Through airflow mod dropped my GPU temps by 4°C

I found a custom mod kit being sold on Xianyu. It lets you relocate the PSU up into the top fan bracket. This opens up a straight through airflow path alongside the graphics card, and the design looked really promising.

The kit finally arrived after a two-week wait. The finished build turned out absolutely flawless. The crossbar has built-in notches to hold the power supply firmly in place.

My GPU is an RTX 5090 Ventus. I stripped off its stock shroud, then added two 12025 fans plus two 6025 auxiliary fans. Under a 600W Furmark stress test at a 25°C ambient room temperature, GPU temperature dropped from 71°C down to 67°C.
