinkercad.com/things/igNPfWF9ezM One thing to keep in mind is that the RAM and power fan headers on this card might not be powerful enough to run a Noctua nf-a12x15 at full speed. However, the GPU fan header can handle two fans running at full speed. I'm not sure what the specs are for these fan headers, so I don't know how much power they can supply or how your fans compare to the originals. While these new fans should cool better, they might draw more power, so be aware of that before installing them.
