I'm planning to swap out the fan on my PSU for a new one, as I'm looking to connect it to my fan controller (Aquaero) instead of resoldering the fan connector. I want to place an external temperature sensor on the PSU to create a fan curve based on that sensor. Where do you think I should position this sensor?

Have you thought about keeping the fan at a static speed? When I modded my PSU before, having a consistent airflow worked fine. Is your PSU getting really hot or is the power draw just high?
I’ve never considered an external sensor for a PSU before! My first thought would be to put it behind the PSU to gauge the expelled air temperature, but if your PSU has a zero fan mode, that might not work. Maybe try placing it at the air intake? Most PSUs seem to base their fan curves more on wattage than temperature, so it could be wise to let it just do its own thing instead.
Interesting idea! I just realized I should adjust the fan curve based on the CPU+GPU package power. But Aquaero doesn't really let me set wattage as a data source, only temps. How about sticking the sensor on the back of the PSU fan facing the internals, or on the outside bottom wall of the PSU?
It's an 850W Cooler Master SFX in a micro-ATX case. The system isn't super hot, with a 9800x3d and a 6900XT. I mainly want the fan to be quiet when I’m not gaming and to stop at idle temps.
