Jeez, I remember in early 00s we all had flavor for watercooling and everyone was trying out all possible fans, it was a total show, search for best fans for radiators...

How are you powering and controlling the fans?
Off mobo with software or using an adapter off the gpu? Just curious.

Normally you can do that, they sell adapters for it to connect to the card fan port.
The problem in this case is the red devil xtx bios hard locks to 35% pwm starting point, which is way too high for desktop 3000rpm fans that ramps up to 1650rpm. You can use 0rpm idle, but that's bad for cards.
So Tp4 is using a motherboard adapter and fancontrol software, which works amazing, it's so configurable. For example, after gaming, you can set it to decrease pwm by 0.5% per second, giving you a 60second cool down period post gaming. That's really cool.
There's no reason not to use fan control, it's so good, you can read 2 sensors at the same time, and have it respond to the highest sensor.
So for example, if you have a higher CPU only load, the fans can respond to that independently of GPU or respond to a high GPU only load, any reasonable logic you need, it's got it..
That's way better than reading a motherboard sensor, because those sensors have a huge time lag, AND, they don't have a very high dynamic range (temperature delta) for you to accurately tune the fan curve.
Sniping:
finally acquired an amazingly low priced 7800x3d system to pair with my 4080s. paid 550 with no gpu and came with a quality PSU, 4 silent wing fans and it’s an SFF build. it’s mostly white so doesn’t really go with the 4080s, but it was a deal I couldn’t pass up.

Deshroud mod the 4080.
