Question One of my GPU fans works only at 0% or 100% gainward rtx 3070 phantom gs

I upgraded my set up a few days ago to
Asus tuf b650
ryzen 5 7600
fury ddr5 5600
but I kept my rtx 3070 because it was working fine, but now the 3rd fan only spins at either 0% or 100%, I used armoury to try and control the fan speeds individually but I don't get an option for the first so I don't actually know if that spins at all, the second fan works as expected but the third fan goes to 100% no matter what if it's on. I don't have any warranty and I bought it secondhand, it'd be really nice if anyone knew anyway to potentially fix this, because the gpu works great otherwise. I've put in my 1070 in the meantime which both fans work fine on, just because the fan noise from the 3070 is really loud at 100%

Put the system under heavy load and see if all the fans spin, open your case to observe the fans, there is a feature called "idle-fan stop" that turns off fans when in idle.

I'm going to do that just to make sure the first fan spins at all, my main problem is just that fan 3 doesn't have any in-between all of sudden. So when I use armoury or MSI afterburner fan 3 will be at maximum rpm even if I put the fan speed anywhere between 30%-100%.
