I used a 7-pin to dual 4-pin adapter from GPUConnect and a 3D-printed bracket from an Etsy seller named BingsDIY. My idle temperatures dropped from the mid 40s to the low 30s, with a noticeable improvement in noise levels.

My Prime fan was faulty, but instead of sending it to Asus, I decided to rebuild my system and deshroud the GPU with high-quality fans. I heat-tapped the top for the GPU bracket holder and melted part of the insert where the GPU fan cables connect so I could hide them inside.

I also replaced the thermal paste with Kingpin KPX, though I didn't touch the thermal pads. I’m very happy with the results. At idle, the fans run at 300–400 RPM at 34°C. While gaming, the GPU stays below 56°C and the fans don't exceed 900 RPM.

This is all without any tuning. At stock settings, the three tiny original fans would exceed 1500 RPM and the temperature would go above 60°C; the two 120mm fans are much more efficient. I’ll make sure to provide a very detailed write-up once the entire build is finished.
